Whether you're a professional tradesperson or a serious hobbyist, you know that a dull drill bit can waste valuable time, result in lower-quality work, damage work materials, and shorten your drill’s life. But unlike the relatively straightforward task of sharpening flat blades, sharpening drill bits by hand is a cumbersome and difficult task. This is what makes the intuitive, easy-to-use Drill Doctor sharpener so useful. Three Easy Steps Ensure Bits Are Sharp and Effective
With the Drill Doctor 750X, you simply align the bit by setting it against the stop and locking it in place. To sharpen the bit, you turn the chuck an even number of half turns, depending on the size of your bit. As you sharpen, long jaws hold the bit precisely in place, and jaw guides eliminate jaw twisting on small bits. This secure alignment system ensures that you maintain accurate bit geometry and don't damage the integrity of your tools. Once the bit is sharpened, the Drill Doctor 750X gives you the option of making a unique BACK-CUT split-point bit that gives your bit an extra-narrow chisel point, making it faster to penetrate and less likely to wander on the material you are drilling in to. Additionally, the drill point splitting port offers a "Push to Stop" design that will prevent over-splitting the bit point. The adjustable material take-off allows you to change the amount of bit material that is removed to accommodate large, broken bits or extend the life of small, precision tools. Engineered for Versatility and Flexibility
The same chuck can be used to sharpen bits of all sizes, from 3/32- to 3/4-inch, whether they are English, metric, or letter gauge bits. The Drill Doctor 750X sharpens a wide variety of bit types, from high-speed steel, carbide, cobalt, TiN-coated, masonry, and split-point bits for working with metal. Professional Design and Construction for Durability
For added durability, the Drill Doctor 750X features a metal split-point port and a die-cast point angle shuttle. The tool relies on a permanent-magnet motor that produces consistent power, regardless of speed or load. The Drill Doctor 750X also relies on an industrial-strength diamond sharpening wheel that won't change shape over time, and a cool design that means bits don't heat up and lose their tempering as you sharpen them. This wheel, which is good for about 200 sharpenings, is easy for users to replace. As a bonus, the Drill Doctor 750X comes with a rugged shell case, making it easy to transport to the job site. This durable case offers internal storage space for your Drill Doctor, two chucks, two sharpening wheels, and a storage area for small drill bits or other accessories. The Drill Doctor is backed by a three-year manufacturer’s warranty. What's in the Box
Drill bit sharpener, hard-shell carrying case, user guide, and instructional DVD.

 Drill Doctor 750SP Drill Bit Sharpener August 14, 2002
219 out of 226 found this review helpful
Wow, a drill bit sharpener that actually does as the manufacturer claims. To me, few things are more aggravating than trying to work with a dull drill bit, especially when working with steel. When considering the amount of time wasted and productivity lost whenever good sharp bits are needed on a job, but unavailable, it doesn't take long to realize that it only makes good economic sense to be able to sharpen your own bits, especially for contractors and service/maintenance shops. Personally, I don't mind spending a few minutes of my time, sharpening my drill bits, which I use on my jobs.
Like others, I had tried some of the useless, piece of junk sharpeners that came along in previous years and was a little apprehensive about trying yet another one. I'm glad I decided to try the 750SP. It really does have the ability to get your twist drill bits razor sharp, usually in less than one minute. You can also use it to convert standard point bits to split point bits. I thought it was going to be a pain to use, but the sharpening technique is simple and very easy to master. Alignment of bits over 1/8" is done with the chuck by inserting it with the bit into the alignment slot. With bits smaller than 1/8", you have to insert the bits into the alignment slot without the chuck initially and then slide the chuck over the bit after. This may sound a little cumbersome, but once you have the unit and do it one time, you'll see that is actually not an issue at all, even with bits as small as 3/32".
Watch the included video a couple of times, which is only about sixteen minutes in length, then read through the instruction manual and it will all come together.
The first bits I sharpened were 3/16" x 4", ¼" x 4" and ½" x 6" Relton percussion masonry bits. Now they are sharper than when new.
After sharpening, the tips of carbide masonry bits seem to have a more angular look than the original tip, but they work excellent. Refurbishing these first few bits saved about eleven dollars in replacement costs minus about six minutes of my time from start to finish.
I then continued on, sharpening my Hanson 29 pc. HSS set, a couple of Vermont American 13 pc. HSS sets and a box of various sized loose HSS bits. Most bits took well under one minute to complete, and I wasn't even hurrying. Almost all came out right on the first try. Any mishaps where easily fixed by simply repeating the procedure over again.
As for savings, the 29 pc. set cost eighty dollars new, the 13 pc. sets were fifteen dollars each and there where at least thirty dollars worth of loose bits in the box. That's about one hundred forty dollars of bits refurbished, minus around thirty minutes of my time. Keep in mind that this is only the first sharpening. It's safe to say that most bits in reasonably good shape can probably be sharpened at least eight to ten times.
One of the biggest and probably the most overlooked advantages of the 750SP is that it can also sharpen up to ¾" SDS type masonry bits. I used it to sharpen a small Bosch 5/32" x 4" [2"usable length], ¼" x 6" and ½" x 6" SDS bits. They are now good as new. I could never get them this sharp with just a file. This is about seventeen dollars worth of refurbished SDS bits and the sharpening process consumed all of about four minutes of my time. When you start getting into quality SDS bits sized ½" x 10" to ¾" x 10", then your beginning to look at real savings, with replacement costs at around sixteen to twenty two dollars per bit.
My 5/16" x 18" and 3/8" x 18" bell hanger bits required two hands to steady and guide them while sharpening, but they all came out great and haven't been this sharp since the day I bought them. As you can see, it just goes on and on.
The 750SP's comes with a carry case and the motor only draws 1.75Amps at 120V, so if you have an inverter in your truck, you can take it with you to the job and never have to worry about having anything less than the sharpest bit available. Supposedly you can get about two hundred sharpenings from one grinding wheel. Replacements grinding wheels cost twenty dollars and come in 100 grit or the standard 180 grit.
I have absolutely no problem at all recommending the 750SP. It works extremely well and requires a minimal learning curve. If you are concerned about return on investment, I think you will easily see the 750SP and any replacement grinding wheels pay for themselves in short order by refurbishing your more expensive SDS masonry bits and quality HSS or cobalt twist drill bits. Additionally, having sharp drill bits readily available can go a long way toward helping reduce job productivity losses.
I never though sharpening drill bits could be so easy! September 29, 2000

