Basic Angle of Twist Drill

The back Angle of the selected point on the twist drill's main cutting edge is represented by the feed back Angle αOm in the point column profile. The column profile is a straight line parallel to the Bit axis through the selected point M of the main cutting edge, which rotates around the Bit axis to form a cylindrical surface. The back Angle α at Twist Drill's outer circle is usually 8° ~ 10°, and the back Angle at the transverse edge is 20° ~ 25°. This can compensate for the effect of the actual working back Angle at each point on the main cutting edge decreased due to the axial feed movement of Twist Drill Bit Details, and can adapt to the change of rake Angle.
