WebA drill bit with a low helix angle (30-36 deg.) does not evacuate swarf smoothly, causing roughness. Higher helix angle (40 - 45deg.) Large margin length. Increased area of contact between the drill bit surface and the hole wall raises drilling temperature causing roughness. Smaller margin width. Unsuitable tungsten carbide material.
