11/32" Nitro Heavy Duty Jobber Drill Bit, 135° Split Point, M-7N HSS

The Welder's Choice for Stainless Steel

Every welder knows the frustration of trying to drill through a piece of stainless steel with an inferior bit. The squealing, the smoke, and the inevitable work-hardening of the material can turn a simple fabrication task into a nightmare. The Nitro 11/32" Heavy Duty Drill Bit (SKU: 400N122) is designed to solve exactly this problem. Built for the shop that handles everything from mild steel repairs to custom stainless fabrication, this bit cuts where others burn out. The secret is in the M-7N molybdenum steel construction, which handles the high heat generated when drilling hard metals far better than standard bits found at big-box stores.

One of the standout features for fabrication work is the 135-degree split point. When you are working on a truck frame or a piece of agricultural equipment, you often can't get the workpiece into a drill press. You are drilling freehand, often in awkward positions. The split point on this Nitro bit bites into the metal the instant it touches, preventing the bit from "walking" or skating across the surface. This means you don't always need to hunt for a center punch and hammer before you start drilling, saving you time and hassle on the job site.

Durability is key in MRO and welding environments. The black and gold finish on these bits indicates a Nitride surface treatment that makes the outside of the bit incredibly hard. This protective layer keeps the cutting edges sharp longer, even when drilling abrasive materials. Whether you are drilling out broken bolts, prepping holes for tapping, or fabricating mounting brackets, the Nitro 400N122 delivers clean, precise holes time after time. Made in the USA, this is a tool you can rely on when the deadline is tight and the metal is hard.
