Viking Drill & Tool Super Premium Ultra Bor Type 240-UB Jobber Length Drill Sets

Edge of Arlington offers free shipping in the United States when you choose flat rate shipping.

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—low 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.
