Web16 de jan. de 2024 · When drilling deep holes, a higher helix angle is necessary to pull the chips out but higher helix drill bits have narrower cores and are significantly weaker. … WebDifferent manufacturers will utilize different angles (i.e. 37° vs. 38° for HRSA materials). * Utilize a higher helix angle for free machining stainless steels and materials with lower machinability rate (more difficult to machine) such as Inconel, titanium, A286, etc. Summary. Using a higher helix when not necessary can reduce tool life; and using too low a helix …

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.
