Walter SST Annular Cutter 13/16 Inch Diameter x 3 Inch Depth

Cut Faster and Cleaner with Walter SST Core Cutters

For welders and fabricators, hole preparation is often a bottleneck in the production process. The Walter 13/16" x 3" SST Core Cutter (05A613) is built to solve this problem by delivering lightning-fast drilling speeds and superior hole quality. If you are using a magnetic drill, this annular cutter is the upgrade you need. The secret lies in the SST (Super Speed Tip) technology, a specialized surface treatment that makes the cutter incredibly slick. This allows the bit to glide through metal with minimal resistance, reducing the heat that typically dulls cutting edges. You get more holes per bit and less downtime changing out worn tooling.

This cutter is a beast when it comes to deep hole drilling. With a 3-inch depth of cut, it handles thick plate and heavy-wall pipe with ease. It is also perfect for "stack drilling," where you drill through multiple layers of metal in a single pass. The 13/16" diameter is precise, and because annular cutters only cut the outer ring of the hole, you get a finish that rivals reaming. There is often no need for secondary deburring or grinding, meaning you can move straight to welding or bolting. The extra-large flutes ensure that metal chips clear out of the hole instantly, preventing the bit from clogging or overheating deep in the cut.

Designed to work as hard as you do, the Walter 05A613 fits most standard mag drills thanks to its universal shank. It is tough enough for structural steel and refined enough for stainless steel and aluminum applications. Stop fighting with dull twist drills that wander and bind. Switch to the Walter SST Core Cutter for a smoother, quieter, and more efficient drilling experience that helps you get the job done right the first time.
