01J008 - Walter # 8 Sst Stub Drill

Toughness and Reliability: Walter #8 SST Cobalt Drill Bit

For welders and fabricators, a broken drill bit isn't just an annoyance—it's a stoppage in production and a potential safety hazard. The Walter #8 SST Stub Drill Bit (01J008) is engineered to withstand the rigorous demands of the welding shop. Built with a durable cobalt blend, this bit is specifically formulated to cut through the toughest materials found in the industry, including stainless steel, mild steel, and aluminum, without dulling prematurely. The cobalt content ensures that the cutting edges remain hard and effective, even as heat builds up during aggressive drilling operations.

The defining characteristic of this drill bit is its stub length design. In metalworking, rigidity is king. Longer bits tend to flex and snap, especially when drilling through thin sheet metal or when the drill is not held perfectly steady. The Walter SST Stub Drill minimizes this risk by shortening the flute and overall length, creating a compact, sturdy tool that resists torque and lateral forces. This makes it the ideal choice for drilling out spot welds, creating rivet holes, or working in confined spaces where a long bit would be unwieldy.

Performance is also driven by the 135° split point (typical for SST models), which prevents the bit from "walking" across the workpiece. This feature allows for instant penetration, ensuring that your holes are located precisely where you need them. Combined with the Bronze SST surface treatment, which promotes smooth chip evacuation and reduces friction, this drill bit cuts cooler and faster. The reduction in friction is vital for preventing work-hardening in stainless steel, a common issue that can ruin both the bit and the part.

Stop wasting money on cheap bits that snap on the first hole. Upgrade to the Walter 01J008 and experience the difference that professional-grade tooling makes. From its breakage-resistant core to its precision-ground tip, every aspect of this drill bit is designed to help you work smarter and faster. It is the ultimate solution for drilling sheet metal, round stock, and structural components with confidence.
