Walter SST Annular Cutter 11/16 Inch x 1 Inch Depth

Precision Fabrication with Walter 05A011 Annular Cutters

For welders and fabricators, hole making is a critical step that can dictate the pace of an entire project. The Walter 05A011 SST Core Cutter is a 11/16" x 1" annular cutter built to streamline this process. Unlike traditional twist drills that must convert the entire volume of the hole into chips, this core cutter efficiently cuts a ring of material, leaving a solid slug. This mechanical advantage translates to faster feed rates and cleaner holes with minimal effort. The cutter is crafted from premium high-speed steel and treated with Walter's exclusive SST bronze surface treatment. This treatment is not merely cosmetic; it provides a slick, heat-resistant barrier that prevents chips from welding to the tool, a common issue when drilling aluminum or gummy stainless steels.
