Walter SST+ Corecut 9/16-Inch x 2-Inch HSS Annular Cutter

Precision Holes in Tough Metal

Upgrade your magnetic drill's capabilities with the Walter 05A309 SST+ Corecut Annular Cutter. Designed for fabricators who need reliable performance, this 9/16-inch cutter offers a 2-inch depth of cut, making it perfect for drilling through thick plate, pipe, and structural members. The SST+ Corecut line is famous for its ability to cut through stainless steel and other tough alloys without losing its edge prematurely. By utilizing a specialized hardening treatment, Walter has created a bit that stays sharp longer, saving you money on replacements and downtime.

Annular cutters are superior to standard twist drills for large diameter holes because they cut the perimeter of the hole rather than turning the entire area into chips. This results in a much cleaner finish and a perfectly round hole every time. The 05A309 features a self-centering design that eliminates the need for pilot drilling or center punching—just line it up and cut. The 2-inch length allows for versatility, letting you drill through thicker stock or stacked materials in a single pass. The universal Weldon shank ensures it fits securely into almost any standard mag drill on the market.

When you are out in the field or in the shop, you need tools that work as hard as you do. The Walter SST+ Corecut reduces the physical effort required to drill, as it requires less feed pressure than solid bits. This not only reduces operator fatigue but also extends the life of your drill motor. For the best results, pair this cutter with a high-quality cutting lubricant to further reduce heat and friction. Whether you are building trailers, erecting steel structures, or repairing heavy machinery, the Walter 05A309 is the dependable choice for clean, fast drilling.
