Renovator Description
This kind of machine was invented about 40 years ago, but is not widespread. Was reintroduced a few years ago, because the patent for its production had expired. It is a tool based on the principle of oscillation. Transmitted directly from the motor via an eccentric. The head is oscillating with a frequency of up to 30,000 oscillations per minute. Amplitude depends on the size of the eccentric, but the difference is small. It is the high, adjustable frequency of head movement that makes the renovator a useful tool at home. The Renovator is also called a multi-purpose cutter.
They are sold in mains and standalone versions, with a battery. One that runs from the wall outlet is much cheaper. Cordless models give more freedom of action. up to several hours of continuous work, but also cost more. If you can work near a power outlet, it is worth taking a renoovator with a power cord and a full set of “all-in-one” nozzles.
Models from 400W are able to work longer and at higher frequencies, but noticeably heavier. You have to choose between the weight and the vibration frequency. The nozzle footprint is the same for expensive and cheap models. Charged models have a keyless tool change function.
The set of nozzles of the device replaces a number of tools:
Benefits of cordless tools
Cordless models are now present in almost all types of power tools, including in categories previously considered not too suitable for batteries, such as circular saws (for example, the models Ryobi R18CS-0, Makita HS301DZ, Bosch UniversalCirc 12 0, Greenworks G24CS 0) or, say, chainsaws (models Greenworks G40CS30, DeWALT DCM565P1, Husqvarna 120i). This is due to modern battery models that can provide any intensity of operation, especially if you have a spare battery. Their high per unit). And in other things cordless technique is much more convenient: it is more compact, lighter and much quieter, if compared to the models with internal combustion engines). And, of course, no fiddling with power cables.
What’s good about the saber saw
This machine is simple and easy to understand for any user who has at least some experience with power tools. Long body, pistol grip handle, throttle, a couple of switches, working blade nothing new. Even a beginner has no problem figuring out what’s what and will easily find a decent use for the multifunctional machine.
In fact, the sabre saw is an analogue of the familiar handsaw, it is even sometimes called electric sabre saw. The principle of operation of this tool is the same as that of the jigsaw, no wonder that they are very often compared. To be fair, let’s note that the sabre was developed a couple of decades earlier (1927) and became the ancestor of the electric jigsaw. The working blade makes reciprocating movements and with its teeth selects the material to be cut. At one time, the invention of the pendulum stroke was revolutionary, which greatly increased the efficiency of the saw. About it a little later.
Skeptics say that the sabre saw can be easily replaced by any other cutting tool, an angle grinder, a jigsaw or a set of all kinds of saws. But is it?
First, the sabre saw is a truly versatile unit, which is useful to the carpenter, plumber, roofer, finisher, both at the amateur and at the professional level. It can cut wood, wood with metal elements, steel, nonferrous metals, stone, plastic, foam blocks, composites, ceramics and glass. It’s just worth picking the right blade. We have absolute omnivorousness.
Secondly, the tool has a very favorable longitudinal layout. The narrow elongated gearbox and the long blade allow you to fit in very confined spaces. Imagine having to saw a pipe or a beam flush to the wall, no circular saw, angle grinder or jigsaw (with its short saw blade, wide support platform and closely spaced body) will help.
Thirdly, the sabre saw is excellent for work on the weight, including work with parts of any shape corners, planks, bars, pipes, rolled sections. For the same reason the tool is very productively used for pruning trees (landscape architecture), when it is necessary to accurately clear the crown, to saw large branches.
Fourthly, having good maneuverability the thin-blade sabre saw helps to make curved cuts. Sawing curved details in sheet metal, rounding workpieces, making complex constructions is no problem, especially since there is usually a support shoe, albeit not a big one.
Fifth, a sabre saw is indispensable for demolition work. It can be used to quickly saw an old window frame, cut openings, disassemble the steel heating. And ability of the saber saw to cut a wooden bar together with nails or screws hammered into it is really worth a lot.
Sixth, this tool is much safer than circular saws, circular and chain saws. When working with a saber saw there is not so much dust, you do not have to fear sparks, dross, overheating of the workpiece.

Seventh, these saws are unpretentious in maintenance, they are very durable.
