• Special Hi-Molybdenum tool steel
• Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance
• Body and clearance are gold surface treated for maximum lubricity
• Ultra Bor will substantially outperform cobalt drills in work hardening stainless steel and other tough drilling applications
• Ultra cut super premium
• Low temperature stress relief improves lubricity and toughness
• Drills are heat treated at 2185 deg F and then nitro-carburize finished at 950 deg F to be measurably harder than high speed steel
• Space age nitro-carburized steel withstands substantially higher drilling temperatures while maintaining sharpness
