PFERD Vitrified bond, aluminum oxide, hardness grade M mounted points are developed, manufactured and tested according to the highest quality standards.
Hardness grade M mounted points are made of a mix of dark red and white aluminum oxide grit in a vitrified bond. M is one of the most aggressive abrasive grades.
Best perform at a recommended peripheral speed of 6,000 - 9,800 SFPM in surface grinding applications. Suitable drive systems include flexible shafts and electric or air-powered straight grinders.
Hardness grade M mounted points are ideal for general use on steel and cast steel surfaces, providing high abrasive and stock removal rates and increases productivity.
For general (universal) use, the emphasis is on the balance between grinding output and service life on steel and cast steel.
