14mm HSS metal drill bit

Product Description

HSS metal drill bits upgrade your workshop from dull, slow-cutting bits to a high-speed, heat-resistant cutting instrument. This 14mm bit solves slow penetration, excessive heat, wandering, and premature failure. It is fast, accurate, and built to last.

Core Specifications

The 14mm diameter from high-speed steel covers 65% of structural, mechanical, and plumbing applications. HSS maintains hardness up to 600°C for high-speed operation without losing cutting integrity. The versatile size handles bolthole preparation, pipe installations, conduit entry points, and machinery mounting holes. This bit eliminates step-drilling or reaming operations.

Cutting Geometry

The 135° split-point self-centering tip prevents wandering on curved surfaces and hard metals. 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 provides visual wear identification.

Usability and Compatibility

A standard 1/2-inch round shank fits all drill chucks including keyed, keyless, and SDS systems. Works with corded, cordless, drill presses, and magnetic drills. Best performance at 400-600 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, and some plastics. Cutting edges can be resharpened multiple times. Proper cutting fluid can extend bit life by up to 300%. Suitable for metal fabricators, structural steel erectors, plumbers, electricians, and auto mechanics. Order today and deploy immediately with zero configuration.
