46#/60#/80#/120#320# Grit

Ruby Mounted Points (16×16×6.0MM) ,5/8" × 5/8", 1/4" or 6mm shank dia. feature a durable 46# grit, Produced in a vitrified bond system utilizing a blend of tough, dark red alumina and friable white aluminum oxide grains. This grain configuration provides an excellent balance between material removal rate and service life. Hardness M is the most commonly specified bond grade for steel and cast steel machining.   Advantages: - High abrasion and stock removal rate in multi-purpose use on steel materials - Shortened grinding times and thus cost savings due to the high stock removal rate - Especially suitable for work on surfaces and edges   Safety notes:   - The maximum permitted rotational speed refers to the unsupported shank length of 10 mm   Application examples:   - Grinding of high-speed steel (HSS) components - Weld dressing on steel constructions   Recommendations for use:   - Mounted points of hardness M achieve their best performance at a cutting speed of 30 to 50 m/s - Flexible shafts, electric grinders and air-powered straight grinders are suitable as tool drives
