Vitrified Bond Aluminum Oxide Hardness Grade M

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.

Advantages:

• Hardness grade M tools are ideal for general use on steel surfaces, providing high abrasive and stock removal rates. • High stock removal rate reduces grinding time and labour costs. • Cost reductions are achieved despite increased tool consumption, since the reduction in labour costs more than compensates tool costs.

Hardness grade M mounted points perform best 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.
