Walter SST Core Cutter - 2-5/16 in Diameter x 2 in Depth - Universal Shank Annular Cutter

Heavy-Duty Core Cutter for Professional Welders

When you are out in the field or working on a critical structural weldment, you need a drill bit that cuts fast and stays sharp. The Walter 05A505 SST Core Cutter (2-5/16" x 2") is built to handle the rigorous demands of professional welding and metalworking. Traditional twist drills require massive amounts of horsepower and physical force to push through thick steel, often leaving rough holes and exhausted operators. In contrast, 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, letting you drill large 2-5/16 inch holes in a fraction of the time.

Durability is where the Walter SST series truly shines. The "SST" stands for Surface Treatment Technology, a special bronze coating that makes the cutter incredibly slick and tough. This coating drastically reduces friction, which is the enemy of all cutting tools. By keeping the tool cooler, the cutting edges stay sharper for longer, even when drilling through tough materials like stainless steel or thick structural beams. The extra-large flutes are designed to throw chips out of the hole aggressively, so you don't have to stop and clear the cutter constantly. This means you can finish your prep work faster and get to welding sooner.

Designed with the welder's toolkit in mind, this cutter features a universal shank that fits securely into almost any magnetic drill you might have on the truck or in the shop. It eliminates the headache of searching for an adapter or a specific brand of bit. Whether you are drilling holes for bolting columns, running pipe through plates, or fabricating custom brackets, the Walter 05A505 provides the reliability you need. It cuts clean, accurate holes in steel, aluminum, and stainless, ensuring that your fit-up is perfect every time. Invest in tooling that works as hard as you do and experience the difference of premium Walter engineering.
