Drill Doctor drill bit sharpener

[rweis]

I recently bought the Drill Doctor 750x (3/8" - 1/2") to sharpen bits I have collected over the years along with my "working" set.



Straight forward instructions, includes a video, easy to use. Bits are nice and sharp.

Does this mean you like it or hate it?

When you say that something is "the ****", that means you like it.



When you say that something is "****", you pretty much don't like it.

Well, I took my Drill Doctor sharpened bits down to the machine shop (auto parts store) and asked the head machinist what he thought about the sharpening pattern. I regular sharpened 3/32" - 1/4" and split point the 3/32" & 7/64" because they were the smallest and would be the hardest to get the split point right.



He used his magnifier on the first 6 or so and remarked the first 2 were split point (correct) and the pattern was nice and even throughout, nice semetry .



Works for me!

Dunno about the "Drill Doctor", but I've tried a few others over the years, and found I could get a better job just tying them to the rear of my truck with a rope, and dragging them on the pavement for 10 miles or so...

HOLY COW!



I can SEE why it does a better sharpening job than most! At $109-$129, it SHOULD!



Maybe I was expecting too much from the $9. 95 ones I tried... :-laf:-laf:-laf

They are expensive but they work real good, and almost never have to buy anymore bits. Even if you break them and there is a little left you can sharpen them.

Some years ago I used a bit sharpener, it was for a precision engraving machine, the sharpener was small enough to lift with one hand except it was bolted down, the stone was diamond impregnated. It had two settings, first to repair the edge the second to give the clearance for the cut. When I had my own business I'd buy the most expensive drills I could find, my labor was too expensive to use cheap drills. Most metal drilling drills were designed to be used in a drill press, for hand held portable drills, ask for the bits used in the sheet metal trade, such as cladding on metal buildings, they come 5 to a package, some call them stubbies as they are short to avoid breakage, they are designed to throw away when worn, but I found they could be resharpened by hand about three times. Can get quite a lot of service out of them, and they are very reasonable in cost.

Women and tools are similar that way.

Thanks FLynes and BPowers, us old guys don't always get it...

I've been hearing about the Drill Dr. for a while and wondered if it was worth it. I guess I'll have to check one out.

I hate to do something twice. I try real hard to "do it once, do it right".



I tried to hand sharpen some bits and totally screwed them up. I had to either buy new bits or sharpen the ones I had (have had since 1970 ie good steel). I decided to do it once and never have to look over my shoulder and say "gee, wish I had".



So, I did, it does, and I'm happy , but yes it is pricey.

Some years ago a machinist showed me how to sharpen drill bits, grind the cutting edge and keep your hand against the rest and in effect allow the drill bit to drop the portion you hold, in effect grinding a clearance. Difficult to explain but with the right technique can do a fairly good job, just find someone that can show you, very handy if drilling concrete for red-heads and such anchors and hitting re-bar in many holes, and the only grinder you have is a 7 inch angle grinder to sharpen the drill bits. (What! Construction Millwrights Over Paid? they are worth every Penny, so there!)

I also have a Drill Doctor & never had any problems with it. Does a good job of sharpening all size drill bits.

I like my Drill DR. Being able to apply a split point on a bit is nice, and having the ability to sharpen the last bit in the box that is the correct size but to dull to finish the job is priceless.

 

[Pavemen]

I love mine. Its the older 750 version (not the "x") and I've done 3/32" to 3/4", dull and broken bits, added split points, etc.

Works great and worth the money.

I have been thinking about the drill doctor for a very long time. After reading about you're guys input I am sold I will be buying one as soon as I can.

I purchased a 3/4 Drill Doctor a year ago to use in my home shop. It worked ok but it was slow, i could sharpen a drill on the bench grinder several times to one use of the D dr. I was hitting rebar in concreat. I took the loss and put it on E-Bay just to get rid of it. It was slow but the split point did look nice.
