For your own safety, please read this User's Guide before operating the Drill Doctor® . Do not wear loose clothing or jewelry; they can be caught in moving parts. Always disconnect the Drill Doctor® when cleaning, inspecting, and changing accessories, such as the diamond sharpening wheel. [. . . ] Identifying Correctly Sharpened Drill Bits (and what to do with those that aren't!To increase relief, insert the alignment guide on the chuck closer to the (+) side of the alignment port, then sharpen the bit. The entire surface from the Cutting Edge to the Heel will have a finely ground surface without ridges or indentations. Bit backing out or slipping out of the jaws when you are sharpening Chuck too loose or too much pressure when sharpening. Use more torque when tightening the Chuck or less pressure when sharpening. Realign the bit by carefully following steps 1 through 5 on Pages 8 to 10. Split point drill bits prevent walk-around on the material before they begin to cut. A standard drill bit chisel point has to wear an area in the middle of the hole to be drilled before the cutting edges will remove material. Due to its additional cutting lips along the chisel edge, a split point will begin cutting immediately. Up to 70% less thrust (when compared to a non-split or conventional point) is required to drill a hole with a split point. If the machine quits removing material before the chisel is clean, realign and sharpen again. Use the Chuck Knob to rotate the bit until it can be held by the Bit Clamp Arms in the narrowest width of the bit. Make sure that the bit is touching the Drill Stop, then release the Alignment Button. Turn the Chuck until the Alignment Guide on the Chuck aligns with the 118º notch on the Alignment Port. 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. Instead you insert the Chuck until it touches the wheel, remove, and repeat on the other side. It is important to sharpen these bits so that the entire face of the drill bit is sharpened. A large bit requires more pressure and will require more half-turns to sharpen it. 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. Both Models 500X and SB enable you to adjust the Chisel and Relief Angles of your drill bit. [. . . ] Firmly and slowly push the Chuck into the hole until the grinding sound stops. 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. The Sharpening Wheel supplied with the Drill Doctor is designed to give you long and trouble free service, with an average of more than 200 sharpenings for 3/32" to 1/2" drill bits. [. . . ]
