01J007 - Walter # 7 Sst Stub Drill

Heavy-Duty Drilling for Fabricators: Walter #7 Cobalt Stub Bit

For welders and fabricators, a broken drill bit can mean a ruined workpiece or wasted time extracting fragments. The Walter #7 SST Stub Drill is built to solve this problem. Known for its rugged construction, this stub-length bit is significantly shorter than standard jobber bits, making it far more resistant to snapping and bending. This extra rigidity is perfect for drilling out spot welds, creating rivet holes in sheet metal, or working in tight spaces where a long bit is unwieldy. The core is made from a high-grade cobalt blend, giving it the heat resistance needed to cut through work-hardened stainless steel without burning up.

The performance of the Walter 01J007 is enhanced by its advanced geometry and coating. The 135-degree (typical for SST) split point allows for aggressive penetration with less feed pressure, reducing operator fatigue during repetitive drilling tasks. You can place the tip exactly where you need it, and it will cut instantly without wandering. The exclusive bronze SST surface treatment helps chips slide out of the flutes easily and keeps the cutting edge cool, ensuring that the bit stays sharp hole after hole.

Whether you are working on an automotive body panel, installing HVAC ducting, or fabricating a stainless steel enclosure, the Walter #7 SST Stub Drill provides the reliability you need. It turns the frustrating task of drilling hard metals into a smooth, predictable process. Equip your shop with drill bits that work as hard as you do.
