01D533 - Walter 3.30Mm Sst Drill Bit

Drill Through Stainless Like Butter

Every welder knows the frustration of a drill bit that skates across the metal, squeals without cutting, or burns out halfway through a job. The Walter 3.30mm SST+ Drill Bit is the solution to those headaches. Designed specifically for the welder who needs reliable performance on tough metals, this bit bites instantly and cuts aggressively. If you frequently work with stainless steel, you know it tends to work-harden if your bit isn't sharp or fast enough. The SST+ formula combines a heavy-duty cobalt blend with a unique bronze finish to keep the cutting edge sharp and cool, slicing through the metal before it has a chance to harden up.

No More Walking or Center Punching

Time is money in the shop, and extra steps slow you down. Thanks to the 135° split point tip, this bit centers itself the moment it touches the steel. You can say goodbye to the drill bit "walking" across your workpiece and scratching the finish. You can often skip the center punch entirely, even when drilling into round tubing or pipe. This feature gives you the control you need for precise fit-ups and clean rivet holes.

Built to Last in the Real World

Whether you are out in the field with a cordless drill or in the shop at the drill press, the Walter SST+ stands up to abuse. The High Flow flute design pulls debris out of the hole quickly, which keeps the bit cooler and prevents it from jamming or snapping. While it excels at stainless steel, it is also a beast on mild steel and aluminum, making it the only 3.30mm bit you need in your toolbox. Stop wasting money on cheap bits that break after three holes; upgrade to Walter SST+ and feel the difference in every cut.
