Does anyone use these and if so which one works best? Just can't help but think like every other cutting tool keeping them sharp they will work better, plus I have a pile of old dull bits laying around.

I doo a lot of drilling on my job. Bought a Drill-Doctor. Worth every dime I spent, around 100 bucks. Drill gets dull, sharpen it and go on. Love it.

I agree with Jake. I got the 500 model--I think it's the SX2. It's the one that'll let you split the points of bits.

I now think I would have been better off with the most expensive one (about $150 as opposed to about $100) because it's the only one that'll sharpen both bit tip angles.

I use the drill doctor as well. FANTASTIC! However, that NEW one they show on TV looks even better :musc:

I suc at drill doctor.... must be putting the bits in wrong ... come out almost flat ..

A good eye and a grinding wheel or unlimited supply of new drills are what I prefer. Flat bottom drills are tougher to grind so you are probably too far advanced for the drill doc, Ed.:hihi:

The angle is adjustable. Put the index on the chuck at 115 degrees not 135. Big difference. I was doing the same thing with my first tries.Then I read the instruction book:huh: . Now I get razor sharp bits every time.

Yes 118 degrees for softer regular drilling and 135 for the hard stuff like steels and such.

Thanks Fred/Jake .... I'll look ...
