Title: Step Drill Bits
Post by: Exact Blade on August 12, 2013, 11:32:17 PM
Can step drill bits be sharpened efficiently on the t7?
ie the Lenox Vari-Bit?
Thanks

The only grinding that should be done on those, is on the flats, and IMO the Tormek would not be the best tool to try to do it.

Huh... Interesting thing to sharpen. :)

T7 might work: http://tinyurl.com/k9edp8f
It is a grinder after all.

Bet this would work, but that first drill bit you sharpened would be pretty expensive.  But after that... they are all free!

Grepper, you have to think of the long term usage cost.  While this machine might be just a little pricey up front, the motor uses only a little more electricity than a hundred watt bulb when it is running. :D  I'm sure a tool hawker would not miss this point.

Mike, an old Bridgeport milling machine would probably do this flat work well.  You could put it where your workbench used to be. ::)
