The second side of the bit is now split. www. DrillDoctor. com 2. 3. 10 4. 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. Identifying Correctly Split Drill Bits (And What to Do With Those That Aren't!) Correctly Split Split lines are nearly straight across. Split line Undersplit Split lines do not meet in the center but Chisel Edge remains. Solution More grinding is needed for larger drill bits. If one side of the bit is undersplit, insert the Chuck into the Splitting Hole again and split both sides. Push the Chuck into the Hole 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. Oversplit Too much material removed.

Question: When I aligned the drill bit and sharpened it, why was no material removed? Answer: This happens when the bit is not protruding out of the Chuck far enough. You may have allowed the Alignment Button to knock the drill back into the Chuck when aligning the bit. Carefully realign the bit in the Alignment Hole again. Make sure the drill is pushed all the way against the Drill Stop before you release the Alignment Button. 2. Why will it not cut? Answer: This happens when the heel on the bit is higher than the cutting edge (negative relief). Realign the drill and resharpen in the Sharpening Hole. Maintain consistent inward light pressure during the half-turns of the Chuck. Slow and Fast Spiral, Helix, Turbo Flutes, and Raised Margin drill bits are considered specialty bits. [. . . ] Sharpened drill bits burn or turn blue no matter how fast or slow you rotate the chuck. When touching the sharpening wheel (with the machine disconnected), the lower portion feels too smooth (nonabrasive). When sharpening the drill bit, it takes too many halfrotations to sharpen. If you sharpen only 3/32" to 1/2" bits, you can double the life of the diamond wheel by reversing it. [. . . ]
