Tungsten Carbide Twist Drill’s Helix Angle Impacting Drill’s Life

Due to tungsten carbide twist drill’s shape, the cutting edge features of each point shows the helix angle is changed, the tungsten carbide twist drill’s helix angle directly affects the anterior horn of the main cutting edge.

Tungsten carbide twist drill’s helix angle is larger, the more sharp edge, cutting more light, otherwise it will cause serious hardening phenomenon making the blade quickly wear. According to the relevant tool design data, taking tungsten carbide twist drill’s helix angle of 30 ° to meet the requirements, while allowing for mass production.
