    I have the same drill grinder. It appears the bit holding gizmo is missing, without that it's useless for its dedicated purpose. I'll take a look, at one time I had an extra bit holder (the bit holders tend to get separated in auctions, etc).

    They're pretty fool proof. Very easy to use, about the easiest drill grinder I've ever seen. That model only does plain bits, no split points, I always wondered if a special holder could be made to split points. The company did make a more expensive version to grind split points. Any point angle is possible although I keep mine at 118 degrees. Sometimes in a pinch I lightly touch up a 135 degree split point, but only very lightly.

    The bit stays cool even at 5,000 rpm or whatever it turns at since the contact diameter is so small. The wheel seems to be self dressing. If a drill is broken off I rough the point on a bench grinder to save the special wheel for final sharpening.

    My local tool grinding business uses that grinder for regular bit sharpening.

      Apparently the company is still in business.... The bit holder sells for $245!!!! That seems like a lot, but it might be worth it since you already have the basic unit.

        I have a similar unit, mine's a JDR. Does a beautiful job. The bit holder on mine is actually pretty simple, I think a machinist could make one, it's aluminum.
