All About Mini Circular Saws

Professional craftsmen have to carry out an impressive amount of carpentry work. That is why it is much more convenient for them to use stationary circular saws. As for home craftsmen, who rarely encounter work of this kind, they do not really need this tool, and they need a lot of space for it. Neat circular mini-saws are in great demand today.

It is worth considering in more detail what qualities and features such thoughtful and practical tools have.

Currently, the range of tools for both professionals and amateurs is very rich and striking in its diversity. The consumers are faced with the widest choice of devices for carrying out almost any work.

Circular saws, made in mini format, have been singled out as a separate niche relatively recently. On the territory of the Russian Federation, such interesting and functional devices first appeared under the Rotorazer brand. The specified name is still applied today to a similar class of electric tools.

The popularity of the compact circular saw was not long in coming.

The Rotorazer is a narrow focus instrument. He is a representative of a new generation and can seamlessly replace a classic circular saw or sander... Such devices are relevant for both home and professional work. Often, the use of a rotoriser is resorted to in various workshops where furniture is serially assembled. A small circular saw can easily replace bulky equipment, as it is no less functional.

In addition, this multi-tasking tool is very convenient to use. Most modern mini-saws are equipped with comfortable handles and other little things for the convenience of the master.

Few people know that the brand called Rockwell became the pioneer in the new generation of household tools. More than 15 years ago, the brand introduced the first circular mini-saw, the Versa Cut. Her build was in many ways similar to the good old grinder. This circular saw from Rockwell was presented in several functional models. Each was characterized by outstanding performance and safety performance. The kit included a good solid type casing.

With the help of such a model, it became possible to cut a variety of materials, which had a serious impact on the popularity of such a tool. Soon, similar devices found their niche in the European market, but under the Worx brand.

When choosing the ideal circular saw that meets all your requirements, it is important to consider its design features. It is worth familiarizing yourself with them in more detail using the example of a convenient circular saw.

The main working unit of this popular tool is a special saw blade with teeth. It starts to move thanks to a small electric motor. In most modern devices, this disc is located at the front of the entire structure.

Today's manufacturers make sawing blades from a wide variety of steel grades. All of them have the teeth necessary for sawing. Their form, according to the rules and standards, must correspond to the material that is planned to be processed.

As a result, all working procedures are carried out many times faster. The cutting line is slightly uneven.

In order for the master to be insured against serious injuries in the process of performing all work, the saw blade itself is protected by a special casing. In most cases, the top of the box is securely fixed to the maximum. In the process of embedding the blanks, the lower part begins to rise. The motor of this device is housed in a miniature body that blends seamlessly into the handle.

Small-sized models are usually made in a plastic case. And also a number of rubberized parts are always present in it.

The device is equipped with a small start button. In most cases, it is located on the handle. For large units, the handle is at the top, for mini-circulars it is at the rear. The specified location of the handle makes the small saw more maneuverable and easier to transport.

Circular saws are often supplemented with a special support platform. Thanks to this equipment, the master can not hold the tool in weight, and the positioning of the saw in this case is more accurate and verified.

Do not think that mini-saws are represented by only one standard model. In fact, many different types of this tool can be found on sale today. It will be possible to find the ideal option for any work.

It is worth considering in detail what types of small circulars exist and how they differ from each other.

This tool has a rather complex design and structure. Typically, these types of tools are designed to work with fairly thin and malleable materials.

Using them, it is permissible to perform the following tasks:

• sawing a tree moving along the fibers;
• sawing a tree across the fibers;
• cut out various subspecies of wood (these include materials such as MDF, laminate and chipboard);
• cut metal with a thin and soft structure.

These tools have the following characteristics:

• they have a very modest size, making them easy to use and move from place to place;
• are lightweight (this indicator rarely exceeds the 2 cm mark);
• as a rule, these models have low power;
• the size of the saw blade in hand saws is small;
• the cutting depth of this tool is also not very deep.

The mini circular saw also has a rather complex design. The main part of this tool is a disc designed for cutting various materials.This element has special teeth and is set in motion by starting an electric motor. Such tools are good in that they are usually equipped with a number of additional functions that are very useful during certain work.

These additions include the following:

• the ability to adjust the cutting depth - for this there is the possibility of displacement of the cutting half of the disc in relation to the thrust base of the device;
• dust and shavings removal - in a number of models of the tool there is a special branch pipe necessary for connecting an industrial-type vacuum cleaner (such revision is especially relevant when it comes to large-scale repair work in order to prevent dust settling on other pieces of furniture);
• protection against accidental shutdown - Often, to initiate a circular saw for wood, it is required to press two buttons sequentially;
• continuous operation (no breaks) - This useful addition comes in handy if you plan on doing fairly long cuts that take a lot of time.

Otherwise, such a circular saw is called stationary. It is multifunctional and very convenient to use. Moreover, such a machine can be made with your own hands, which is what many home craftsmen do. Of course, the specified unit will take up more free space, but also in terms of its functions will be more productive.

Since modern high-capacity batteries have impressive dimensions, they can hardly fit into the small case of a mini-circular. A capacious battery does not fit in this design. It is necessary to take into account the fact that the operation of these tools is good in that you can not stay close to places where there are sources of electricity.

