WebJan 14, 2024 · The most common chamfer angles are 82° and 90°, but most screws have an angle 82° so that is the angle that should be used in most projects. Countersinks are available with cones shaped to create six distinct chamfer angles — 60°, 82°, 90°, 100°, 110° and 120° — designed to match a particular screw’s head angle. WebMar 15, 2024 · The countersink depth is 0.358 m when the diameter is 0.55 meters and the angle is 75°. We can determine the depth using a simple formula: depth = (diameter/2) / … hisoka auto
