Basic Angle of Twist Drill
β Helix Angle is the Angle between the most outer spiral line on the spiral groove of the Drill Bit and the axis of the Drill Bit after it expands into a straight line. Because the lead of each point on the spiral groove is the same, the spiral Angle of Twist Drill Bit Bunnings is different at different diameters. The spiral Angle is the largest at the outer diameter, and the smaller the spiral Angle is closer to the center. When the screw Angle increases, the rake Angle increases, which is beneficial to chip removal, but the bit stiffness decreases. The screw Angle of standard twist drill is 18° ~ 38°. For smaller diameter Twist Drill Bit Buy bits, the screw Angle should be set to a smaller value to ensure the Bit stiffness.
