The relief angle of the selected point on the main cutting edge of the Twist Drill is represented by the feed relief angle αOm in the column section at this point. The column profile is a straight line parallel to the axis of the Drill Bit through the selected point m of the main cutting edge, and the cylindrical surface formed by the rotation of the straight line around the axis of the drill bit. αOm also varies along the main cutting edge, and the closer to the center αOm is. The relief angle α at the outer circle of the twist drill is usually 8° to 10°, and the relief angle at the Chisel edge is 20° to 25°. This can make up for the influence of the reduction of the actual working clearance angle of each point on the main cutting edge due to the axial feed movement of the drill bit, and can adapt to the change of the rake angle.
