The OSG Carbide Drill 3XD with WD1 coating is a precision solid carbide drill designed for through-coolant drilling and oil-hole applications. With a 3XD length-to-diameter ratio and a 7.8 mm diameter, it delivers reliable, high-precision holes in a wide range of materials, from tough alloys to softer metals. This drill is ideal for production shops, job shops, and engineers who need consistent results in demanding drilling tasks.
The WD1 coating offers exceptional wear resistance, helping the cutting edge stay sharper longer and extend tool life. The through-coolant design, combined with an internal oil hole, improves chip evacuation and temperature control, enabling smoother cutting and reduced risk of thermal damage in deep or intricate holes.
- WD1 wear‑resistant coating: Delivers longer tool life and steadier performance by reducing wear and maintaining edge sharpness across challenging materials.
- 3XD geometry for deep-hole stability: The 3XD length-to-diameter ratio provides rigidity and precision, producing accurate holes with minimal deflection in demanding applications.
- Through-coolant with oil-hole design: Direct coolant delivery and integrated oil hole enhance cooling and chip evacuation for cooler cuts and reliable, repeatable results.
This drill helps you maintain consistent hole quality, reduces downtime from tool wear or overheating, and supports efficient, repeatable performance across a range of materials and machining setups.
