A whole bunch of years ago, the shop I was working in purchased a small floor standing grinder that had a 90deg table positioned over the wheel in such a way that as we sawed square stock to keystock length, we simply slid the keystock over the table which deburred and put a specific sized 45deg chamfer on the key. It was quick n easy, the chamfers were uniform, and even me of little brain could operate it successfully. The table was adjustable at lease from 45 to 30 deg's, because I remember using both those settings. Something like that would sure come in handy at the shop I'm in now, but as I ask around about this product everybody thinks I'm nuts. Well they may be partly right, but I'm sure about the grinder. If anyone knows about a product like this, I would greatly appreciate any info you would be able to share. Thanks, K.

Kay, I believe what your looking for is the Bur-Beaver mfg by Simco.
I tried to find a link but couldn't find one.

Kay, I looks like Harig bought Simco out and are mfg. the Bur-Beaver. I'll be darned if I can find a distributor. I'd try phoning Harig direct.

I liked the idea of that tool but couldn't afford it at the time, so I made a table that sits on the mill. The top is tilted at 45 degrees with a fence along the back edge at 90 degrees. The corner is cut out to allow room for the bur. I used it with a fine pitch multi-flute end mill. It worked quite well. I would guess the commercial version works even better because I believe it has a much higher spindle speed.

Gary, I believe they use a carbide burr in their machine. MSC sells the replacement cutters, but not the machine.

If it's like anything else at MSC lately, they probably used to stock them, but now they don't (at any location), the price has gone up 30%, and it takes a week or more to get them.
