Walter SST Core Cut Annular Cutter 11/16 in x 3 in Depth

Reliable Hole Cutting for Structural Fabrication

For professional welders and fabricators, the ability to drill clean, accurate holes quickly is essential for maintaining workflow. The Walter 05A611 SST Corecut is an 11/16-inch annular cutter built to deliver speed and reliability on the job site. With a 3-inch depth of cut, it is perfectly suited for drilling through thick structural beams, heavy plates, and pipe. The key to its performance lies in the SST (Super Speed Tip) coating. This advanced treatment creates a slick, non-stick surface that glides through metal, significantly reducing the load on your magnetic drill and allowing for faster penetration rates.

Heat is the enemy of any cutting tool, especially when working with hard materials like stainless steel. The Walter SST Corecut combats this with its specialized coating and large, fully ground flutes. These flutes eject hot chips quickly, keeping the cutting edge cool and preventing the bit from annealing or dulling prematurely. This means you can drill more holes per bit, saving money on consumables and reducing downtime for tool changes. The cutter produces a clean, smooth hole that is ready for bolting or welding immediately, saving you the extra step of grinding away burrs.

Designed with the practical needs of the welder in mind, this cutter features a universal shank that fits securely into most standard magnetic drills. Whether you are erecting steel frameworks, repairing heavy machinery, or fabricating custom parts, the Walter 05A611 provides the consistent performance you need. It turns the challenging task of deep hole drilling into a smooth, efficient process, ensuring your fit-ups are precise and your projects stay on schedule.
