Is it possible to drill with a drill bit?
Greetings! This article is about whether or not you can use an electric screwdriver to drill through concrete. It happens so that you need to make a hole or a dimple in the concrete, and you do not have anything other than an electric screwdriver at hand. You’ll have to think about what to do with it. There are of course impact screwdrivers, but even they can not cope with concrete. At most they can handle a brick.
Of course, I still recommend that you get a rotary hammer for such cases. Even the cheapest ones. Then you can make a hole in seconds. But if you need to get the job done right here and now, you can try the following method. True, in addition to an electric screwdriver and a drill bit for it will need two more things. a puncher and a hammer.
You can use an ordinary metal drill bit. but after this work it will instantly blunt and you will have to sharpen it later for metal drilling. If the electric screwdriver is an impact drill, then you can use a brick drill bit with a carbide tipped end.
How to drill?
- First, you put the puncher to the desired place and hit it with a hammer until there is a certain depression.
- Then get an electric screwdriver and use the drill bit. This way you will remove what the puncher has crumbled, and you can also move forward a little more, as the drill is able to drill into the mortar. But it can’t handle coarse filler like stone or rubble, so it can only drill until it hits them.
- When the drill bit hits a rock or gravel, again take the punch and hit it with a hammer.
- Repeat the action until you get the desired result.
The work is quite difficult and requires a lot of effort. But still leads to the desired result. That is, the work that the peorator does on the fly, in this case you have to do by hand with a drill.
If you bump into a rebar, change the drilling location. Of course you can try to drill through the rebar with a drill bit for metal, but it will be even more time consuming, so it is easier to change the place of drilling.
Drilling with a diamond drill bit
In fairness it is worth writing about such a method, as a diamond drill bit in the concrete.
There are special drills for diamond drilling, which are quite massive machines that drill with diamond crowns. And theoretically such a drill bit can also be adapted to an electric screwdriver. These crowns have a small 1/2-inch threaded rod as the seat. And if your electric screwdriver has a 13 mm chuck rather than a 10 mm chuck, you can get a drill bit like this right behind the drill bit.
If the chuck is 10 mm, then you need to think of some kind of adapter.
The impact drill cannot replace a rotary tool. And vice versa? After all, many models have a non-impact rotation mode. so can’t you drill metal and wood with a peorator? In principle, you can. over, the peorator usually has a more powerful motor than most household drills, so it is more likely to cope with drilling large diameter holes, both in thick boards and in metal. But there are a few subtleties.
First, the chuck. Virtually all wood and metal drill bits have either a round shank for the chuck, or a hexagonal or tapered shank. they won’t fit in the chuck. Some impact drills come with a removable chuck for such cases.
For other torches there are adapters that allow to fix a chuck with SDS (or SDS-Mach) shank. it can be installed in a chuck of the torch instead of the drill and clamp the drill bits in it.
Secondly, the rotational speed of the cutter is often quite low. up to 1000 rpm or less. This may not be enough for drilling metal, pay attention to this parameter when choosing a tool if you are going to use it as a drill.
Thirdly, the drill chuck is not fixed rigidly on the tool axis, and the play in it is much bigger than in a drill. especially when using an adapter. Therefore, you should use the torch as a drill only when the runout of the drill bit will not damage the work material or the drill bit itself.
It is convenient to use the Peorator as a drill with Levis spirals, with wood core bits, with thick metal drill bits for small-diameter drill holes.
Drills thinner than 8 mm should be used with caution, as should feather drills and Forstner drills. wedging and skewing the drill bit can cause damage to the workpiece (or the drill bit itself).
Power and speed when working with metal
It is important to choose the right tool. your rotary tool, drill or electric screwdriver. for the holes you want to make in the metal. You can not make big holes at once if you use a drill with power under 700 W. A hand drill under 700W is best used for drilling holes up to10-13mm in diameter.
It is important to choose the right speed for your drill or electric screwdriver. Because your drill bit will burn out at high RPM. You will ruin it that way.
The metal should be drilled at low to medium speed, not exceeding 500-1000 rpm.
The larger the diameter of the drill with which you are working, the lower the speed you should choose.
