Solid Carbide Chamfer End Mill 60°90°120° 

Solid Carbide Chamfer End Mill 60°90°120° To determine the longest chamfer for blind holes, subtract the full thread length required plus one pitch from the drill depth.  The extra pitch enables clearance at the bottom of the hole for spindle over-spin and chips. Then divide this figure by the number of threads per inch (TPI).
