  • Page 18: Split Points

    Split Points Split point drill bits prevent walking on the material before they begin to cut. This feature is described as self-centering. The need to center punch is effectively eliminated. 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.

  • Page 25: Questions And Answers

    Questions and Answers 1. Question: Why was my drill bit sharpened improperly? Answer: The most common cause of improper sharpening is improper drill bit alignment. Key causes are: • Chuck not inserted into the Sharpening Port correctly. Ensure the Alignment Guides (raised fins) are fitted into the correct alignment slot.
  • Page 26 4. Question: What can I do about flat spots on the bit point between the Cutting Edge and the Heel? Answer: The flat spots on a sharpened bit are the result of an incomplete or paused half-turn of the Chuck in the Sharpening Port. To correct, apply light, inward pressure and rotate the Chuck smoothly while sharpening.
  • Page 27 7. Question: Why is my split point uneven? Answer: You may have used uneven pressure during the splitting process. To correct an uneven point split, insert the Chuck into the Split- ting Port and split both sides again. Repeat until the split sides are equal.
