Resin bonded cutting blade (also known as resin bonded cutting blade) is a high-speed cutting tool made by pressing abrasives (such as alumina, silicon carbide, diamond, etc.) and reinforcing materials (such as fiberglass mesh) with synthetic resin as a binder. It belongs to a type of grinding wheel. It is widely used in various fields such as metal processing, building decoration, and machinery manufacturing, and is an important cutting tool in industrial production.

M series cutting discs are 100% produced in European factories, with more than 70 years of production experience and excellent quality. They are ideal for metallographic sample cutting. It is very important to match the appropriate cutting disc according to the hardness of the parts to be cut. When the parts and cutting discs do not match, there will be resistance and vibration, noise, cutting deviation, burns, etc. We have selected several typical hardness ranges for selection.

M40A series, suitable for cutting black metals, hardness range 20~40HRC