Battery models are also good because their owner can stock up on an extra battery. The latter will make it possible to extend the operating time of the unit.

Today there are many popular and productive models of small circular saws. They are very popular, as they differ in functionality and small dimensions. It is worth considering a small rating of the most popular models.

Good budget-class instruments are produced under the Skil brand. They feature a 10 mm fit and a large diameter saw blade (89 mm). This popular instrument can easily withstand impressive loads, since it is of the highest quality workmanship.

Skil products can be easily compared with expensive items from more famous and large brands. They are focused not only on household, but also on more serious use.

One of the most popular models of the Skil brand is the 5330 model. This instrument is ideal as a professional one.

However, it also has disadvantages such as:

• impressive weight;
• not the best ergonomics;
• high cost for certain - even for the simplest saw, you will have to pay at least 2 thousand rubles.

Makita HS300DWE is a small circular from the universal category. It is designed in isolation from other types of similar technology. It is a standalone addition to the more advanced and professional product lines. This specimen is lightweight - about 1.5 kg.

As for the power of the Makita HS300DWE - the average here reaches about 1400 rpm.

The demanding Dremel Saw Max DSM20 is versatile. It is suitable for metal, tile and even woodworking. In stores, you can find such equipment in different trim levels. The highly acclaimed Dremel Saw Max DSM20 attracts customers with its reliability, durability and brilliant quality. That is why many eminent craftsmen buy it.

As for the disadvantages of this powerful device, they include the following:

• modest dimensions of additional equipment;
• lack of special wick circles (it is recommended to use universal parts).

Compact saws "Rotorizer" are among the most popular and demanded. It was they who became the guarantors of the popularity of many other models of similar equipment. The main advantage of these copies is that they have a democratic cost and low weight. They can be seamlessly transferred from one place to another without any extra effort.

The size of the "Rotorizer" disk can also be different. For example, models in which this element has a diameter of 55 mm are considered one of the most common. In this case, the landing nest will be approximately 11 mm, and the weight will be 1.3 kg.

However, these specimens are characterized not only by pluses, but also by minuses. The latter include the following indicators:

• small discs - these models have small radius sawing discs that are subject to rapid and inevitable wear;
• small cutting depth - this figure is only 12 mm (it will not be possible to properly saw through even a chipboard sheet);
• modest power level - for similar options this parameter is more impressive (approximately 2-3 times);
• the body and accessories of this model cannot boast of impeccable workmanship.

All of the listed disadvantages may seem to some consumers significant and repulsive to purchase. If we consider such models objectively, then they are simple average “Chinese”.

Reviews of such products are mostly positive. Buyers like the good quality, workmanship and cost of the final products... Moreover, they are widespread and available.

The disc for the mini circular must be selected correctly, and several criteria are important.

• The number of teeth. Watch the number of teeth on the disc. Their number will affect the quality of the cut parts and the cutting speed. The fewer the teeth, the longer this or that work will take. At the same time, it should be borne in mind that the optimal indicator is a diameter of 20 mm (there are models up to 85 mm on sale).
• Parameters of the material to be cut... If separation of dense raw materials is planned, it is recommended to use plates supplemented with hard-alloy solders. These devices are more expensive, but can last longer and with better performance.

• Disk type based on engine power. The power level of the engine influences the selection of a suitable saw blade. For example, it is recommended to buy discs with a negative angle with a large number of teeth for equipment that is planned to be operated in a "peak" order.
• External disk size... Be sure to keep track of this parameter of the selected saw blade. This indicator should not exceed the indicators of the casing. If this rule is violated, then the small tool will be less convenient and, if necessary, it will be very difficult to fix it on a special plate.

You can make a mini circular saw with your own hands. A homemade tool can be just as useful and practical if done right. It is very important to first prepare correct and accurate drawings with all specified dimensions and parameters. Having a ready-made scheme in stock, making a small saw can seem very simple and fast.

They make similar devices from different tools, for example, from a drill.

To independently make such a tool for the home, you should adhere to the following sequence of work:

• stock up on steel in sheets (3 mm), cut out a few squares 45x50 cm;
• mark the window for the saw blade with a size of 25x200 mm; cut it with a grinder and align the edges with a file;
• make 4 holes in the base of the circular, while the diameter should be about 6 mm, in order to attach the appliance to the tabletop;

• place the plate on a sheet with a window, center it and place 2 holes for installing the saw pins;
• punch 5 mm holes for the saw mounting studs and prepare the thread;
• fix the studs so that there is about 1 mm to the edge from the front side; now they need to be welded in the front part;
• further, you will need to mark 4 more holes in each metal sheet to fix the racks; for the latter, it is not necessary to make a thread, the studs are welded only to the upper part of the metal base;
• attach the nuts on both sides to the metal sheet below;
• make from the profile pipe supporting elements for the "lamb" to which the ruler will be attached;

• it is permissible to make a ruler from a corner of 32 mm and a pair of cut-off pieces of a strip of steel with a width of 40 mm;
• make grooves for "lambs" in the strip;
• weld the strips to the corner piece by welding;
• make sure all parts are in place; disassemble the structure and then paint.

The result is a small table circular. Take your time. Excessive haste can seriously interfere with such work.
