Walter SST Core Cut Annular Cutter 1-9/16" x 2" Universal Shank

Drill Faster and Cleaner with Walter SST Technology

For welders and fabricators, time is money, and struggling with dull or inefficient drill bits is a major drain on productivity. The Walter 05A409 SST Core Cut Annular Cutter (1-9/16" x 2") is built to solve the common headaches associated with drilling large diameter holes in tough metals. Whether you are working on a structural steel beam or fabricating a stainless steel tank, this cutter delivers speed and precision that standard twist drills simply cannot match. The "SST" stands for Super Speed Tip, highlighting the specialized bronze surface treatment that allows this tool to cut faster while generating less heat. Less heat means the cutting edge stays sharper for longer, giving you more holes per dollar.

One of the standout features for welders is the finish quality. The Walter SST Core Cut is designed to eliminate porosity and leave a burr-free, smooth surface. This is incredibly important when preparing holes for bolting or subsequent welding, as it removes the need for time-consuming cleanup work like grinding or filing. The cutter's geometry includes extra-large flutes which are essential for ejecting metal chips quickly. When you are drilling through 2 inches of solid steel, efficient chip removal prevents the bit from jamming and keeps the cutting action smooth and consistent. This design allows you to push your magnetic drill to its potential without worrying about bogging down.

Compatibility is never an issue with the 05A409. It features a universal shank that fits securely into most standard magnetic drill presses and stationary drilling equipment found in welding shops. This cutter is a workhorse capable of tackling everything from aluminum to heavy structural steel and stainless. If you are tired of burning through bits or fighting to get a clean hole, upgrading to the Walter SST Core Cut is a smart investment. It combines rugged durability with precision engineering to help you get the job done right the first time, every time.
