Instead of throwing away old, dull bits, give them a checkup with the Drill Doctor and extend their life. Although drill-bit sharpening systems often fail to live up to our expectations, we're here to bear witness for the truth of the Drill Doctor's claims: it really does sharpen old bits in just a couple of minutes. The 750SP (also known as the Professional) works on conventional, split-point, and masonry bits from 3/32 to 3/4 inches in size. If you don't plan on sharpening anything larger than 1/2-inch bits, we recommend getting the 500SP instead; it's basically the same machine, minus the cost of the 3/4-inch chuck that comes with this model. Both models--the 500SP and the Professional 750SP--allow you to choose between a 118- and 135-degree sharpening angle. Operation is fairly simple, but to make sure no one has trouble figuring it out, the Drill Doctor comes with a how-to video. Anyone who frequently wears down drill bits is going to appreciate the savings this handy machine can offer. Using sharp bits instead of dull ones also increases the life of your drill, because sharper bits require less work to make the same hole. We only wish we'd found the Drill Doctor sooner. --Brian Trinen ... Read more

Drill Doctor DD750PK Precision Drill Bit Sharpene
There are many good things about this product. When I called tech support with a problem (chuck sticking), I got a human being with a knowledgable answer (loosen a few overtorqued screws) in a matter of minutes. On standard drill bits, it works very well.

However, I got it mostly to sharpen hex-base drill bits, as I use these drill bits with a quick-change chuck all the time. And I basically destroyed several bits (well, they were dull anyway) finding out that the chuck supplied with this unit simply can't get a proper grip on hex-base drill bits. They will be out of alignment, which means it won't work, at all. You just grind off random bits of your drill bit at random angles, resulting in a useless bit. Well, I _was_ able to sharpen a few of the bigger hex bits, but the 1/16", 1/8", and 3/16" bits were trashed.

So for my main use--sharpening hex-base bits--this fails pretty badly. If I'd known this, I wouldn't have gotten it. (Of course none of the marketing information or tech support information mentions this--if they did, they might lose some sales.) So I'll keep it, but quite disappointed. And no, tech support didn't have any suggestions for how to fix the problem.

So, if you want to sharpen small hex bits, give this a pass. If you don't use hex bits, it is a good deal. And the video they supply is excellent for teaching you how to use it.

Your mileage may vary.

The BEST Drill Sharpening System
Over the years I have collected hundreds of drill bits that served me well when new. But with each project I found myself looking for a sharp bit to complete the task. I needed a repeatable way to sharpen my drill bits. After extensive research and product reviews I purchased the Drill Doctor 750. It did EVERYTHING it promised. It sharpened both small and large bits, it removed all nicks and restored the cuting edge perfectly. The actual process is simple and quick. The video gives good instructions, but practice makes perfect, and I actually enjoyed sharpening all my old bits. I highly recommend the Drill Doctor. It delivers on its promise every time.

Pays for itself quickly
Glad I FINALLY bought one!
With the price of drill bits rising every day this baby will pay for itself quickly. Sharpens bit as good as or better than new. If you think you doing a good job sharpening bits on a bench grinder, you'll be suprised. Don't know how the hail I ever got along without one of these. Will never have to use a dull bit again. An absolute NECESSITY for anyone working with steel. I would suggest getting an extra wheel upon purchase because once you sharpen about 250 of your dead/dull bits after it arrives, you'll most likely need a new wheel.

The Good, the bad, and the great
I just received my Drill Doctor 750SPK and was surprised to find that it came with a carrying case which was listed by Amazon.com as an accessory. The first time I used the Drill Doctor it performed perfectly and I was inclined to sharpen even drills that I had previously considered sharp. For normal drill sharpening, I would rate it as 5-star. The only problem I had was with split tips. The drill holder does not slide smoothly in and out of the guide. It requires unnecessay force as far as I am concerned, however with extra effort I can sharpen split tips adequately. I will keep the unit since most of my sharpening is for standard tips. When and if I want to do many split tips, I will bore the guide out a little and and install a "pop-out" spring to move the tip back off the grinding wheel.

Incidently, one reviewer said that he received screwdriver tips instead of drills with his unit. I did not find that to be the case. I received the drills.

