Walter SST+ 27/64" Drill Bit, 3/8" Reduced Shank, Heavy Duty

Tough Bits for Tough Metal

As a welder, you know that drilling through stainless steel can be a nightmare if you don't have the right bit. You need a tool that bites hard, stays cool, and doesn't snap under pressure. The Walter 01R227 SST+ Drill Bit is built exactly for that purpose. It takes a 27/64" diameter cutter and puts it on a 3/8" reduced shank, meaning you can pop this heavy-duty bit right into your standard cordless drill or 3/8" air drill without hunting for an adapter or a bigger chuck.

The secret to this bit's performance is the 135-degree split point. Unlike cheap bits that wander all over the plate before they start cutting, this one centers itself instantly. This is a huge time-saver when you are drilling out broken bolts, prepping fabrication holes, or working on round tubing where slipping means scratching the workpiece. The SST+ material blend is designed specifically to handle the heat generated by drilling stainless steel, ensuring the cutting edge stays sharp longer than generic hardware store bits.

Stop burning through cheap bits and wasting time sharpening dull edges. The Walter SST+ series gives you the bite you need to get the fabrication job done quickly. Whether you are drilling pilot holes for tapping or clearing out rivets, this bit offers the reliability professional fabricators expect. It works aggressively on mild steel and aluminum too, making it a versatile addition to any welder's toolbox.
