    I am tired of having to buy drill bit after drill bit.
    I have some nice titanium coated bits that I would like to sharpen.
    I'm sure I've seen some 'As Seen on TV' sharpener before, but I'm not sure what to use.
    Anybody use one? Recommend one? How do they work anyway?

    i high end ($110) drill doctor works awesome. it takes a little while to figure out how to use it, but once you do, its like having a new drill bit.

    I learned to do it by hand in high school with a bench grinder or sander. One of those best things I've learned as far as fabbin and metal work goes. /forums/images/graemlins/thumb.gif

    Well, think you can learn me how to do it?
    Never heard of that before.
    About the drill doctor - which model do you recommend? They have a couple different ones.
    Are there any good alternatives?

    what size are you trying to sharpen and look at the end of the drill, some are wide web and some are thin...the thin are easer to sharpen...I too do the by hand, what size are you looking for?

    The drill doctor pro model allows you to sharpen split bits, the others below it don't. I have split cobalt bits (the hardest bit I've found in local hardware stores) and they only come in split tops.

    You can sharpen a split tip bit if you have a stone in good condition on a bench grinder. It does take some practice though. I do all my bits by hand...after a while you get a feel for it. The only problem with hand sharpening is if you get the bits center slightly off it will drill a slightly larger hole than it's size.

    For really accurate holes this could be a problem.

    The Drill Doctor sounds like it would return your investmant pretty quickly. It doesn't take long to rack up $110 worth of new drill bits!

    If you go the grinder route, you can purchase a Drill bit gauge that helps get the proper angle. You can go to a machine shop supply place for these. /forums/images/graemlins/thumb.gif

    How about one of these? I haven't used one, but it's cheap!
