01H124 - Walter 3/8 Sst Stub Qck Shank

Heavy-Duty Stub Drill for Tough Metal Fabrication

When you are welding and fabricating, you often encounter situations where a standard drill bit just won't cut it—literally or figuratively. The Walter 01H124 3/8" SST Stub Drill Bit is built to handle the abuse of heavy industrial environments. Known as a "stub" or screw machine length bit, its short profile provides maximum stiffness. This is critical when you are leaning into a hand drill to push through a piece of stainless steel frame or sheet metal; where a longer bit might flex and snap, this Walter bit stays rigid and drives through.

No More Wandering or Center Punching

Time is money in the shop. The 135-degree split point on this bit is a game-changer for efficiency. It centers itself the moment it touches the metal, preventing the bit from skating across the surface and damaging the finish. This allows you to drill accurate holes precisely where you need them, often without needing to grab a hammer and center punch first. It cuts freely and produces small chips that clear easily, leaving a clean hole that requires minimal deburring.

Secure Grip with Quick Shank

Nothing is more frustrating than a drill bit spinning inside the chuck when you are halfway through a hole. The Walter 01H124 features a Quick Shank design, which includes specially machined flats on the shank. These flats give your drill chuck jaws a solid surface to grab onto, ensuring zero slippage even under high-torque conditions. This is especially important when drilling hard materials like stainless steel, where maintaining constant cutting pressure is vital to prevent work-hardening the metal.

Built for the Welder's Needs

This bit is specifically formulated to withstand high temperatures and abrasive materials. The bronze surface treatment helps shed heat, keeping the cutting edge sharper for longer. It is the perfect accessory for your tool crib, ideal for drilling rivet holes, accessing tight spaces inside weldments, or general fabrication work on mild steel, aluminum, and stainless. When you need a hole drilled fast and you can't afford a broken bit, reach for the Walter SST Stub.
