Sharp Tools Perform Better and Are Safer to Use

Sharpening dull and broken drill bits saves you time and money. View larger.
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.

Drill Doctor
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 250SP (Drill Doctor's Handyman model) sharpens conventional tipped bits and masonry bits from 3/32 to 1/2 inches in size at a 118-degree angle. It makes a great addition to a home shop and the do-it-yourselfer's toolbox. For people who need to be able to sharpen split-point bits or sharpen at a 135-degree angle, Drill Doctor's 500SP and 750SP models might be a better bet. Operation is fairly simple, but to make sure no one has trouble figuring it out, a how-to video is included. 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 -
