HF Drill Bit Sharpener

[gabkwong]

Is it worth the money to get this from HF? All my drill bits are destroyed because I don't know to use cutting oil when drilling metal!

Drill Doctor is supposed to be the good one.

I use the Drill doctor at work and it does an excellent job, but it costs a lot more than the HF model. I suspect that a standard bench grinder with a good grinding wheel would do just as good as the HF model.

You can do it with a bench grinder if you get the angle right. gabkwong, go buy the thing and tell us how it works. Once you figure it out, I'll bring you all my dull drill bits.