Can an electric screwdriver drill a concrete wall. Can an electric screwdriver drill concrete. Service-Instrument
Greetings! This article will talk about whether an electric screwdriver can drill concrete. Sometimes it happens that you need to make a hole or a recess in the concrete, and except for an electric screwdriver at hand do not have anything. You have to think about what to do with it. There are of course impact screwdrivers, but even they can not cope with concrete.
Of course, I still recommend getting a torch for such cases. Even if it is the cheapest. You can make the holes in seconds. But if you need to do the work right here and now, you can try the following method.
True for it in addition to an electric screwdriver and a drill will need two more things. a puncher and a hammer.
You can use an ordinary drill bit for metal. but after this work, it instantly blunted and to drill metal it will then have to sharpen. If the electric screwdriver is percussive, it is possible to use a drill bit for bricks with a carbide tipped tip.
Concrete structures are very strong, so it is quite difficult to drill them yourself.
This is due to the fact that for the creation of concrete products uses crushed stone, and when during drilling, you fall on it, the process is greatly hampered.
The need to drill a concrete wall occurs quite often, it is necessary for installing shelves, cabinets, air conditioning, wallpapering, fixing light fixtures, when attaching insulation or during plastering walls to fix beacons.
There are several ways to solve this problem:
Remember that for walls made of relatively soft materials, you can not use pobedite drills, as holes will be uneven and the wall will collapse. To work with metal with such a tool is also impossible.
To create holes of large diameter or to cut a doorway, diamond-coated ring drills are used. To use such a tool it is necessary to use special machines, they allow you to make holes up to 250 mm in diameter.
Since the cost of such equipment is high, it is easier to hire professionals or you can rent it.
How to drill a hole in a concrete slab if the drill collides with rebar
If you hit rebar while drilling, the first thing to do is not to get too hot. When drilling a concrete slab the drill bit or the drill bit hit an obstacle. you should stop drilling.
Stop, and make sure that the obstacle you hit with the drill is not an electrical cable. Take the indicator screwdriver and bring it close to the obstruction in the hole. If the indicator light comes on, it is a sign that you need to be careful.
You might have run into an electrical conductor.
!If you make sure that you hit an electric cable in the drill hole, you should suspend work to repair the damage.
If you hit the rebar while drilling, you should not be in a hurry to drill it. The first option is to try to go sideways with the drill bit. Be careful when doing this, as the drill can jam.
If this happens, here are ways to remove the jammed nozzle.
This option is appropriate for those cases where it is not so important that the hole turns out flat. Try to bypass the rebar by pointing the drill sideways, and thereby eliminate the need to drill through the metal. If, however, you need to get an even hole, then it is better to step back a few centimeters from the original location, and make a new opening.
What is the best way to drill
As mentioned before, you can drill through a concrete wall in several ways, let’s look at each of them in more detail.
When using a rotary tool or an impact drill, you need to switch them into shock mode, insert the working tool with the pobeditovye tip and it should be directed perpendicular to the surface of the wall.
If you are going to be drilling for a long time, use a regular drill or an electric screwdriver
periodically moisten the drill bit, so that it does not overheat too much.
DON’T DRILL CONCRETE Until You Watch THIS VIDEO!
After you have drilled to the required depth, you must pull the tool back without turning off the torch. To get the dust out of the finished hole, it is necessary to hammer in and pull out the drill bit several times.
Use a regular drill or an electric screwdriver
If you do not have the above described tools, you can also do this job with a regular electric drill or a powerful electric screwdriver.
Tips for using the torch
Here are a few tips that will allow you to use the torch more productively and safely:
- When drilling and chiseling, do not press the tool body hard, it will overheat the motor and waste energy, but it will not speed up the operation.
- Choosing the right accessories for each job is the key to getting the job done quickly and successfully.
- During local work with the rotary hammers long sweeping hours can be avoided by holding the hose of the working vacuum cleaner under the place of drilling or chiseling. When screws need to be driven into the concrete surface, metal anchors are inserted into the drilled hole. Plastic dowels are sufficient for light usage.
- Use water to cool the drill bits and get rid of dust only after you have familiarized yourself with the composition of the drill bit. The fact that some carbide drill bits can break when cooled by water.
