Walter SST+ 13/16 Inch Annular Cutter for Stainless Steel

Stop Burning Bits on Stainless Steel

If you have ever tried to drill a clean hole through stainless steel plate with a standard bit, you know the frustration: smoke, heat, and a dulled edge before you even break through. The Walter 05E013 SST+ Corecut is the solution for welders and fabricators who need reliable performance on the toughest jobs. This 13/16-inch annular cutter is built specifically to eat through stainless steel without work-hardening the material or overheating your mag drill.

The secret lies in the SST+ formulation. Walter has designed these cutters to stay sharp even under the high stress of drilling structural stainless and heavy steel. Because it is an annular cutter (or "slugger bit"), you aren't grinding the entire hole into dust—you are just cutting a precise ring. This means you can punch a 13/16" hole through 1-inch thick plate in a fraction of the time it would take with a twist drill, and you get a burr-free finish that is ready for bolting or welding immediately. No more deburring, no more stepping up drill sizes.

Compatibility is never an issue with the 05E013. It features a Universal Shank that fits almost any magnetic drill you might have in the shop or on the truck, whether it's a Hougen, a Nitto, or a standard Weldon chuck. It locks in tight and runs true. Whether you are fabricating food-grade tanks, structural supports, or custom brackets, this cutter gives you the speed and accuracy you need to keep the project moving. Don't waste time swapping out burnt bits; equip your rig with a Walter SST+ and get the job done right the first time.

Field-Ready Reliability

When you are out in the field, time is money. The Walter 05E013 is designed to be robust. It resists breakage better than brittle carbide-tipped cutters, making it a safer choice for mobile fabrication where setups might not always be perfectly rigid. Remember to use a good cutting paste or coolant to keep things running smooth, and this cutter will outlast generic alternatives significantly. It’s a must-have in any serious fabricator's toolbox.
