Just not worth all of that for a sharp drill bit in my mind.
Hopefully not literally!

The "flame suit" comment is a perhaps a little in jest........I know this site would not put up with real abuse.
It's just this topic usually brings out the folks that say it's a death trap and will never be an acceptable way to use a grinder.
How close the nose of the tool is to the wheel is how you set the back rake and chisel angle, and is different for different helix angles.Those things do get "trashed" here quite regularly by the higher-end machinists.
However I just got one recently, and it works great!
I got it after a bunch of investigation. (I'll post a link if I can find it to a review of Drill Doctor vs. this type of sharpener)
The Drill Doctor was just not in the budget, and I believe this will serve me well.
The only problem I have is that I moved the sharpener base before measuring/marking the location after I found the "sweet spot". Now I need to go thru the "calibration" process again.....
Putting on my flame suit!

I have ground hundreds of drills on the side of one aluminum oxide 100 grit wheel, and if you looked at it you might guess someone tried to grind one drill on it. There is absolutely no visible 'wasp waist' on the wheel. It appears barely used. Cuts are kept light, no hogging, even on heavily damaged drill points. Hogging on the face of a wheel can also create grooves and explosions.Just a thought but wearing the wheel side and weakening the circumference be more of a problem than than simply the side load. I just recently set up the Craftsman version (US made by General I think) and placed min in the front. I've only used it on larger bits so far an thought they did a great job.
