The OSG Carbide Drill 3XD with WD1 coating and through-coolant capability is a precision solid carbide drill built for professional machining. With a 5/16 inch diameter and a 3XD length-to-diameter ratio, it delivers rigid, accurate holes across a range of materials, from tough alloys to softer workpieces. The WD1 coating boosts wear resistance, while the through-coolant design with an oil hole ensures efficient cooling and chip evacuation for longer tool life.
- 3XD geometry for rigidity and precision: The 3XD length-to-diameter ratio provides stable drilling, minimizes deflection, and helps maintain hole concentricity even in demanding materials.
- WD1 coating for wear resistance: The WD1 coating enhances surface durability, reducing wear and extending tool life in high-temperature drilling environments.
- Through-coolant with oil hole for efficiency: Direct coolant delivery and lubrication to the cutting edge improve heat management, improve chip evacuation, and boost productivity.
Together, these features translate into a drilling solution that delivers consistent hole quality, minimizes downtime, and extends tooling life. The OSG Carbide Drill 3XD with WD1 coating and through-coolant design helps you tackle tough alloys and softer materials with confidence, streamlining setups, reducing tool changes, and improving overall productivity in machining, automotive, aerospace, and general manufacturing environments.
