Description
The OSG Carbide Drill 5XD, WD1 Coated, Solid, 18.5mm is a high-performance, solid carbide drill built for precision drilling across metals, composites, and other materials. Designed for engineers, machinists, and skilled tradespeople, it delivers clean, accurate holes with reliable repeatability in a wide range of applications.
With a 5XD length-to-diameter ratio, this drill excels in deeper-hole tasks and tight work envelopes, enabling efficient drilling in a single setup. The WD1 coating enhances wear resistance and heat tolerance, helping the tool stay sharp longer and resist scoring or built-up edge during demanding runs.
- WD1-coated durability: The WD1 coating improves wear resistance and heat management, extending tool life and reducing the need for frequent tool changes in tough materials.
- 5XD depth capability: The five-times-diameter length provides deeper reach for deeper holes without re-fixturing, boosting productivity and reducing cycle times.
- Solid carbide rigidity: The rigid, stable construction maintains concentricity and consistent hole quality even under challenging cutting conditions.
In daily machining, this drill translates to fewer interruptions, steadier performance, and predictable results—from initial hole quality to finish. Its combination of extended life, deep-hole capability, and reliable rigidity makes it a dependable choice for professional shops aiming to improve throughput and build confidence in precision drilling tasks.
