Insert the Chuck into the Splitting Hole so the flat spots match (white line to white line) and push slowly and firmly until the Chuck stops (you will hear a grinding sound).

Split line Undersplit Split lines do not meet in the center but Chisel Edge remains. Solution More grinding is needed for larger drill bits.

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. 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). 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. Check the position of the two Flats on the Chuck and draw an imaginary line Heel from the middle of the flat up through the drill bit (3/32" to 1/2"). When aligning, start with the Bit Flat Spot Clamps on the narrow part of the bit, then turn the bit clockwise to approximately the 1:00 o'clock position. You may have to move the drill bit clockwise in the Chuck more than once until it sharpens correctly. If the chisel edge moves too far to the right, realign the bit and adjust again. 14 www.
