Ultra Bor Super Premium - 135° split point for fast penetration and accurate starting without a center punch. 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; temperature stress relief improves lubricity and toughness.
Manufactured to NAS 907B specification from Premium Hi-Molybdenum Steel.
Drills are heat-treated at 2185°F and then nitro-carburize finished at 950°F to be measurably harder than high-speed steel. Space age 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. Sizes smaller than #52 have non-split points.
Ultra Bor will substantially outperform cobalt drills in work hardening stainless steel and other tough drilling applications.
