Tools and Hardware Reviews of Drill Doctor DD750X Drill Bit Sharpener

Customer Review: 55# of dull bits + Drill Doctor + some sweat = magic!
Summary: 5 Stars

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!

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.
