Be sure the bits are not cracked, chipped, or discolored. Rotate the bits as needed. Replace worn bits when all three corners have been used. Only use bits supplied by Rotunda as others may provide an inadequate surface finish. (201RQ086) Rotunda bits are made of special material and ground to remove chips and provide the proper clearance angle; other bits are not made of the correct material and rely on the lathe to provide the proper clearance angle. Be sure the cutting bits are correctly installed. NOTE: The cutting bits for this lathe are specially manufactured. DO NOT use alternative bits. 92 September, 2005 Brake System Diagnosis and Repair
