GENERAL TECHNICAL INFORMATION FLANK CLEARANCE AND EFFECTIVE INCLINATION ANGLE Inclination angle b of the cutting edges corresponds to a specific thread helix angle l and insures equal clearance angle on both sides of insert. Correct Incorrect aL = aR aL < aR a- Flank clearance angle - Helix angle - Effective inclination angle is achived by selecting the suitable anvil.