NO MORE DULL Excuses!!
This is product is everything good all have said about it. Order fulfill by Amazon - excellent! Unit well packed, handy carry case is superb.
Set up and use - I watched the video 1 & 1 1/2 times. Getting the drill set up properly is the whole equation - and is easy. I have sharpened both angle configurations, and split a few points just to see how easy it is to do. SNAP!
I didn't realize how bad a shape I was in until I cleaned up every bit I owned. I mostly work wood and don't demand a lot of twist drills here, but a few metal things came up and I realized I had a sour batch of drills. Problems solved. Everyone needs one of these....or maybe I keep it a secret and make a few $$ fixing up my neighbors tools. It would almost be like stealing. Maybe I'll do demo's and sell units. ... Read more

Drill bit savior
I used to throw out bits when they were dull. Never again! This tool is really simple to set up and use. I hate to think about the time I've wasted using dull bits. It takes just seconds to touch up a bit. My friends now ask me to sharpen their bits. I wish I had had a Drill Doctor ten years ago.

Nothing else comes close
I don't know how many broken or dull bits I have sitting around because up to now it has been one big pain in neck to resharpen them. I usually wind up buying a whole pack (10) of the most popular sizes I use and set them aside after they get dull. I have several different drill sharpeners; you know the type one would use with a grinder. Problem is they have never worked well for me, it seems like it's always hit or miss and most of the time "miss seems to prevail" and setting the jig up for sharpening the bits was always a chore. So it was with some trepidation I bought the Drill Doctor" especially because it was a lot more than I had ever paid for any other sharpener. But this is truly a case of "you get what you pay for...sometimes). But after reading the reviews I bit the bullet and ordered one. Gotta tell ya...I am now one happy camper when it comes to sharpening my old dull bits. It works just like the provided video shows, not just once but each and every time! Anyone who can't sharpen a bit properly with the Drill Doctor probably shouldn't be handling a power tool in the first place. I mean it is virtually moron proof. Loosely calculating the number of useless drill bits I have accumulated over the years I figure this tool will more than pay for itself. Looking for the right tool to sharpen your drill bits?...Buy the Drill Doctor, I promise you will never look back.
Oh by the way, a little background on me. I am a retired General Contractor and an active hobbyist. I own 6 cordless drills, 3 corded drills, and 2 drill presses (what can I say I have a weakness for good tools!) so I guess it would be fair to say I have had some experience working with drills and drill bits.

The Handyman's Money Saver
This is a great investment to help save money from buying extra drill bits when all they need is re-sharpened. I wish I had this product when I first started using drill bits. It comes with an instruction book & a VCR tape which helps to learn how to sharpen drill bits in almost no time. Just think of all the extra trips to the store this product will save you from?
If you happen to break a drill bit, just use this to put on another new tip. This model sharpens either of the 2 major angles for steel bits, plus split points and also mason bits.

NEWS
I have used this product in the past and found it to be very useful. I'm very discouraged in hearing that the new machines will be manufactured in China. I guess this is another example of companies concerned with profit margins and not quality. I will stock up on replacement wheels now to avoid future disappointments.

Seems to do what it says.
Used my drill doctor for the first time yesterday, seems to be pretty straight forward. Only a couple of things I could see after using it that would greatly improve it. First the electrical cord should be made of rubber, mine in my unheated shop, in MN, is like a slinky toy and came unplugged a couple of times. Next a light in the depth and alighning hole, my eyes aren't what they used to be and my shop isn't bright for close work during the waning hours of the day. Other than these two suggestions it seems to work ok and is going to be handy to have around. ... Read more

The very best on the market
Ordered this from the drill doctor and they sent me to amazon to buy it at a cheaper price. I don't know of another company that would do this for a customer. Now thats what I call a five star rating. I would do business with this company it they only sold horse shoe nails.

Drill Doctor Saves Me Hundreds of Dollars!
I've been burning through drills since my father let me in his workshop @ age ten. Since then I had buckets of used drill bits that were just worn out from high use. My idea was that someday I would find the time to sharpen them. I came across the Darex Drill Doctor Model 750 @ a local farm show. I have been skeptical of these sharpeners before because I have been burned by a PlasPlugs model that said it could sharpen drill bits. After seeing a demonstration firsthand I purchased the Drill Doctor 750 because I needed to sharpen the larger and more expensive 3/4 inch drills. The return on my investment was made within the first couple of hours using my Drill Doctor. The best thing about it is that I can sharpen 118 & 135 degree bits and put a split-point on them! Their diamond wheel lets me sharpen all kinds of different drill types.

