About this item
- ★ Drill Bit Size --- Cutting edge diameter: 31.5mm; shank diameter: 1/2"; cutting edge length: 76.2mm / 3"; overall length: 152.4mm / 6", Included: 1 Piece x Drill Bit
- ★PRACTICAL PERFORMANCE --- The drill bit strikes a perfect balance between cost-efficiency and performance, featuring excellent machinability for general-purpose applications in normal working conditions.
- ★ Wide Applications --- For acrylic, plastic, wood, soft metals (Cu, Al alloys), commonly used in vehicle maintenance for tasks like drilling sheet metal fasteners, replacing bolt holes, installing brackets, and creating wire harness mounts (not be used on hardened steels, high-alloy steels, thick stainless steel, or other ultra-hard materials.)
- ★ 4241 High-Speed Steel (HSS) --- The 4241 high-speed steel (HSS) delivers optimal hardness and wear resistance. Featuring a nitriding black finish and 118° point angle design, it provides significant advantages in machining performance and tool life.
- ★ Useful Tips --- Ensure the drill bit is perpendicular to the workpiece surface—tilting can cause breakage or hole deviation. For beginners: Always verify proper speed and feed rates before formal workpiece machining. For larger holes, a small guide hole should be drilled first to ensure precision.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
