[. . . ] 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. Align one of the Sharpening Guides on the Chuck (short white marks) with the Splitting Guide on the Splitting Port. Make sure the Alignment Guides insert into the Split Point Guide Rails in the Splitting Port. Split lines do not meet in the center but Chisel Edge remains. Not enough material has been removed from the Heel of the drill bit. Press Chuck slowly and firmly into the Splitting Port until it stops. remove the chuck , rotate one-half turn , and repeat. 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 following. Split lines are joined in the center and Chisel Edge has been removed. Reinsert the chucked bit into the Sharpening Port and remove enough of the tip until the split tip looks like the correctly split bit above. 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" shop vacuum for extended periods of sharpening. It may take two or three complete sharpenings (repeat all steps) to resharpen a very dull or chipped large drill bit. Your Drill Doctor is delivered with a 180-grit Diamond Sharpening Wheel. If you regularly sharpen larger bits between 1/2" and 3/4", you may wish to purchase the coarser 100-grit Diamond Sharpening Wheel, which sharpens larger bits faster. [. . . ] Grinding particles will promote wear in the Sharpening Port and Chuck, so cleaning on a consistent basis can add life to your machine. Before any maintenance or cleaning is performed, be sure to disconnect your Drill Doctor. With the Drill Doctor unplugged, use your nail or the tip of your finger to pull the Wheel Access Cover down. It will come completely off for easy access. [. . . ]
