DLC Coated Carbide Stepped Drill for Aluminum Machining, Stub
Brand :
MISUMI
Caution
Product Description
[Features]
·Outstanding chip discharge and sharpness are demonstrated by high helix shape
·Designed for frequent pre-drilling of M4 to M12 metric coarse pilot hole
·2 types of step angles are available for chamfering and cutting
·Reduces chamfering process and achieves high-efficiency drilling. (DLC－SC－SDR)
·Relief holes can be processed at same time when drilling pilot holes for bolts (DLC－SF－SDR)

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)
