Spesifikasies
Produkbeskrywing
High-Speed Steel Performance: Constructed from M35 HSS with industrial coating for superior heat and wear resistance. The 60-63HRC hardness ensures durability in continuous drilling of stainless steel, alloy metals, and hardened plastics.
Precision Step Design: Engineered with 5 graduated steps (4-12mm) and 118° point angle for clean hole enlargement. Each step features an 8.2mm cutting edge and 1mm chamfer to minimize burrs during transitions.
Industrial-Grade Applications: Designed for CNC machines, automated production lines, and precision tooling. The 43mm cutting length and 64mm total length provide optimal stability for drilling thin metal sheets, electrical enclosures, and composite panels.
Enhanced Tool Longevity: The triangular shank ensures secure chuck gripping, while the spiral flutes facilitate efficient chip evacuation during high-speed operations.
Heavy-Duty Compatibility: Ideal for aerospace components, automotive parts fabrication, and industrial equipment maintenance. The coated surface reduces friction and extends tool life in abrasive materials.
