Nitro 25/32" S&D Drill Bit, 1/2" Shank, 118° Split Point, M-7N HSS

Heavy-Duty Solution for Drilling Stainless Steel

For welders and fabricators, drilling through hardened materials like stainless steel or truck frames can be a nightmare without the right tooling. The Nitro 25/32" S&D Drill Bit (SKU: 1000N150) is engineered specifically to solve the problems of work-hardening and burnt bits. Unlike standard carbon steel or basic HSS bits that dull instantly on hard metals, this bit is crafted from M-7N molybdenum high-speed steel. This premium alloy is heat-treated to withstand the intense heat generated when drilling tough structural metals, ensuring the cutting edge stays sharp hole after hole.

Accuracy is paramount when you are fabricating custom parts or repairing heavy equipment. That is why this Nitro bit features a 118-degree split point. This aggressive tip geometry bites into the metal the moment it makes contact, preventing the bit from skating across the surface and ruining your finish or alignment. It also requires significantly less pressure to push through the material, which reduces operator fatigue when you are drilling out of position or using a magnetic drill press. The specialized "Black & Gold" finish acts as a built-in lubricant, reducing friction and keeping the bit cooler during operation, which is critical for preventing work-hardening in stainless steel.

This drill bit is a Silver & Deming style, meaning it combines a large 25/32-inch cutting head with a standard 1/2-inch reduced shank. This practical design allows you to drill large-diameter holes using your existing 1/2-inch hand drills or shop drill presses, eliminating the need for expensive Morse taper setups. Whether you are tapping holes for mounting bolts, repairing agricultural machinery, or fabricating structural steel components, the Nitro 1000N150 provides the reliability and cutting power you need to keep your projects moving. Made in the USA, it is a tool built for the professional tradesman.