- Use special diamond drill bits instead of drills for larger diameters to reduce labor costs and save time.
Tips for caring for the rotary hammers
To keep the torch long and without damage, it is necessary to observe a number of recommendations for its care and storage. For each model of impact drill, there is an instruction manual that details how to use and care. However, a number of rules can be made for all peorators that must be followed in any case.
The tool must be stored in a dry, ventilated room in its case or without it. Before working, check the insulation of the wire as well as the body of the torch itself. It is recommended that the rotating parts of the tool be lubricated periodically, and that the grease be completely replaced with new grease if its lubricating properties deteriorate.
Given the fact that the cooling of the electric motor occurs through the air flow into the holes in the body of the torch, you need to ensure an unimpeded supply of air flow. This means that the tool must be clean, without blocked slots, and when working it is forbidden to cover the holes with the hand.
If the peorator fails, it is necessary to contact professional craftsmen, not trying to fix the problem yourself. Make sure that only original spare parts were used for the repair.
What time is it allowed to work with the fan
Performing repair works with the use of a peorator in an apartment building is inevitably connected with causing inconvenience to neighbors. To avoid conflicts or even fines you need to know your rights and responsibilities. According to the building code, you may not cause noise or vibration in the evening between 11 p.m. and 7 a.m. This means that during this time, not only is it prohibited to work as a horn, but even to talk, sing and play musical instruments loudly.
Work by a pedestrian during rearrangement or redevelopment of the premises in apartment buildings is prohibited at weekends and on public holidays, i.e.к. this action generates noise and/or vibration. It is also not allowed to carry out such work on weekdays between the hours of 9:00 and 19:00.
It should be understood that the level of noise coming to the neighbors from the work of the screwdriver, directly depends on the quality of sound insulation performed and the thickness of the ceilings in the house.
How to drill with the torch if you are faced with this tool for the first time and do not know its specifics ? Naturally, the peorator, like any electric tool, is source of increased danger. I will not tell you what to do to avoid electric shock, and to set forth all the other elementary truths, because you can familiarize yourself with all this in the passport, which is attached to the tool. And we’d rather talk about something else.
What can be drilled with a peorator? ? Typically, it is used for drilling in mineral materials based on concrete and cement, as well as stone, asphalt, and even soil. It is also used for stirring dry construction mixtures, and not only that. it can drill into wood, metal and even drive self-tapping screws in standard drilling mode. over, a jackhammer mode tool can be used for rough piercing and demolition work.
To drill with the rotary tool, hold it straight, do not force it (or do not force it at all if the material is soft, like foamed concrete). Tile, plastic baseboards with cable channels and cable channels themselves are better to “pass” in the drilling mode first, and then, when you need to drill a wall, you turn on the impact mode.
Drilling asphalt with a peorator may be necessary for a variety of reasons: for example, it will be work to install half spheres, or to repair a fence. The asphalt is laid on a firm cushion of sand and gravel, which is well rolled by a roller or tamping machine.
However, when you start drilling the asphalt and reach the cushion, some of it softens from the vibration of the drill and displacement. This causes the pieces of gravel to move relative to each other, and the drill can be jammed in the hole. If you feel that the gravel starts to “tumble” you must work very carefully and at the first sign of auger clamping release the tool immediately, otherwise you may dislocate your hand.
Next, you need to carefully free the drill (to do this, try to loosen it. firstly just with your hands or pliers, and then with a hammer, and strongly do not knock). If this does not work, you have to bore the asphalt around the auger and then release it (this is very rare and mostly with small diameter augers).
The dangers of sinking into concrete
When drilling very deep holes (usually holes for installation of cables, and their depth can be one meter or more at times, because you want to drill through solid walls) there is another danger.
At depth, the drill can get caught in rebar, and then the drill can be literally torn out of its hands. For this reason, the tool should not be pressed down and should be held in such a way that your hands do not cross (as always). The matter is complicated by the fact that the auger follows the path of least resistance, and therefore can bend and change direction. As a result, the inlet hole can be just 30 centimeters further than the outlet hole.
Thus, choosing a place without reinforcement, you can still stumble on it. It’s hard to avoid, so you have to drill very carefully and smoothly.
