Cutting discs for grinders

The versatility of angle grinders is maximized by using specific cutting discs for different applications. These essential accessories allow you to make precise cuts on metals, building materials, and other resistant substrates with ease and control.

The blade's composition varies depending on the material being cut: fiber-reinforced blades for ferrous metals, silicon carbide abrasive blades for non-ferrous materials, and special blades for stainless steels that reduce the risk of surface contamination. The blade's thickness , generally between 1 and 3 mm, directly affects the cutting width and cutting speed.

The outside diameter must match the machine's specifications, with standard sizes of 115, 125, and 230 mm for the most common applications. The center hole must fit snugly on the grinder's shaft to ensure stability during high-speed rotation, avoiding dangerous vibrations during use.

The maximum permitted speed , expressed in meters per second or revolutions per minute, represents a safety parameter that must never be exceeded. Higher-quality discs often feature internal reinforcements that increase their resistance to breakage even under demanding working conditions.

The direction of rotation , clearly indicated on the blade, must be observed to ensure cutting efficiency and prevent accidents. The contact angle between the blade and the material significantly affects the tool's life and the quality of the cut: excessive inclination can cause breakage or inaccurate cuts.

Makita blades undergo rigorous strength and balance testing to ensure reliability even in the most intense applications. Proper storage in a dry environment prevents moisture absorption, which could compromise the blade's structural integrity. Careful handling during assembly prevents invisible micro-fractures that could develop into dangerous breakages during use.
