Walter SST Core Cut Annular Cutter 11/16-Inch x 2-Inch Universal Shank

Precision Holes for Professional Fabrication

Welders and fabricators know that preparation is everything. The Walter 11/16" x 2" SST Corecut Annular Cutter (05E311) is built to streamline your hole-making process, giving you clean, precise holes ready for bolting or welding. Unlike traditional twist drills that require massive force and pre-drilling, this annular cutter removes material only at the periphery of the hole, leaving a solid slug. This method requires less energy and time, making it perfect for use with magnetic drills on heavy structural beams or plates. The 2-inch depth capacity allows you to drill through thick stock or stacked plates with ease.

What sets this cutter apart is Walter's proprietary SST (Super Speed Tip) surface treatment. This bronze-colored coating isn't just for looks; it provides a slick, low-friction surface that resists heat buildup. When drilling tough materials like stainless steel, heat is the enemy. The SST coating keeps the cutting edge cooler, preserving the temper of the steel and extending the life of the cutter. Combined with a sophisticated tooth geometry, this tool slices through metal smoothly, leaving a hole finish that is virtually burr-free. This means you spend less time grinding and cleaning up holes and more time assembling and welding.

The 05E311 is designed with a Universal Shank, making it compatible with almost any magnetic drill rig you might have in your shop or truck, including major brands like Hougen, Nitto, and Jancy. The extra-large spiral flutes effectively channel chips out of the hole, preventing clogging even during deep 2-inch cuts. Whether you are erecting steel structures, repairing heavy machinery, or fabricating custom parts, the Walter SST Corecut offers the reliability and speed professional welders demand.
