Query: Drill Doctor 750p

it works as advertised, seems well made and the learning curve is short. Time will tell as to its quality. I sharpened 60-70 drill bits the first day i received it . most were 3/16" to 1/2 ".yep! they're razor sharp. the smaller ones were broken and tossed years ago. my point is, if i can keep them sharp for drilling metals, i feel the smaller bits will be less prone to breakage. a shop vac hose placed near the split point opening will keep airborne debris to a minimun when sharpening. reading the great reviews here is why i decided to purchase the 750sp
