    2020-2-4 · A long guide, a short guide, and no guide were used with a drill press, a pneumatic drill, and a manual drill. Using a 2-mm drill bit, the overall average diameter was 2.03 mm and the overall range was 1.85 mm to 2.60 mm. Statistical analysis of the data indicates the drilling method and the guide length made no difference in the hole diameter at the 95% level (P = .05).

    When drilling, the drill bit or the workpiece rotates, the drill bit enters the workpiece, and the cutting edge drills. The main role at this time is the rake angle. Compared with the rake angle of the turning tool, the rake angle of the drill bit is diverse and complex, so the helix angle of the drill bit …

    For instance, if you have a 13mm (½”) chuck, you can get a reduced shank drill bit with a 16mm diameter and a 13mm shank. These bits can drill through wood, metal and plastics. If you decide to use a pilot drill first, the diameter of the pilot drill should not exceed 25% of the reduced shank bit’s diameter.
