Sharp Tools Perform Better and Are Safer to Use
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.

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.

(unedited original)
Wrecked a considerable pile of drill bits with this one. Mine went "ziiiiing-tick" instead of the "ziiiiiing" the video tells you it should sound like. Just a tiny tick, but since I've never even seen a drill doctor before, and not knowing the "tick" was evil, I continued on. First bits were OK, but got worse very quickly. The angle was getting worse and worse on every bit I sharpened. Which led me to believe I was doing it wrong... so I kept practicing and watching the video, and practicing for hours until most of my drill bits were short and wrecked. By that time, the "ziiiiing tick" was a "ziiing-TWACK", by the way.

Being the curious guy I am, I removed the guard and side plug and put a strong light in front so I could see exactly why it was wrecking my drill bits, what was I doing wrong? Well, I found the grinding wheel was not firmly held down by the spring loaded twist-on retainer. I don't know if the retainer wasn't put on properly by the factory, or if the spring wasn't seated correctly... all I can say is I could spin it with my finger at first, then it was tight after I removed it and reinstalled it)

Any way, the momentum of the wheel allowed it to start grinding each bit, then the wheel would stop in the mid turn of the drill bit, while the motor continued to turn full speed. It's quite loud, so there was no way to know this was going on without seeing it.

Upon receiving the Drill Dr., I immediately opened the box to find both an instruction manual and a DVD. The instruction manual is clear enough that, given you're already a "handy-person", a couple of reads is sufficient to get started. I have not opened the DVD. It takes ~20 minutes or so, after opening the box, to sharpen your first bit.

The process, as described, begins with an overview of the machine, chucking the drill, setting the depth of material removal, setting the angle of the grind, and determining if the grind was properly achieved. Afterwards, you can perform a 'split-point' operation if desired.

A few caveats. First, this is NOT a precision machine to be used for sharpening precision machine tools. Setting up the EXACT angle for grinding is difficult, and took me a few attempts. The two most common angles are 118-degrees and 135-degrees, for which the Drill Dr. has pre-set positions. Some of my drill bits are 130-degrees, made from HSS-Co. I suggest you start with a lesser drill bit that you can 'sacrifice' for the learning process. Second, during the sharpening process, you rotate the chuck (containing the drill bit) in the bushing that sets the angle. There is quite a bit of 'play' during this process, so it takes some care to ensure you are consistent during this operation. With more practice, it should not be a problem. Third, think twice before you do the 'split-point' operation. The radius of the split-point grind is OK for large drill bits, but will consume most of the drill-bit surface for anything under ~1/4-inch. Finally, it would be useful to have a rubber pad underneath the Drill Dr.. The grinding wheel is spinning ~20,000 RPM, and the Drill Dr. 'walks' across a hard surface.