Hidden wiring in the walls and plugged junction boxes
Not an insignificant danger are also walled-in junction boxes, which have long been forgotten about (even by tenants), but they still have a current-carrying wires. Such a box is usually easy to find by the “empty sound” when knocking, but sometimes it is deeply walled up.
Concealed wiring is even more dangerous, given that it can be laid however you want. It is said that the wires should, they say, run only at right angles, and to the consumer they are allegedly led exclusively from above. This is nonsense, because, unfortunately, laying (and still laying) cables at any angle, leaving twisted “copper-aluminum” in the walls and grounded on the fixture. So it is very desirable to have a detector of electromagnetic radiation or a proximity probe, with which you can find the current-carrying wires in the walls and bypass them.
Drilling holes for nylon dowels with the perforator
Dowel drilling has the advantage that we need to get holes of the same depth anyway. For the SORMAT 6, for example, it is 35 mm or more. Some especially advanced “craftsmen” wrap duct tape or scotch tape around the drill, thus marking the depth of the hole. But the thing is that the tape or duct tape gets desperately hot while drilling, and then they “crumple and move”. as a result it is possible to drill through the wall, not considering that all this crap can simply melt through (by the way, in the photo you can see sometimes such a fused strip, because I had to use this fascist method more than once, when there was no marker, but it is not recommended to repeat it).

The most effective way to mark the depth is to apply a fat (5mm wide). or larger) mark around the drill with a marker. Such a mark is perfectly visible when drilling, it is not erased for a long time, and if necessary, it can be renewed very quickly. over, if you want to drill at different depths, you can put several marks in different colors and use them. “Yes, but there is a depth gauge !”. right. Lost or forgotten, and in any case in the way, especially in a cramped room. Not to mention the fact that not every pen is equipped with one.
Recommendations for the use of the torch
There are a few basic rules of thumb to follow when using a drill bit. There are only a few of them:
While working, do not press the tool too hard so that the drill does NOT overheat and become bumpy. It won’t increase the speed of the job, but the drill will get damaged and you’ll have to buy a new one. Often they want to drill a deep hole in one pass, but sometimes the drill gets clogged and needs to be cleaned. Therefore, you should periodically remove the hole from the hole to clean the hole and the drill itself. choose a power tool with an aluminum body, but don’t overheat it, and look for an aluminum-plated model. Why you should choose them? It’s simple: they cool better. It is advisable to work with a peorator in rubber gloves with anti-vibration inserts, which can lessen the vibration, although even the tool has special inserts Buy quality drills, because cheap ones break quickly, finally you will overpay more
Work with the peorator at heights should be especially careful, because as a result of jamming, the drill can break and the tool can fall down. Also remember that the sound of the working stroke is very strong. That is why working in a residential area must be done at a strictly set time.
For drilling in concrete, drill bits with a carbide or diamond tip are used. With this tool you can make a small hole (no more than fourteen mm).
The shape of the shank is different from drills. Drills are considered disposable because they cannot be sharpened and discarded when their lifetime is used up. Their advantage is that they are able to remove from the hole the concrete chips from the drilling process. It is reasonable to use this tool when drilling deep holes, including through holes. Drill bits can be used to drill holes with diameters ranging from four to eighty mm.
When drilling holes with a drill bit, rebar is a definite hazard. As a rule, the drill bit immediately burns out after a direct hit on metal. If the tool goes tangential to the reinforcing element, it simply jams and further drilling becomes impossible. so it is more appropriate to use diamond bits for reinforced concrete.
Types of chucks
There is another difference between the drill rocks. This is the type of chuck to hold the cutting tool. The chuck acts as the connecting link between the tool and the torch. In order to work effectively, the clamp must meet a number of requirements.
For example, a chisel or auger should be held securely in the chuck and can be tightened and released easily and safely. The drill must be capable of absorbing the high torque and impact force that the drill bit is capable of. Its shank has a special design for this. The way of fixing the cutting tool in the impact drill is designated as SDS (Special Direct System).
