Recommendation: 1. Grinding welds, hardened steel, hard rock, a tool drive output of 300-500 watts is optimal. 2. For beginners pls choose more smaller burr head dia. than the holes’ dia. and swing-move the burr to enlongate holes, otherwise the burrs will chatter in narrow holes caused by not grabbing tool stably. 3. Gently press rotary tool, let speed do the work.
