01J018 - Walter SST #18 Cobalt Stub Drill Bit for Stainless Steel

The Welder's Choice for Drilling Stainless Steel

Every welder knows the pain of snapping a drill bit halfway through a project, especially when working with unforgiving materials like 304 or 316 stainless steel. The Walter #18 SST Stub Drill (01J018) is the solution to this problem. Designed with a shorter, sturdier profile than standard bits, this 'stubby' drill offers the stiffness required to push through hard metals without flexing or snapping. It is the ideal tool for drilling out spot welds, creating rivet holes, or prepping fabrication assemblies.

What sets this bit apart is its composition. It isn't just standard steel; it is a heavy-duty cobalt blend capable of cutting through hardened steel and stainless alloys that would dull a regular bit in seconds. The bronze SST coating acts as a lubricant and heat shield, keeping the cutting edge cooler and sharper for longer. This is essential in welding applications where work-hardening can make a hole impossible to finish if the bit dulls halfway through.

The #18 size is a specific wire gauge size (approx. 0.1695 inches), often used for tapping or specific rivet sizes. With its quick-starting split point, you can place your hole exactly where you need it without the bit wandering off your mark. Stop wasting money on cheap bits that break and burn up. Upgrade to Walter's SST Stub drills for reliable, professional results in your fab shop.

Why Welders Prefer Stub Drills

• Less Breakage: The shorter length handles the torque and side-pressure of hand drills better than long bits.
• Better Control: Being closer to the work surface improves accuracy and reduces wobble.
• Stainless Ready: Specifically formulated to cut tough alloys commonly found in welding shops.
