EXOCARB® WD-4D Drills (5410)

High Performance Carbide Drills for Ferrous and Non-Ferrous Materials


The EXOCARB®-WD drill series is OSG's premium line of solid carbide high performance drills. New wavy point edge form creates sharp cutting action for reduced thrust forces, while our proprietary WD1 coating provides drastically higher hardness and heat resistance, enabling higher drilling speeds and incredible tool life.


OSG's WD1 Nano Coating Technology

Higher coating oxidation temp & hardness dramatically improve wear resistance

Wavy form cutting edge design

Sharper cutting action reduces thrust forces and produces smaller chips for easy hole processing

Ultra-fine Micrograin Carbide

Smaller grain size yield more wear resistance and better coating adhesion properties for long life
