- Jul 6, 2010
I learned the difference when I first started parting off back in the early 50s and my boss asked me if I had suffered long enough with the wedge blade. When I asked what he meant he handed me a "T" blade and said see for yourself. I never went back to the wedge blades as I learned when young not to make my job harder than it had to be.

Date: Tuesday, July 6, 2010, 6:45 AMI bought all my parting toolbits years ago, and they are all the wedge type. However, one of 'em is now only an inch long, and I'll get one of the T type to replace it. Never had any trouble with the wedge type, once I learned how to sharpen & set 'em properly. Until then, the less said, the better.Mert-----Original Message-----

This is also why they do not require a heavy rake like the wedge blades do and why they stay sharp up to 20 times longer. On my CNC at work wedge blades neded to besharpened every 3 hours in production while "T" blades were good for up to 36 hours on the same job. After using the "T" blades for over 20 years in production work I find it amazing people still waste their money and time on the silly wedge blades!
