Walter SST Core Cut 1-3/8" x 2" Annular Cutter with Universal Shank

Drill Faster and Cleaner with Walter 05A406 SST Core Cutters

When you are out in the field or deep in a fabrication project, time is money, and your tools need to keep up. The Walter 1-3/8" x 2" SST Corecut Annular Cutter (SKU: 05A406) is built to help welders and fabricators blast through metal with unprecedented speed and accuracy. Unlike standard twist drills that chew up material and require massive amounts of pressure, this annular cutter removes only the periphery of the hole, ejecting a solid slug. This method requires less energy and allows for much faster penetration rates, even in tough materials like stainless steel and structural beams.

What sets the Walter SST apart is its "Super Speed Tip" technology. Walter uses a specialized surface treatment that creates an incredibly slick, non-porous surface on the cutter. This isn't just for looks—it prevents chips from welding to the tool (galling) and dramatically lowers friction. Less friction means less heat, and heat is the number one killer of cutting tools. With the 05A406, you can push your magnetic drill harder and drill more holes per hour without burning out the bit. The extra-large spiral flutes act like a conveyor belt for swarf, pulling chips out of the hole instantly so you don't get bogged down, even when drilling the full 2-inch depth.

This cutter is designed to be a workhorse for any welder using a mag drill. The universal shank drops right into most standard arbors, so you don't have to hunt for special adapters. Whether you are framing a steel building, fabricating custom parts, or doing maintenance repairs on heavy machinery, the Walter SST Corecut delivers a clean, burr-free 1-3/8" hole every time. Stop fighting with dull bits and overheating drills—upgrade to the Walter SST and feel the difference in every cut.

Why Welders Choose Walter SST

• Heat Resistance: Stays cooler during operation, which is essential when drilling work-hardening materials like stainless steel.
• Maximum Efficiency: The smart tooth geometry and large flutes clear chips fast, preventing binding and breakage.
• Ready for Anything: Tough enough for structural steel, precise enough for aluminum and stainless.
