More Information

● The DLC coating has excellent wear-resistant and welding-resistant properties that make it ideal for machining non-ferrous metals such as aluminum, copper, etc.
● A strong torsion shape provides superior discharge of cutting chips and cutting capability.
● Designed for very frequent drilling of pilot holes for M4 – M12 metric coarse thread.
● Two models of step angle are available for chamfering and cutting.
● High-efficiency hole drilling is achieved by reducing the chamfering process. (DLC-SC-SDR)
● When drilling pilot holes for bolts, relief holes can also be drilled at the same time. (DLC-SF-SDR)
