Walter SST+ #25 Cobalt Stub Drill Bit - 135° Split Point

Precision Drilling for Fabricators: Walter #25 SST+ Cobalt Bit

For welders and fabricators, a reliable drill bit is as essential as a good torch. The Walter 01J025 #25 SST+ Stub Drill Bit is built to handle the rigors of metal fabrication, specifically when working with hard-to-drill materials like stainless steel and automotive sheet metal. Standard high-speed steel bits often dull quickly or snap when used with hand drills on tough alloys; the SST+ is the solution to these common frustrations.

The secret to the SST+ performance lies in its material and geometry. Manufactured from a heavy-duty cobalt blend, this bit retains its hardness even at high temperatures, allowing it to cut through work-hardened surfaces where other bits fail. The stub length (screw machine length) is particularly advantageous for welders working in tight spaces or using portable power tools. The shorter profile reduces leverage against the bit, making it incredibly resistant to breakage even if the drill is not held perfectly perpendicular.

Whether you are drilling out spot welds, creating rivet holes, or preparing stock for assembly, the 135° split point ensures the bit bites instantly. This prevents the bit from wandering, ensuring your holes are exactly where you marked them. The specialized bronze surface treatment aids in smooth drilling action, reducing binding and heat buildup. Upgrade your toolbox with the Walter 01J025 and experience the difference a professional-grade cutting tool makes in your fabrication workflow.

Fabrication Advantages

• Tough on Stainless: Cuts through hard alloys without rapid dulling.
• Breakage Resistant: Stubby design survives the stress of hand drilling.
• No Walking: Starts fast and accurate, preserving surface finish.
