Processing effect
Twist Drill front and after the Tool surface are curved, along the main cutting edge of each point of the front Angle, the back Angle is not the same, HSS Twist Drill Bit horizontal edge of the front Angle of -55°. Poor cutting conditions; The distribution along the cutting edge is not reasonable, and the cutting speed of the tip with the lowest strength is the largest, so the wear is serious. Therefore, Twist Drill Bit Hss machining hole accuracy is low. The full cutting edge of the main cutting edge of the Drill participates in cutting, and the cutting Speed of each point on the edge is not equal, which is easy to form spiral chip, chip removal is difficult. Therefore, the chip and the hole wall extrusion friction, often scratch the hole wall, the surface roughness after processing is very low.
