Description
The OSG Carbide Drill 3XD, WD1 Coated, Solid, 18.5mm is a high-precision drilling solution built for professionals and serious DIY machinists. With a solid carbide core and a protective WD1 coating, this drill delivers reliable performance, clean holes, and longer tool life across a range of materials—from steel to aluminum and beyond.
Designed around a 3XD (three times diameter) length-to-diameter ratio, it excels in deeper holes and challenging pockets without sacrificing accuracy. The WD1 coating enhances wear resistance and helps with efficient chip evacuation, supporting consistent hole quality and cooler operation during demanding cutting cycles.
- WD1 Coating for Extended Tool Life: The WD1 layer reduces wear and heat buildup, helping the drill maintain sharpness and accuracy over more holes, which means fewer Tool Changes and lower rework costs.
- 3XD Geometry for Deep Drilling: The 3XD length-to-diameter design provides stiffness and reduced deflection in longer holes, delivering consistent hole diameter and surface finish in deeper workpieces.
- Solid Carbide Construction: Rigid, heat-tolerant carbide delivers dependable performance across steel, aluminum, and other metals, providing stable cutting action and minimal tool chatter even in tougher materials.
With the OSG Carbide Drill 3XD, WD1 Coated, Solid - 18.5mm, you gain a dependable drilling partner that supports faster cycle times, fewer interruptions, and predictable results. Its combination of coating protection, deep-hole capability, and robust core makes it a trustworthy choice for machining accuracy, productivity, and long-term tool reliability.
