Drill Doctor DD500X Drill Bit Sharpener

Not that much good as expected

Parfait attention c est en 110 v

I had a Drill Doctor 350 which was ok but it could only sharpen an angle of 118. I drill a lot of metal and 135 is a better angle for this material. I upgraded to the 500 and WOW am I ever impressed. The 500 can sharpen both angles and do it well. There’s not big learning curve either. There’s a video on using it as well as a pretty good manual included. I honestly don’t think I’ll ever need to any new bits for quite some time.

If you're looking to be able to ram your bit through the grinding wheel as fast as you can, don't get this. If you're more in tune with the current universe, read on. I've bought a couple of these, though not because the first one wore out! This should be the last drill bit sharpener you buy IF you take care of it and actually read the instructions. Very inexpensive considering no more drill bit purchases (unless you just break them). It IS often possible to sharpen a broken bit back into use if there is enough of the bit left. I have used this sharpener to do that several times. Use this on my high speed steel as well as Cobalt bits that have a standard shank. Always take any burrs off of the bit shank when sharpening. Is important to not rush or overload, then all is fine. Gives great results when used correctly. Doesn't need an "install" schmamazon getting its nose out of joint again. Plenty durable when not pushed too hard. Easy to get new stones and parts for. Good documentation. Great value for the money. The size is as stated again, schmamazon, wtf? Accuracy, well, I do not have the lab to be able to measure this but I CAN say the sharpened bits DO cut very much cleaner and faster! So empirically this works well! Never sharpen a bit so fast that it turns blue, or it is ruined. Never drill until it is blue either for the same reason. Never use the "hammer" mode on your drill using steel or cobalt drill bits or you will ruin them and possibly injure yourself. Use ONLY carbide tipped bits designed for hammer drilling with this function. This sharpener has a diamond wheel so it CAN sharpen carbide tipped bits!
