How to use

Fit the disc to an angle grinder that accepts 150 mm discs with a six-hole mounting pattern, following the grinder manufacturer's instructions for mounting and securing accessories. Operate the grinder at the recommended speed range printed on the disc or supplied documentation, and use steady, controlled passes when cutting or grinding. Maintain correct body position and hold the tool firmly to control feed rate and contact angle. Replace discs when wear or damage affects cutting performance or safety.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection, gloves, and respiratory protection as required for the material being processed. Avoid side pressure beyond the disc's rated use and do not use discs on tools with higher speeds than specified. Store discs in a dry, moderate-temperature environment away from direct sunlight to preserve bond and abrasive performance.