I never thought that sharpening my drill bits could be so easy! Not only does this machine sharpen my conventional bits with complete accuracy, but it will also turn them into split point bits if I so desire. And I don't even have to worry about getting the correct angle on the point! It is definitely a tool worth buying.

One of the best products I've found in a long time.. Very easy to set up and it does such a quick job that after you get all your bits sharpened you want to out and dull some so you can do it again!! The drill doctor is very easy to set up and use.. a little technique sensitive on small (less than 1/8 inch), short (contractor length) bits but very forgiving of mistakes. Just rechuck and resharpen. Small bits are a bit tough to set up, but as cheap as they are, I don't think I will bother. The big value is in the larger sizes that are more expensive. My biggest dissapointment was expected wheel life, 200 sharpenings - more or less. At $20 a wheel that figures out to ten cents a sharpening without amortizing the cost of the unit. The book says you can invert the wheel wheel when it gets dull but that still is 5 cents per sharpening plus time. On the other hand, I have converted relative inexpensive 118 degree standard bits into 135 degree split bits in a matter of minutes.
Botom line though, is, this is a product that fills a need very well and is very easy to use.
You will never throw another bit away. April 24, 2003

In short, you can sharpen all kinds of bits with this. It takes a little practice, and you have to watch the video, but once you master it, it wil be your friend forever. The local Sears has it for a little more, but they cary the replacement diamond dusted wheeel in case you ruin yours by not watching the video and thinking you know it all. This is one find product that you won't regret buying if you use a lot of drill bits. It will pay for itself by the cost of every bit that you do not throw away for the rest of your life. Don't loan it out, it takes know-how to use it properly, and the wheel can be ruined by someone who doesn't know what they are doing. Watch the video before you try to use it, not after you ruin the wheel. It is a $25 lesson; take the free lesson on the included VCR tape first.
55# of dull bits + Drill Doctor + some sweat = magic! December 5, 2001

[I own the 750SPK model] If you're like me, you have dozens (or maybe hundreds) of dull or broken drill bits hiding in the bottom of every shop drawer, tool box, and drywall bucket. Plus, they're under the workbench, behind the workbench, on the window sill... well, you get the idea. I got me one of these here Drill Doctors (sharpens up to 3/4" drills), and all my "sick" drill bits are now SHARP and healthy!!I don't know how Darex did it, but they have come up with a WINNER. I first sharpened all my small dull bits, then I sharpend all my Silver & Deming bits, -- through 3/4" -- then I sharpened all my BROKEN bits, and then I went back and made ALL of my twist bits into high-performance split-point metal eaters!! I am VERY happy with my machine. I have to admit though, that it took me quite a long time to figure out how to use it correctly. I recommend spending lots of time with their excellent video. I watched it MANY times, with the machine in my lap so that I could follow along, and then I sharpened a few bits, then studied the video again... Now I can sharpen even a really messed-up bit with my eyes closed. SERIOUSLY! The diamond wheel in this machine lasts and lasts, but like any good machine, if you push it too hard, it's not going to last, and your bits will not be sharpened as well as they could be if you let the machine do its work. I offer the following tips as well: I recommend that you clean your machine THROUGHLY after each one-half hour of sharpening. If you don't you will surely reduce the life of your machine, and worse yet, lose the accuracy you paid for. The grindings are very abrasive. I blast mine with dry air from my air compressor. Works slick. If you don't have a compressor, use the canned air sold to clean computers at any office supply store. And, if your lungs are important to you, wear a mask suitable for sanding wood. I used my Drill Doctor at the dining room table one evening, and the next morning, my wife showed me how much dust was all over the table. Later that day, I started coughing, and I got a nasty lung infection. Did the sharpener dust cause it? I think it may have! So, do yourself a favor and wear a mask. One last tip: If you plan to grind a "split point" in you bits, do it right after you sharpen the bit while it is still in the holder. I didn't at first, and wasted time on each one re-setting the bit to grind the split point. Darex makes drill sharpening machine used by machine shops and factories all over the world, so they really know what they are doing! When I realized how easily I can sharpen bits, I went to our local St. Vincent DePaul thrift store, and for $4.00, I bought 20 pounds of old drill bits. Guess what? They are no longer dull (or broken) (or sharpened WRONG)... now I have a couple hundred dollars worth of Silver & Demming bits nice and sharp. (S&D bits drill holes larger than 1/2", and their shank is turned-down to fit in a 1/2" drill chuck). I can now drill a hole (in the 1/2" capacity chuck of my drill press) from 3/32" up to a full 3/4" by 64ths.! I hope you are as happy with your Drill Doctor as I am mine. Happy Sharpening!
