general description
Bosch miter saws are used to cut not only wood, but also profiles, pipes made of plastic or thin metal. Due to safety precautions and operating rules, miter saws cannot be used by weight - work can only be started after installing the tool on a fixed base.
Products of this brand are supplied for sale in a wide range, which allows the user to choose a unit with an affordable cost and the necessary functionality. Each model is equipped with a dust collector and a protective cover that protects the user from accidental disc flying.
In more expensive models, there is a laser illumination of the cut line, which is extremely necessary in the absence of a previously applied contour. The laser stands close to the spindle, as close as possible to the working disc.

Views
If, in general, we take all the models that the manufacturer offers, then they can be divided into two large groups:
- professional;
- for household use.
From the point of view of design, there is no difference in them, but if we talk about capabilities, then the first are more powerful and reliable. Domestic models are not designed to withstand heavy loads during operation, so they are made from less expensive and durable materials.
In professional saws, every detail is perfectly matched
Accuracy is the first thing a manufacturer pays attention to. There are no errors in the work that are permissible when using non-professional equipment
The second classification of saws:
- ordinary;
- combined.
The ordinary cut quality is much better, but the combined ones have the ability to work at different angles and in any position.
The feed-through miter saw can easily be used on metal or wood.In the design of such a tool, the engine is located to the right of the disc, but there are modern models where it stands at the back, which significantly improves the viewing angle during operation.
Specifications
Despite the fact that all Bosch saws have the same quality and reliability, they differ from each other when you take into account the technical characteristics of the models. It is worth starting to choose such a tool by determining the required power and size of the cutting disc.
In this case, it is worth considering what material you will have to work with. The more powerful the saw, the larger the disc can be installed in diameter, and, accordingly, workpieces of greater thickness, for example, a bar or a log, can be processed.
It should be understood that an increase in the parameters of the considered characteristic leads to an increase in the cost of the product, in addition, the weight of the structure also increases. So, if it is supposed to use the tool in everyday life, then there will be enough power of 1.5 kW with a cutting element diameter of 25 cm.
The second, no less important parameter is the kerf width, which is determined by the diameter of the installed cutting disc. The cleanliness of the cut directly depends on such an indicator as the number of revolutions, therefore, when choosing a model from Bosch, this should be taken into account. The higher the number of revolutions, the better the material is cut. The optimal indicator is considered to be from 4000 to 5000 rpm.
As for the engine inside, the manufacturer offers models with an asynchronous and a collector unit. The first option is durable and rarely requires maintenance. It is installed more often on those models that are expected to be used constantly.
The collector is cheaper, therefore the price of the saw with it in the kit is lower, but its brushes wear out quickly, which is the main disadvantage. Non-professional saws are equipped with such motors.
Last, but not least, the indicator that the buyer should consider is the type of transmission: gear or belt. If you want the tool to please with reliability, then it is better to choose a model with a gear drive, since it is capable of withstanding an increased load. The only drawback is the noise that the unit emits. The belt requires constant tuning, but the saw is quieter with it.
Models
Let's take a closer look at a few samples.

Saw blades for Bosch miter saws
The performance of your miter saw, and the accuracy and cleanliness of your cut, largely depend on the saw blade that is mounted on the tool. The manufacturer, most often, completes the trimming with universal discs, which are not suitable for delicate work and intensive use. Therefore, after purchasing a saw, you need to purchase several discs, which will significantly improve the quality of material processing.
What you need to know when choosing a saw blade:
First of all, you need to pay attention to the size of the disk. The most common sizes are 210mm, 216mm, 255mm, 305mm
Be sure, before buying a saw blade, check the passport of your trimmer.
The second criterion is the manufacturing method
Monolithic - these are low-quality disks, they quickly become dull, more often break.They require a divorce and, as a result, give the worst cut;
Carbide-tipped - they are more expensive, reliable, durable, give a clean and accurate cut;
Tooth configuration
Negative bevel: discs with an angle of up to 5 are used for finishing thin parts, including laminate. When tilted at 15 discs, it is designed for thicker workpieces;
Positive angle of inclination: universal type of sharpening, suitable for fine longitudinal and cross cutting of wood;
By the number of teeth
For sawing dirty wood (eg formwork with remnants of concrete), aerated concrete and similar materials, discs with 12 - 16 teeth are used, for example, Bosch Construct Wood;
High-speed sawing of wood is made by saw blades with 20-24 teeth;
For fine cutting of delicate materials, discs with 40-64 teeth are used.
Rating of the best miter saws
Efficiency, safety and usability of the devices were among the main selection parameters. Before being included in the rating of miter saws, we analyzed the characteristics of products and customer reviews.
Here are the other criteria used to compare the instruments:
- Power;
- Rotational speed;
- Cutting depth and width;
- Methods for processing canvases;
- Types of materials with which the tool works;
- Noise level;
- Power supply methods and cord length;
- Engine protection;
- Diameter and sharpness of the disc;
- Possibilities for table expansion;
- Dust box size;
- The weight;
- Equipment;
- Illumination of the working surface;
- Easy replacement of cutting elements.
One of the selection criteria was the ratio of price and quality of goods, their functionality and availability.
Bosch miter saws PCM 8 and GCM 8 overview
Few furniture or carpentry workshop can do without a high-quality miter saw; this tool is often needed to perform a variety of chores. The Bosch PCM 8 and GCM 8 miter saws are designed for horizontal and vertical cross-cutting of wood and wood-chip blanks. The design of both tools allows you to cross-cut large-sized workpieces without losing the accuracy and cleanliness of the cut.
Bosch is the oldest manufacturer of hand and stationary power tools. The first technique of this brand appeared back in 1886. Since then, Bosch has gone from a small workshop in the suburbs of Stuttgart to a transnational concern with factories operating in many countries and on all continents.
Bosch's domestic and semi-professional miter saws are assembled at the manufacturer's Chinese factory, the company's professional miter saws are manufactured in Germany. In order to understand where this or that tool was made and to avoid acquiring a fake, we recommend that you study the accompanying documents and the marking of individual units and parts. It should be noted that the Chinese assembly meets all internal quality and safety standards. All Bosch tools are certified in the countries of the former CIS, which is confirmed by the corresponding certificates.
Features of Bosch Miter Saws:
- High build quality at German and Chinese Bosch factories;
- Extended up to 36 months manufacturer's warranty;
- Good information and technical support;
- The presence of a large number of original spare parts on the market.
Design features
The miter saw is characterized by a simple structure, which consists of a solid base, including a mechanism, a working disc and an electric motor. In some models, the motors are collector, and in others - asynchronous. The first type is faster, it only requires timely replacement of brushes. The second one is durable, works quietly, but costs more.
The saw base is mounted on a special table with a thickness of 305 to 400 mm. Its disk is driven by a belt or gear drive. In this case, the supply of rotations through the belt is considered the best, since the machine is less noisy, slippage on the pulleys is excluded.
Additionally, the tool set includes a bed.It looks like a movable round base made of magnesium or aluminum compounds. In the process of cutting, the bed has the ability to move; for this, the angle and stop are pre-set.
An equally important element of the saw is the protective cover, which minimizes the risk of injury during work. For safe sawing, manufacturers also equip the machine with an electrodynamic brake, when the power supply is cut off, it smoothly stops the engine. Semi-professional and professional models are equipped with a soft starter mechanism. Each type of saw has a body protection against power interruptions. Since the miter saw is usually small in size, it is compact and easy to place. A wardrobe for her can be made with your own hands from improvised material, or purchased ready-made.
