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

Precision Holes for Professional Fabricators

When you are out in the field or in the shop, time is money, and the quality of your prep work determines the quality of your weld. The Walter 05A308 SST Core Cut Annular Cutter is built to give welders and fabricators the cleanest, fastest holes possible. Measuring 1/2 inch in diameter with a 2-inch depth of cut, this cutter is perfect for prepping bolt holes in thick mounting plates, structural columns, and chassis frames. Unlike standard twist drills that chew through metal and leave rough edges, this annular cutter slices a clean ring, leaving you with a precise hole that often requires no deburring or secondary finishing.

The secret to its performance lies in the "SST"—Super Speed Tip. Walter has applied a high-tech bronze surface treatment that makes the cutter incredibly slick. This means less friction as it spins through steel or stainless steel, keeping the tool cooler and helping it last longer. Heat is the enemy of any cutting tool, and by staying cooler, the SST Core Cut maintains its cutting edge hardness for more holes per bit. The extra-large flutes are designed to throw chips out of the hole quickly, so you don't have to stop and clear the cutter halfway through a thick plate.

This bit features a universal shank, meaning it will lock securely into almost any standard magnetic drill press you have on the truck or in the shop. It is designed to cut through a variety of metals, including aluminum and stainless steel, without bogging down. Because it removes less material than a solid drill bit (converting the center into a slug rather than chips), it puts less strain on your drill motor. This efficiency allows you to punch through heavy steel faster and with less physical effort.

Upgrade your drilling setup with the Walter 05A308. Whether you are retrofitting structural steel or fabricating custom parts, this core cutter delivers the accuracy and speed you need to get the job done right the first time. Say goodbye to wandering drill bits and jagged holes, and hello to professional-grade precision.
