SOLID CARBIDE DRILLS USER GUIDE Regrinding Instructions for SCDT GYRO Auxiliary Devices for Lathe Machines Pre-Thread Solid Drills Designed to Correct Misalignment For each grinding operation, rotate the drill on Stationary Operation 180° and repeat the grinding procedure. Drills can be used on sloped surfaces up to 6°. When drilling sloped surfaces of more than 6°, reduce feed by 30-50% during penetration of up 45° to 5 mm depth, or use a spot or pre-hole drill to 7°ÊspiralÊrelief avoid drill deviation or poor drill performance. 1 Primary Clearance T.I.R. max. 0.02 a° D Range 7 0.8-6.0 10 >6.1 Angular Adj. 1° 2 Secondary Clearance Radial Adj.
