Walter SST Core Cut Annular Cutter 1-3/16" x 2" Universal Shank

Heavy-Duty Hole Cutting for Professional Welders

When you are out in the field or on the shop floor, you need a cutter that can punch through thick steel without bogging down. The Walter 05A403 SST Core Cut Annular Cutter (1-3/16" x 2") is built for exactly that purpose. Unlike traditional twist drills that have to remove all the material from the hole, this annular cutter only cuts the periphery, removing a solid slug. This method is far more efficient, requiring less power and force from your magnetic drill, and resulting in a cleaner, more precise hole in a fraction of the time.

This specific cutter is part of Walter's renowned SST line, which stands for Super Speed Tip. It features a unique bronze surface treatment that isn't just for looks—it's a high-performance coating designed to shed heat and resist friction. When you are drilling through tough materials like stainless steel or thick structural plate, heat build-up can kill a bit instantly. The SST coating keeps the cutter cooler, allowing you to push harder and drill faster without burning up the tool. This means you get more holes per dollar and spend less time swapping out worn bits.

The geometry of the 05A403 is optimized for the welder's reality. The extra-large flutes are fully ground to clear chips rapidly, preventing the dreaded "bird's nest" of metal shavings that can jam a cutter deep in a hole. The universal shank ensures that this bit will fit securely into almost any standard magnetic drill press you have in the shop, providing a solid connection that eliminates wobble and runout. Whether you are working on aluminum fabrication, erecting steel structures, or customizing heavy machinery, this cutter gives you the edge you need.

Stop struggling with dull bits and slow drilling speeds. Upgrade to the Walter SST Core Cut and experience the difference that premium metallurgy and design make. With a 2-inch depth of cut, you can handle thick plate and pipe with ease, leaving a burr-free finish that is ready for welding or bolting immediately. It is the reliable choice for welders who demand professional results.
