01C506 - Walter Letter "F" Sst Drill Bit

Drill Stainless Steel Without the Headache

Every welder knows the frustration of drilling through stainless steel only to have the bit burn out halfway through. The Walter SST+ Letter "F" Drill Bit (0.2570") is the solution to that struggle. Infused with a high-performance cobalt blend, this bit is built to withstand the intense heat generated when drilling hard metals. It cuts aggressively and stays sharp, allowing you to punch through stainless, mild steel, and aluminum with ease. If you are fabricating custom parts or tapping holes that require a precise Letter F clearance, this is the tool that will get the job done right the first time.

Stop wasting time with center punches. The Walter SST+ features a smart "Speed Tip" that centers itself the moment you pull the trigger. It won't skate across your polished stainless sheets or rounded pipes, ensuring your holes are exactly where you need them. This is especially useful for field work or awkward positions where you can't easily apply massive pressure. The bit does the work for you, biting in clean and fast.

The design also features a back-tapered body and a special bronze coating. These elements work together to reduce friction, meaning the drill doesn't bind up as you get deeper into the material. The unique flute shape pulls chips out and away from the cutting zone quickly, keeping the tip cool and preventing work-hardening of the metal. Upgrade your toolbox with the Walter 01C506 and experience the difference a professional-grade cobalt bit makes in your daily fabrication tasks.
