AAC01 TLY M42 HSS Cobalt 8% Drill Bit

. Material: Made of premium M42 High-Speed Steel with 8% Cobalt (HSS-Co8). This alloy achieves an ultra-high hardness of HRC 64-67, offering superior heat resistance (red hardness). It maintains a sharp cutting edge at high temperatures, lasting 10X longer than standard HSS bits when drilling abrasive materials.
 
. Craftsmanship: The drill bit is Fully Ground from solid hardened bars to meet strict DIN338 standards for precision. It features a professional 135° Split Point tip that ensures instant self-centering. This design prevents the bit from "walking" on the workpiece surface, eliminating the need for a pre-drilled pilot hole or center punch.
 
. Function: Specifically engineered for high-tensile strength metals. It cuts through Stainless Steel (Inox), Cast Iron, Titanium Alloys, and Hardened Steel effortlessly. T
 
. Usage: Universal Straight Shank fits all cordless drills, drill presses, and CNC machining centers.
