Walter SST+ #33 Cobalt Stub Drill Bit

Unmatched Durability for Tough Metal Drilling

Welders and fabricators know that drilling out spot welds or making precise holes in stainless steel can be a frustrating task with inferior tools. The Walter 01J033 SST+ Stub Drill Bit (#33) is built specifically to handle the rigors of the welding shop. Unlike standard jobber length bits that can flex and snap under the torque of a powerful hand drill, this stub bit features a short, robust profile. This design virtually eliminates breakage, allowing you to apply the necessary feed pressure to cut through hardened materials without fear of snapping the tool mid-job.

At the core of this bit is a heavy-duty cobalt blend formulation. Stainless steel work hardens quickly, destroying standard high-speed steel bits in seconds. The cobalt alloy in the Walter SST+ series resists this heat buildup, keeping the cutting edges sharp cut after cut. This makes it an essential accessory for anyone working with stainless steel exhaust systems, food-grade tanks, or structural aluminum. The 135-degree split point is a critical feature for welders working in awkward positions; it bites into the metal instantly, ensuring you drill exactly where you intend without the bit skating across the surface.

The "SST" in the name stands for a specialized surface treatment that gives the bit its distinctive bronze color. This isn't just for looks—it significantly reduces friction and helps clear chips out of the hole efficiently. When drilling sheet metal, the short flutes and rigid body produce clean, round holes free of the triangulation often seen with longer bits. Whether you are drilling rivet holes, pilot holes for tapping, or removing spot welds, the Walter 01J033 provides the reliability and performance professional welders demand. Stop wasting money on brittle bits that break on the first hole and upgrade to the industrial strength of Walter SST+.
