Dremel has decided not to include serrated blades in this tool. This ensures greater tool accuracy in the cutting process. These discs nevertheless have a diameter of 77 mm, which is well within the standard norms. They allow for very clean cuts, but on the other hand they dull quickly. You can fit different types of blades on a device of this kind.

The power is a factor of choice that determines the versatility of the tool. For the dsm20, the brand did not skimp on this important point. The compact saw is equipped with a vacuum connection.

Security measures

Before using the Dremel dsm20, it is important to follow some basic safety rules. The intended work area must therefore be sufficiently clean, well ventilated and well lit. Accidents usually occur in cluttered or dark areas. It is important to ensure that power tools are not operated in an explosive environment.

This recommendation mainly concerns flammable substances (liquids, gases or dusts). Indeed, power tools frequently emit sparks capable of igniting dust or fumes. The unit must also be positioned to ensure optimum safety for the user and to minimize exposure to the cutting disc.

Persons present should keep a safe distance from the work area. The saw is also equipped with a guard to protect the user from disc fragments and possible accidental contact with the disc. Children should also be kept at a safe distance while operating a power tool.

Similarly, distractions should be avoided, as they can lead to loss of control of the tool. The protective cover supplied with the unit must be firmly attached to the saw. It is recommended to use only bonded cutting discs that are reinforced or diamond coated with the dsm20.

Use for cutting

Light pressure on the engine block allows the blade to penetrate any material. The cutting process is continued with a push. After releasing the pressure, the abrasive blade returns to its original position. This is made possible by a return spring between the base plate and the motor block. The Dremel dsm20 allows you to create cuts right in the middle of materials.

It can make transverse, longitudinal, straight and even angled cuts. Whether soft or hard materials are involved, the device can be adapted to several composite materials depending on the blade used. The device allows several different cutting angle settings. Integrated knobs on the base plate are used to tilt the motor block to the desired angle.

Several buttons allow you toto make adjustments to particular angles in order to perform precise operations (for carpenters). The guide is used to make straight cuts over longer distances. On the front and back of the housing, markers are available for setting the path.

If you need to replace a blade or any other part of the saw, the operating instructions provide all the necessary information. It is important to follow these instructions.
