Walter SST Core Cut Annular Cutter 1 Inch x 2 Inch Depth Universal Shank

Walter 1" x 2" SST Core Cut: The Welder's Choice for Mag Drilling

When you are out in the field or in the shop fabricating structural steel, you need a mag drill bit that cuts fast and lasts long. The Walter 05E400 1" x 2" SST Core Cut Annular Cutter is built exactly for that purpose. This cutter utilizes Walter's exclusive SST (Super Surface Treatment), a specialized bronze coating that acts as a shield against heat and friction. Unlike standard high-speed steel cutters, the SST Core Cut has a non-porous surface that allows chips to slide off effortlessly. This means less binding, less heat buildup, and a significantly longer tool life, even when drilling through tough stainless steel or thick structural plate.

The universal shank is a major advantage for welders using different brands of magnetic drills. Whether your rig uses a standard Weldon shank or a similar quick-connect system, this cutter is designed to lock in securely and transfer maximum torque to the cut. The 1-inch diameter and 2-inch depth capacity make it ideal for drilling bolt holes in beams, plates, and heavy machinery frames. The cutter's geometry features an aggressive yet stable tooth design that bites into the metal cleanly, reducing the chatter and vibration that can lead to premature breakage.

Chip removal is critical when drilling deep holes. Walter has engineered this cutter with fully ground, extra-large flutes that channel chips out of the hole rapidly. This prevents the cutter from clogging and overheating, ensuring that you get a clean, burr-free hole every time. No more fighting the drill or stopping to clear chips constantly. With the Walter 05E400, you get speed, precision, and the durability required for professional welding and fabrication projects.

Why Fabricators Prefer Walter SST

• Faster Drilling: Reduced friction allows for higher feed rates.
• Clean Finish: Leaves a smooth hole that often requires no deburring.
• Versatile Application: Excellent performance on mild steel, stainless, and aluminum.
