Tapped Hole Lead In Chamfer. I do the math to figure out. The number varies with the pitch of the thread and by the machinability of the material. Grailo is talking about clearance holes, not a threaded hole. Typically on a 60 degree thread a 45 degree chamfer will be cut just beyond the major or minor diameter. On tapped holes the issue is that without a chamfered hole there is a possibility of a burr that will extend above the bearing surface. The tool sequence must be changed if a. Noboby cares, just make it a 90 and it goes in just fine. The specs call for a 120 degree chamfer in the hole.
