[. . . ] It is sure to become a valuable tool because you will always have sharp drill bits before a project, during a project, and after a project. As president of this company, I am very proud of the quality of our products--and I am equally proud of the great people at Drill Doctor® who design and produce them.

Check the tip of the bit carefully to determine that both sides of the bit are split equally. If it does not match, study the information below. Split lines are joined in the center and Chisel Edge has been removed. The Grit Tube attachment is designed to keep any sparks caused by sharpening safely inside the machine and away from you. in addition , the Grit Tube reduces the sharpening dust in the air and on your workbench. Simply insert the Grit Tube into the Splitting Port of your Drill Doctor when sharpening. It will catch the grit that is formed from the sharpening process. Clean the inside of your Drill Doctor and the Grit Tube on a regular schedule. The grit tube is designed to accept a standard 1-1/4" shop vacuum for extended periods of sharpening. Split lines do not meet in the center but Chisel Edge remains. More grinding is needed for larger drill bits. If one side of the bit is undersplit, insert the Chuck into the Splitting Port again and split both sides. Push the Chuck into the Port until it stops. Repeat until the split sides are equal and look like the correctly split bit shown above. Not enough material has been removed from the Heel of the drill bit. Too many rotations of a small-diameter bit may result in incorrect sharpening and too few on a large bit may not sharpen enough. Continue to sharpen until the Chisel Edge is clean and straight and the entire surface from the Cutting Edges to the Heel is finely ground. To sharpen a masonry bit, you do not turn the chuck. Instead you insert the chuck until it touches the wheel, remove, and repeat on the other side. Insert the bit into the Chuck and line up the carbide insert on the tip of the bit so that it is parallel to the Masonry Sharpening Marks on the end of the chuck. Leave about 1/2"­5/8" of bit sticking out past the nose of the Chuck. [. . . ] Unplug your Drill Doctor, make sure machine is cool, then remove wheel cover. Use wrench supplied with your Drill Doctor to hold sharpening wheel in place. With compressed air, blow out the Chuck from the Knob end or brush out with a small, dry brush. You can double the life of the Diamond Sharpening Wheel by reversing it before you replace it. [. . . ]