Those who could not make friends with saber saws complain about the two-handedness of the machine, the lack of a supporting roller and a full-fledged platform (the withdrawal of the blade). Disadvantages of these nuances can be called conditionally, after all, it is not a jigsaw saber solves a much wider range of problems.
Electric sabre saw repair
How difficult it will be to repair an electric wood hacksaw depends on the specifics of the breakdown. If the sabre saw stops while cutting wood because the protection trips, it could indicate blunted blade teeth or a hard push while feeding.
If you get a beveled kerf. the prism of the guide holder is dirty, blunted blade or it is not correctly selected.
If the electric hacksaw does not start, it can be caused by a damaged cord, discharged batteries (in case of cordless power) or overloading, which triggers the protection.
In case of wrong or weak saw blade fastening it is needed to check if the fastening screw is not worn out. It is possible that a blade with an unsuitable shank for electric sabre saw is selected.
If it is necessary to disassemble the saw it is necessary to unscrew the screws on the handle and pick up one of the plastic parts with something sharp. Sometimes the screws are hidden by the cover, in which case you must first remove it by removing the attachments from the hacksaw. Replacing gears, bushings, bearings is not always possible on your own, if only because you have to find the right parts. In this case, the tool is simply given to a service center for repair.
Jigsaw or circular saw for home use? What are the differences and similarities of working with the tool?
When choosing a tool that will be used in the household for cutting various materials and will replace an ordinary hacksaw, it is often necessary to choose something between a circular saw and an electric jigsaw. To determine which tool is right for you, you need to understand the fundamental differences between the two devices.
What to choose: jigsaw or circular saw?
To decide on the choice of the more preferable variant will help the volume and nature of the work to be done. For example, if you are a novice carpenter or the amount of work does not involve a lot of effort and a long time, it will be enough to buy an electric jigsaw. It can easily handle not only chipboard and plywood, but can also be used for sawing small boards.
For more extensive works, when it is supposed to saw for a long time and in large volumes, it is better to choose a circular saw. It can be used to cut sheet wood, fairly thick boards and bars.
Operating differences and features
Electric jigsaw cuts material through reciprocating movements of the saw, which should be selected according to the work to be done. Some types of the tool allow you to set the oscillation forward and backward to achieve less overheating of the cutting blade and a smoother cut. The jigsaw allows you to make a cut both vertically and at an angle, and the thickness of the material that can be sawn, directly depends on the length of the saw.
Circular saw makes the cut with a toothed disc. This tool must be held with two hands, unlike the previous tool. Most circular saw manufacturers make it possible to mount the tool with the blade upward, thereby turning it into a small machine. The cut can be made both perpendicular to the plane of the material and at different angles. Depth of cut is controlled by repositioning of the saw platform, usually not exceeding 85 millimeters.
Before buying one of these tools, it is not unreasonable to become familiar with their most significant advantages and disadvantages.
Advantages of the jigsaw
- Small size and weight allowing it to be held with one hand
- Quick saw blade change
- The ability to make cuts in any area of the material by pre-drilling a hole
- A variety of shapes can be sawed
Disadvantages
- Overheating of the jigsaw significantly reduces the quality of the cut and leads to a slightly wavy cut
- The cutting depth cannot be adjusted
- Rapid saw blade wear
Advantages of the circular saw
- Long life of the blade
- Ideal for materials where longitudinal or cross cuts are required
- The ability to do large amounts of work without having to stop to cool down
- Greatly increased productivity due to the ability to mount the saw with the blade upwards
Whether one tool can be replaced by another
Although these tools can replace each other in some cases without any noticeable difference in quality of work and convenience of use, the jigsaw is a more universal device. A jigsaw, on the other hand, is capable of much more monotonous work. Although the circular saw has long ago overtaken even the most modern jigsaws by many indicators, but it is sometimes rather laborious to use it, and frequent disk changes when working with different materials will not add convenience. The jigsaw blade can be replaced in a couple of minutes.
Having determined more precisely what kind of tool you need, you can start researching the market. Do not buy the cheapest option: such a tool will be much noisier and will most likely heat up, which will negatively affect its lifespan. And vice versa, it is not necessary to buy for your needs a tool with a whole set of different trimmings and features, most of which are not useful in the household. The best choice would be to opt for a medium-price tool, which will contain a set of the most necessary functions and will not hit the budget.
