Smaller burrs require faster speeds. 7, Soft materials, such as aluminum, use a grinding oil to reduce debris clogging. Grind glass, use water as lubricant. 8, Elongate holes, grip tool firmly with two hands and use a swinging motion, which prevents chatter, result in a safer cut. 9, Avoid impact loads, otherwise parts teeth will break off, shank will bend. Do not sink the burr for more than 1/3 of its periphery. 10, Recommendation for drives: shank 1/8" (75 to 300W), shank 1/4" (from 300W), for coarse cuts, 500W+ advantageous.
