Threaded Hole Lead In Chamfer at Mia Stapleton blog

Threaded Hole Lead In Chamfer. (the tap will cut whether you have a chamfer or not.). Rolling a burr on the top side of the threaded hole could cause the go gage to not enter the thread, even though a good thread was produced. The most efficient, quickest way to produce a chamfer in a hole that’s to be threaded is with a step drill that combines drilling and countersinking. End of thread at undercut or recess should also be chamfered at 45°. Noboby cares, just make it a 90 and it goes in just fine. Exact angles can not be produced due to the displacement of the metal forming the thread. The specs call for a 120 degree chamfer in the hole. The chamfer/thread/reverse method refuses to work on this. When threads are rolled, the angle on the first and last threads may approximate a 45° angle. 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. If the top of the hole is not chamfered prior to tapping, adding one will help correct this problem. Also, when i try the hole command, and offset the threads from the top. You don't chamfer the hole just to start the tap cleanly without raising a burr.
