Tungsten Carbide Drill Bits

High-hardness micro-drill bits and specialized carbide tooling manufactured for high-speed industrial drilling and tight-tolerance micro-machining.

Material Performance

Engineered Drilling Capability

Every tungsten carbide drill bit is fabricated to exacting dimensional tolerances, ensuring smooth chip removal and extended tool life.

Ultra-Fine Grain Carbide

Specialized Coatings

Micro-Drill Precision

Formulated from sub-micron tungsten carbide particles to achieve superior edge sharpness and resistance to micro-chipping during high-RPM operations.

Available with TiAlN, DLC, and nano-diamond coatings designed to withstand high operational temperatures and reduce friction coefficient.

Shank runout controlled within tight micrometer limits to prevent drill deflection and guarantee accurate hole placement across micro-substrates.
