Using a grinder is an art form these days!
We have a guy at the store who does all the sharpening, cuts down keys, even trims down screen door frames, all with the grinder.

I got the 750x at a after Christmas sale last year at Sears for $99.99.

I know what your saying Larry and Jeff about the grinder. My dad can sharpen bits with a grinder, but every time I try to sharpen with a grinder the bit winds up in the garbage can. Usaully about a inch shorter than it was to began with.

:rofl: :rofl: :rofl: Me too!!

I will have one of these by the end of the day!

Good way to think!
The only thing worse than needing a tool and not buying it, is to find that you have paid for it and don’t have it.

Hey Bill,...........forgot to mention I usually wind up with band-aids on atleast 7 of my 10 fingers when trying to sharpen with grinder.

:toast: :rofl: That's why it's a drill DOCTOR.

The only problem I've run into with it is the long flexible bits don't line up very easy. Other than that it's great.

I cut my finger once on the cutting wheel of the key machine. Luckily it wasn't bad because that thing is SHARP!

I have the DD750 which appears to have been replaced with the DD750X. They both do bits up to 3/4" but the one I have will only do either a 118 or 135 degree pitch. The new model is now adjustable from 115 to 140 degrees.

The problem is that's still not an aggressive enough angle for installer bits. I use flex bits and most of them have a pitch of 90 degrees or less.

I had a few broken bits that I had "nothing to lose" so I sharpened them at 118. They just don't "dig" in and tend to wander too much at this angle (which is needed on a flex type bit).

I think the Drill Doctor is good for resharpening a drill index (universal wood/metal bits) but it's not good for any type of installer bit.
