    Do you sharpen your metal drill bits? If so, how do you do it (by hand, bench grinder, drill doctor, etc)? Any tips on how to do it well?

    I normally do my drill bit freehand. It takes some practice but is much faster.
    A good bench grinder, a good source of light and a jig to keep the bit at a steady angle against the grinder wheel. Don’t forget to dress up the wheel after you’re done, specially if you are using it for your chisels like I do.

    P.S. Heat is the worst enemy for your drill bits, so don’t push too hard against the wheel and keep a container with water beside the grinder and dip the drill bits often to keep them cool.

    I’m a big fan of the drill doctor. I usually do a bunch at once as it takes a rhythm to get used to. Keep your bits clean and stone clean.

    I’m looking for good solutions, in the mean time I have a very heavy box that I add to pretty regularly. My issue has been thinking about payback, investing in a system would take me a long time to pay back. I’m interested if I could do them myself with either my bench grinder or maybe rotary tool though.

    I have heard good things about the drill Dr. Seems to me it would pay itself off fairly quickly if you go through a lot of bits…

    ive attemptd it both with the drill doctor and a guide on a bench grinder.. failed miserably so i just tossed the bits.

    small twist bits are what i go through the most because their so small they usually break before they dull

    heres a tip, dont fart in a space suit

    I would think the sizes you use may influence it also. I will break bits before I wear them out with anything less than 3/16 everything above that is used sparingly so they stay good longer. In that respect can last many years with a sharpening here & there.

    When I was working on steel buildings my boss would sharpen bits with the side of the big cut-off wheel on the chop saw…I tried a few times with little to no success.

    I usually just toss them, thought about a drill dr. before but used a friends once with little success. And like most guys have said i usually break the little ones before i wear out larger ones.

    A friend has a Dr Doctor. He takes a load and does them in his spare time.

    I can do it in a pinch on a grinder.

    Just got a drill doctor and it seems to work great.

    I am guaranteed to break them or lose them before I need to sharpen them. Except for spade bits. The cheap ones I end up burning out so they are no good to sharpen, and the expensive ones….I lose. I guess I need some more L-Boxxes.

    Same. I toss them and get new. I consider them as consumables.

    It’s hard to sharpen brad point bits well, which is what I use most of the time.

    I’ve got a box of dull drill bits. I’ve been planning on getting a drill doctor but I want a decent one and those aren’t cheap.

    I have a drill doctor. Tried it a couple times, but it only does the 118° bits. I normally buy 135°, so it just sits there almost new. I find it easier just to stock up on bit sets @ Christmastime.

    I might need to get one of those drill doctors. Are there limitations on the type of bits you can use in it?

    I always sharpen them on a bench grinder. Even if it’s snapped off I just grind a new point on it and have a stubby bit. It’s actually real easy to do, just takes a little practice to get the feel for it. We had another thread about this, but I can’t find it… I posted a youtube link there that shows how I sharpen on a bench grinder.
