01J015 - Walter SST #15 Cobalt Stub Drill Bit for Stainless Steel

Reliable Drilling for Fabrication and Repair

For welders and fabricators, a broken drill bit can mean costly downtime and frustration. The Walter #15 SST Stub Drill Bit is designed to solve the common problems associated with drilling in a welding shop environment. Its stub length design makes it incredibly tough, drastically reducing the snap-risk associated with standard jobber-length bits. This makes it the ideal tool for drilling out spot welds, rivets, or creating pilot holes in heavy-gauge sheet metal where lateral pressure might otherwise snap a longer bit.

When working with stainless steel—a common material in modern fabrication—heat buildup is the enemy. This Walter bit utilizes a high-grade cobalt blend that withstands the intense heat generated by drilling stainless, preventing the work-hardening that often ruins standard bits. The bronze SST coating acts as a lubricant and heat shield, keeping the cutting edge cooler and sharper for longer. This means you spend less time sharpening or replacing bits and more time fabricating.

The precision split point is a massive time-saver for fit-up work. It bites into the metal instantly, allowing for precise hole placement without the bit wandering, even on polished stainless or aluminum surfaces. Compact and powerful, the #15 SST Stub Drill fits easily into tight spaces often found in automotive repair or complex structural assemblies. Add this essential tool to your shop inventory to ensure you have the right bit for the toughest drilling jobs.
