Feb 16, 2006· I bought a Darex mill sharpener about a year ago and it works great. Before that I used to touch up cutters with a dremel. The hard ones were when I completely trashed an end and had to start over. Learning to do by hand teaches one alot about tool geometry and reliefs. Same for drill sharpening.
Mar 22, 2005· The biggest problem would be getting the teeth equal such that the end mill performs properly. A hand gashed end mill would be difficult to sharpen after gashing.

The big problem with sharpening end mills is that few have the equipment necessary to do an adequate job, and information on cutter grinding is not easy to obtain.

Apr 17, 2019· all 2 flute end mills can be sharpened by hand so basically only one flute is cutting like a 1 tooth flycutter. like in over 4 decades of machining and if you run out of a certain size end mill and you really have to use that size i have maybe a few hundred times hand sharpened a 2 flute end mill to act as a one flute end mill to get the job done.

Sep 07, 2013· Sharpen it like an ordinary end mill and it will scream bloody murder. You have to spin-grind it and then back it off, which you can't do on the Darex. Or at least not very well. I'd guess that most CNC shops today use carbide because of the spindle speeds available on the machines. HSS end mills are therefore most used on Bridgeports.
