Drill bit sharpening
« on: January 21, 2007, 10:28:11 AM »
Any of you drillers out there sharpen your own drill bits? Or do you send them out. My new driller says he just buys new ones of the ones he dulls too bad to cut. He does have a carbide 1 3/8 he used for me and it cut a great hole without having to sand it out.

Thanks
Shipper

What are u asking from this post? Just if pro shops send out or sharpen themselves?


We used to send out, but now one of our customers sharpens them at work for us. Not to mention we have recieved 3 boxes of free bits, it really dosent matter if we sharpen them or not.


FYI, if you do them yourself, you cant just sharpen them, you have to hone them back to proper width and everything. Very complicated process which i have seen done.

I've seen shops try to do there own on a grinder and just ruin a set of blades. Seriously this is not a do it yourself thing, if you use them for a busy shop. The proper angle of the blade from both side to side and to front to back helps to keep them cutting sharper better, longer.

I have a friend that fortunate for me is the head of tool maintaince at an aerospace company.

I just trade him a ball at cost for doing a full set, plus 3 other insert bits.

I have a drill bit sharpening machine, but bought it used, and have never learned to use it.  I'm not mechanically inclined, so at this time it was wasted money.

I send my bits to a tool/saw blade/equipment place to get sharpened, they do mine for $3 a piece.  They laugh at me, because I come in so much more often, the "pro shops" they do bring their bits in almost destroyed.  I like to keep mine sharp.

I hand sharpen my own bits, a description of my technique is copied below from an earlier thread.  If I were going to send them out for sharpening, I would investigate Jayhawk.  --  JohnP

I'm not aware of any machine to sharpen the type bits we use, but I sharpen mine using a diamond hone (see link below, or any woodworking site will have them). Hone just the cutting edges that form the tip, DO NOT hone the outer vertical edge. It's not a cutting edge and honing it will reduce the diameter of the bit. I do this free hand using water as a lubricant and count the strokes so I do each side exactly the same amount. If you have any doubts about how to do this, find a bowler who is also a woodworker and get him to help you. Give him a good discount on purchases. If anyone knows of a machine or even a honing guide with the correct angles, I'd like to know where to get it. -- JohnP

Added on edit: I hone all my bits once a year during the summer and the more used bits one additional time during the year. It takes roughly 5 minutes per bit. But I only drill about 150 balls a year.
