Features
- Special Hi-Molybdenum tool steel.
- 135° split point for fast penetration and accurate starting without a center punch.
- Precision ground point, body, clearance and drill diameter for the ultimate in accuracy and performance.
- Body and clearance are gold surface treated for maximum lubricity.
- Drills are heat treated at 2185° F and then nitro-carburize finished at 950° F to be measurably harder than high speed steel.
- Space aged nitro-carburized steel withstands substantially higher drilling temperatures while maintaining sharpness.
- Recommended for use in work hardening grades of stainless steel and other hard metal drilling applications.
