About this item
- ★ Drill Bit Size --- Cutting edge diameter: 30mm; shank diameter: 1/2"; cutting edge length: 75.5mm / 2.97"; overall length: 150mm / 5.91", Included: 1 Piece x Drill Bit
- ★PRACTICAL PERFORMANCE --- The twist drill offers excellent toughness, combining a Nitriding Black and a 118° Angle design. It has significant advantages in processing performance and cost-effectiveness, achieving superior processing at low cost and striking a perfect balance between cost and quality.
- ★ Wide Applications --- For acrylic, plastic, wood, soft metals (Cu, Al alloys), carbon steel, cast iron & thin stainless steel, suitable for vehicle maintenance like sheet metal, bolt holes, brackets, wire harness mounts. (not to be used on hardened steels, high-alloy steels, thick stainless steel, or other ultra-hard materials.)
- ★ 4341 High-Speed Steel (HSS) --- Offers high hardness, excellent wear resistance, and good toughness. It is a versatile drill bit suitable for machining medium- to low-hardness materials.
- ★ 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.
