Description
The Viking 44170 Ultra Dex Type 240-UB Jobber Drill Bit Set (29 Piece) is designed for durability and precision in demanding metalworking applications. Made from special hi-molybdenum tool steel, these bits outperform cobalt drills in work-hardening stainless steel by cutting beneath hardened chips for cleaner results. The 135° split point ensures fast penetration and accurate starts without a center punch, while the black and gold nitro-carburized finish improves lubricity and withstands higher drilling temperatures for long-lasting sharpness.
