10mm Hss steel bit

Product Description

HSS steel bits upgrade your workshop from dull, slow-cutting bits to a high-speed, heat-resistant cutting instrument. This 10mm bit solves slow penetration, excessive heat, wandering, and premature failure. It is fast, accurate, and built to last.

10mm Hss steel bit

Core Specifications

The 10mm diameter from high-speed steel covers over 60% of standard bolthole, dowel, conduit, and machinery mounting applications for M8-M10 fasteners. HSS maintains hardness up to 600°C for high-speed operation without losing cutting integrity. This bit eliminates step-drilling or reaming operations, saving valuable workshop time.

Cutting Geometry

The 135° split-point self-centering tip prevents wandering on curved surfaces and hard materials. It reduces required feed pressure by 30% compared to conventional chisel-point bits. Standard spiral flutes with 30° helix optimize chip evacuation, preventing clogging and heat retention. Polished flutes reduce friction, extending bit life and improving hole finish.

Material and Manufacturing

M2 HSS grade provides excellent wear resistance and toughness. Full heat treatment hardens to HRC 62-64 with tempering to relieve internal stresses. Precision-ground cutting edges ensure concentricity within 0.02mm. Steam-oxide or TiN coating reduces friction, increases surface hardness, and extends tool life.

Usability and Compatibility

A standard round shank fits all drill chucks including keyed, keyless, and SDS systems. Works with corded, cordless, drill presses, and magnetic drills. Best performance at 600-1000 RPM for steel with appropriate cutting fluid. Speeds and feed rates are typically stamped on packaging for quick reference.

Durability and Applications

QA testing includes concentricity, hardness, and real-world drilling tests. Drills through mild steel, stainless steel, cast iron, aluminum, brass, copper, plastics, wood, and composites. Cutting edges can be resharpened multiple times. Proper cutting fluid can extend bit life by up to 300%. Suitable for metal fabricators, plumbers, electricians, auto mechanics, cabinet makers, and DIY workshops. Order today and deploy immediately with zero configuration.
