Cautions: Maximum Speed Rating: 30000rpm. When using burrs insert them all the way into the chuck or collet. Do not start the burr at a speed higher than 1000rpm. After attaining the starting speed increase to the desired speed but not faster than the rated speed of the burr. Starting burrs at higher speeds, especially with high torque micrometers, can cause the burr to bend at right angles which is dangerous. Always wear safety goggles. Always wear an appropriate mask so you do not breath in particulates and harmful vapors. Always wear hand and body protection. Failure to adhere to these cautions may result in serious injury or death.