Keep in mind that each mounting system has its own hardware:
- SDS-plus. The torque is transmitted by two symmetrical long slots, and two oval slots secure the shank in the chuck. Shank diameter. Ten mm. This fastening system is used in drills for rocks up to four kilograms
- SDS-top. The system is based on the same principle as the previous one, but it is used for tools with high impact loads, which belong to the medium weight group. Shank diameter. Fourteen mm;
- SDS-Max. The torque in this anchoring system is already transmitted by three long asymmetric splines. The eighteen-mm-diameter shank is held in the cartridge by two oval grooves.
Getting to Know the Air-Assisted Drilling (ARCH)
If you haven’t encountered air-assisted casing drilling (ARCH) before, you’re probably not alone. The ARCH method hasn’t garnered as much attention as some of its flashy friends like sonic, but for drilling in alluvial formations, it’s a solid option that every environmental consultant should know.
WHAT IS ARBOR DRILLING AND HOW DOES IT WORK?
As the name implies, the ARCH method combines direct air-rotor drilling with simultaneous hammering. When using True ARCH, a larger casing is driven into a smaller hole using air as the circulating medium.
WHEN TO USE THE ARCH?
ARCH is best suited for alluvial formations. It is not actually designed for drilling in hard rock, but in some cases it can be used to cut through overburden first and then can be installed on bedrock.It allows drillers to use another method of working the bedrock, such as direct air rotation with a downhole hammer, or perhaps even switch to drilling fluid rotation.
Read about how we combined ARCH with other drilling methods on a project in Harney Basin.
The ARCH can be used in many applications, such as environmental monitoring wells, production and injection wells, soil vaporization wells, and even in the mining industry. It is particularly suitable for projects where aquifers may need to be separated and telescopic casing strings lowered.
WHAT ARE THE STRENGTHS OF THE ARCH METHOD?
ARCH has several strengths. First, because it is an air rotary drilling method, no secondary waste stream is formed, as it would be with rotary drilling or other methods. Usually you only dig material for the diameter of the drill hole you are drilling.
Second, ARCH allows the surface casing to be installed without the use of permanent materials such as steel and cement mortar. This saves installation time, money spent on materials, and simplifies mobilization.
Third, drilling with air in alluvial rock provides almost instantaneous recovery of the drilled rock, which can be seen in a cyclone or container. It makes it easy to determine what formation you are in.
Fourth, like hollow rod or ultrasonic drilling, the well is cased, so the well can be built in a controlled atmosphere. When the casing is removed from the borehole, the ring material is displaced, so the borehole is virtually never exposed to the formation. This prevents the wellbore degradation that can occur with uncased drilling methods.
Fifth, it is a very fast method. Depending on the formation, it is not uncommon to drill 300 feet in four to six hours. This is usually faster than ultrasonic drilling.
WHAT ARE THE TREATMENTS?
As with any air-rotation method, the biggest disadvantage may be the drilling associated with the aquifer. In scenarios where you hit a fertile aquifer, air circulation generates a lot of water. Depending on the project, this may not be an acceptable situation and you will need to switch to another drilling method.
FOR WHAT OTHER METHODS THAT COULD POTENTIALLY BE USED IN THE SAME LITHOLOGY IS ARCH SUITABLE?
At shallow depths, you can use a hollow rod auger. Augers move chips to the surface instead of relying on a circulating medium. For deeper drilling, you can use sonic and potentially direct air flow or dual-tube reversal, depending on how the formation rises. Often the formation will not stand up to air velocity or the ability of water to collapse the well.
HOW TO KNOW WHEN AN ARCH IS THE BEST WAY TO DRILL FOR A PROJECT?
The best way to determine if ARCH is right for your project is to discuss it with a reliable and experienced drilling partner who does not support any particular drilling method. For example, my team recently proposed a project and I brought up ARCH drilling to see if it would be a good fit. However, it turned out that they needed more details about the lithology to fill in the data gaps for the project, which sonic could do more cost-effectively and quickly.
In another example, another client assigned two phases of a project to two different drilling contractors. We were contracted to install 4-inch monitoring wells with slotted casing, and another company was contracted to install 8-inch production wells and 6-inch injection wells with stainless steel meshes. They drilled the wells with rotary drilling mud, which resulted in damage to the well walls and the aquifer.
