Nitro 21/32" S&D Black & Gold Drill Bit, 1/2" Shank, 118° Split Point

Heavy-Duty Drilling for Stainless Steel

When your fabrication project calls for drilling large holes in stubborn materials, the Nitro 21/32" S&D Drill Bit is the reliable solution you need in your toolbox. Designed specifically for the challenges of drilling stainless steel and other hard metals, this bit is constructed from M-7N molybdenum high-speed steel. This premium material choice ensures that the bit maintains its temper and cutting edge far longer than standard black oxide bits, saving you time and money on replacements. Whether you are working on structural steel, automotive frames, or custom fabrication, the Nitro 1000N series delivers consistent, clean results.

One of the most frustrating aspects of drilling metal is the bit wandering before it bites. The Nitro 21/32" bit solves this with a precision 118-degree split point. This design allows the bit to start cutting immediately upon contact, preventing damage to your workpiece and ensuring the hole is exactly where you marked it. The split point also reduces the physical force needed to push the drill, reducing operator fatigue during repetitive drilling tasks. The black and gold finish is a hallmark of quality, indicating a surface treatment that adds lubricity to keep the bit running cooler and smoother.

Versatility is a major benefit of the Silver & Deming design. By turning down the shank to a standard 1/2-inch diameter, Nitro allows you to drill 21/32-inch holes using your existing 1/2-inch drill machinery. You don't need a specialized heavy-duty press with a Morse taper to use this bit. The 3-inch flute length provides ample depth for most plate and structural drilling applications. With its Nitride surface treatment adding an extra layer of hardness, this USA-made drill bit is built to perform in the toughest shop environments, cutting through stainless steel where other bits would simply burn up.
