MAPAL
MAPAL has developed a step drill specially for the screw bores in the connecting rod with which the mass production of these parts can be made far more effective. The new step drill produces the screw bore in just one machining step. A special geometry, coating and edge preparation in combination with the four guide chamfers ensure optimum process reliability with very high performance and tool life. With a newly developed chip guiding stage (patent pending), a short spiral ship is produced at the countersink diameter that is freely discharged and cannot wrap around drill or chuck. In order to ensure process reliability and consistently good results in mass production, the drill was made from a special ductile carbide material in combination with a sturdy geometry and is ideally suited to the production of large quantities of connecting rods.
