- & Drill Bit Size — Cutting edge diameter: 34 (2.819mm); shank diameter: 34; cutting edge length: 40mm / 1.57″; overall length: 66mm / 2.6″, Included: 5 Pieces x Drill Bit
- &PRACTICAL PERFORMANCE — The twist drill offers excellent toughness, combining a gold coating finish 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.