Finally a drillbit sharpener that WORKS!
I was skeptical that the Darex 750SP wondering if it was just another gizmo that was "supposed to" sharpen drillbits. After calling the manufacturer to find out if they could convince me that that their product would produce consistant "professional results" I was convinced enough to give it a try. What I found is that it works VERY well even on the smallest bits. Bits in the 3/8" to 1/2" range take a little more time to sharpen due to the amount of material being removed, but any bit less than 3/8" can be ground razor sharp in less than a minute... and most in 30 seconds or less! The sharpener has more than paid for itself since I have sharpened a few hundred bits in a wide range of sizes. With the Darex 750SP I am able to take dull or even broken bits and make them as sharp or sharper than new. And with new bits at $1.50 to $3.50 apiece, it didn't take long for the tool to pay for itself. ... Read more

Worked as advertised
I bought the Drill Doctor 100 travelor, and it has worked real well for me. Since I bought it I've sharpened a dozen worn out bits and already made my money back. The sharpener helped me fix up my garage and saved me alot of money and time. Saves me the problem of buying new bits every few months. Highly reccomended.

Save your money!
This thing is a toy. You would be far ahead if you spent the $bucks on a new set of drill bits. It comes with six little paper sanding rings. Maybe you could sharpen 2 bits with each one if you wanted to waste the 30 mins on each drill bit. I PLAYED with the toy for about an hour and the drill bit still wasn't sharp. ... Read more

Drill Doctor 250SP fixes my bits
This is a nice product, I'd almost give it 5 stars but its not perfect.

I almost bought one a year ago, but I decided to get a bench grinder instead thinking I could sharpen my bits that way. Well, I was able to sharpen some but the learning curve was a little too high. You have to use a twist and feed motion to cut the right curve in the bit at the right place. My sharpened bits were time consuming to get uniform and just right.

The Drill Doctor I finally got recently makes it a snap - the set-up alignment is nearly fool proof and the chuck rides a cam to get the correct feeding motion everytime. I sharpened all my bits (three or four sets plus the ones in my tap set) in less than an hour. All looked sharp and uniform. I read the two page instructions and bagged the videotape it was so easy.

My complaints: Won't do bits under 3/32", the smaller bits are hard to align because they are short and hard to grab and twist, and as good as it is, I wish it didn't cost so much.

Hint: on those short bits, I just learned to insert then in the aligner first, turn to the correct orientation, then slide the chuck over them and tighten the chuck.

The best little drill bit sharpener ever
The Drill Doctor 250 is a must for all tool enthusiasts. Sharpening twist and masonry bits has never been easier. The instructional video (included) is a definite prerequisite to using the Drill Doctor. It sharpens bits beyond their original factory edges, and for under a $100 bucks it was an easy purchase compared to ruining bit after bit on my bench grinder or buying new bits all the time. The 250 is one great tool.

What It Does It Does Well
My wife gave me a Drill Dr. 250SP a couple of Christmases ago, and I wouldn't be without it. If you often use twist bits and masonry bits it's fantastic.

I viewed the videotape and read the manual before I even plugged the thing in. You really need to do this in order to understand the tool and use it successfully. The instructions were well conveyed--in fact even a bit redundant.

Once I got my mitts on the tool, I found it to be well made with heavy plastic case and high-grade cord. It looks like it will last a long time, and it sounds like a quality tool when it runs. It is also easy to use, sharpening efficiently and smoothly with very little practice. I was able to sharpen about 72 bits in my shop in a little over an hour.

A sharp bit makes much cleaner holes in wood with no burning. And I often use it to sharpen bits right before I drill metal--always makes a cleaner, faster cut and the bit doesn't dance as much when you're starting the hole.

I don't have any problems sharpening 1/8" bits, but smaller than that, I just use bits like consumables because they are so cheap.

The point has been made that what the DD costs will buy a lot of bits. That may be true if you buy cheap bits, but would you buy a new bit for every project? And what about your time to go to the store to pick the darn things up?

True it doesn't sharpen brad point bits, impact bits, Forstner bits, auger bits, saw blades, jointer knives or fingernail clippers, but what it does it does very well at a very fair price.

Two big thumbs up!

Great Tool
This is a great tool for sharpening small to medium size drill bits. It really does work. Larger bits take take a while to sharpen and it does get tedious having to turn the bit while using the drill to spin the sharpening abrasive. It would have been cool if everthing was automatic but then look at the low price. Overall this is a great tool...you can have your old bit good as new in just 3-5 minutes.

Great Sharpner-Great Price!
The Drill Doctor 250 is one of those few products that deliver performance exactly as advertised! I was able to restore 40 or so dull bits collected over the years (personal problem throwing junk away)! The 250 gave the bits balanced, sharp cutting flukes that hold up well. The new cutting edges have extended life to my cordless drills batteries and reduced project times due to greater efficiency in drilling operations. The video and operation materials are real straight forward and easy to understand.

I've used several power tool bit sharpeners, including the old B & D industrial units. They all worked well but at 3 to 4 times the price. Darex has produced a quality product at a real value price for the consumer. ... Read more