The device “saber
The principle of operation is simple and borrowed from the jigsaw. The blade moves back and forth with a small amplitude (10-28 mm). In the holder is fixed, as a rule, without a key. The advantage is that you don’t need to study the instructions for a long time to start working. everything is intuitive as it is. Saws have oblong body and pistol type handle with an on/off button. powered from both the network and battery. Holds the “saber” with two hands, a lightweight model can be held with one hand. I pay attention to the last circumstance. it allows you to work with a hacksaw in hard-to-reach places, cut holes for ventilation or sewer pipes, fit and trim boards on the spot.

Jigsaw and jigsaw comparison in application. Jigsaw, or sabre saw? Which is better? A sabre saw is a sabre saw! Jigsaw is a jigsaw! Sabre saw. it is a multifunctional power tool, which is the analogue of a hand saw, but much more convenient and effective in operation. Sabre saw is designed not only for professional craftsmen, but also for those who are far from this sphere. Thanks to this tool one can quickly, and most importantly, qualitatively perform practically any works related to material cutting Saber saw is a multifunctional equipment, which outwardly resembles a drill. Has an elongated body with a handle and operating button at forefinger level. to provide protection when using the tool, there are fuses on the tool to protect against accidental pushing of the button. The device is also equipped with a special cutting blade, moving straight ahead, capable of performing pendulum-like actions (on some models). According to its operating principle and the intended purpose, which will be described below, the sabre saw can be compared to a usual for an ordinary user hacksaw. Electric jigsaw The electric jigsaw is an electric hand tool for sawing various materials with reciprocating motion of the saw blade. The first electric jigsaw was created in 1946 by Albert Kaufmann, an engineer at Scintilla AG (Switzerland). Electric jigsaw. electric compact hand tool designed for sawing wood, metal, plastic and other materials. It was equipped with a reciprocating saw blade. Due to its low cost and the possibility to perform a wide range of works, this tool is widely used for domestic purposes, but it can also be found in the arsenal of professional builders engaged in the implementation of repairs. Carpenters and joiners do not use it much due to the low accuracy of cutting. Band saws, mitre saws, and circular saws significantly outperform jigsaws and saber saws in performance and accuracy.

What is the difference between a jigsaw and an electric jigsaw?
The main and most important difference between electric sabre saws and jigsaws is the difference in purpose of these tools. We can say that an electric sabre saw is designed to destroy, and its younger cousin. to create.
What type of saw do I need for which job?
often than not, the electric hacksaw is used for quickly cutting material, predominantly along straight lines. It can easily cope with constructions of any shape and any material. Cardboard, wood, plasterboard, metal, concrete, glass, ceramics. this is just a small list of materials that can be cut with an electric hacksaw. This kind of work is typical of dismantling and other relatively rough repair jobs.
Electric jigsaw is more suitable for more precise work with flat surfaces and it is more expedient to use it in cases where shape cutting is required.
Another serious difference is the shape of the tools, which determines their capabilities. The elongated body of the electric hacksaw and the relatively long blade let you make a cut in the most hard-to-reach places, where with a wide electric jigsaw is simply impossible to reach.
Thanks to its design and flexible blade, the electric jigsaw can saw down the protruding elements flush with the wall, what a rather wide jigsaw cannot boast. You can easily saw with an electric sabre saw “in the balance”, the electric jigsaw requires a flat surface to ensure firm contact with the material with its working area in order to prevent tool breakage.
Thus, when it comes to deciding what tool is needed: a sabre saw or an electric jigsaw, you should first clearly define the intended tasks.
The electric sabre saw is less fastidious to operating conditions and can work in the most extreme conditions. Even beginners can easily master it. The tool is able to make quite even cuts, but, nevertheless, it is more suitable for rough work.
Electric jigsaw or circular saw: what to choose?
recently, arsenal of every craftsman necessarily had a hacksaw, with which you can cut almost any material. Today, this hand tool is already a thing of the past, and in domestic conditions and in production it is increasingly replaced by an electric jigsaw or circular saw. It remains only to understand which of these power tools is better to choose for each specific case.
