HSS Twist Drill Bits - Bright Finish

EXTRACUT HSS (High-Speed Steel) Twist Drill Bits with bright finish the foundational cutting tools for general-purpose drilling in steel, aluminum, copper, plastic, and wood. Manufactured from premium M2 high-speed steel with a fully ground bright finish, these drills deliver reliable performance across a wide range of materials and applications. The precision-ground 118-degree point geometry ensures accurate hole initiation and straight drilling with minimal walking.

Key Features

• M2 High-Speed Steel — Premium grade M2 (W6Mo5Cr4V2) HSS provides excellent red hardness up to 600°C, maintaining cutting edge integrity at elevated temperatures during continuous drilling operations.
• 118-Degree Point Angle — Standard split-point or conventional point geometry optimized for steel and general materials, providing self-centering action and reduced thrust force.
• Bright Surface Finish — Uncoated bright finish offers excellent chip evacuation and is ideal for general-purpose applications where coating cost savings are desired.
• Precision Ground Flutes — Parallel helical flutes with optimized pitch ensure efficient chip removal even in deep-hole drilling applications.
• Rolled Shank Design — Precision-rolled shank provides secure chuck grip and accurate concentricity for true-running holes.
• Full Range Sizes — Available from Ø1mm to Ø13mm in 0.1mm increments, covering metric and imperial size requirements.

Applications

General machining workshops, maintenance departments, DIY projects, metal fabrication, automotive repair, electronics manufacturing, and any application requiring reliable hole drilling in mild steel, stainless steel (light), aluminum alloys, brass, copper, plastics, and wood.
