Walter SST Core Cut Annular Cutter 2-1/16 Inch x 1 Inch Depth

Reliable Hole Cutting for Professional Welders

When you are out in the field or on the shop floor, time is money, and equipment failure is not an option. The Walter 05A201 SST Core Cut Annular Cutter is built specifically for welders and ironworkers who need reliable, fast, and clean holes in heavy metal plate and structural members. Sized at 2-1/16 inches by 1 inch, this cutter utilizes high-speed steel enhanced with a unique bronze surface treatment. This "SST" treatment isn't just for looks—it provides a slick, non-stick surface that prevents the cutter from overheating, even during continuous heavy-duty use.

One of the biggest challenges in drilling large diameter holes is managing the heat and resistance generated by the cut. Standard cutters can drag and overheat, leading to premature dulling. The Walter SST Core Cut solves this with its advanced surface technology and precision-ground flutes. These large flutes clear metal shavings instantly, keeping the cutting zone cool and clear. This is particularly important when drilling stainless steel or thick structural beams, where heat hardening can make the material nearly impossible to drill if the tool dwells too long. With the 05A201, you get a consistent, aggressive cut from start to finish.

Compatibility is key for welders who may use different magnetic drills depending on the job. The universal shank design of this cutter ensures it fits securely into standard arbors without the need for adapters. This plug-and-play capability allows you to swap sizes quickly and get back to work. Whether you are framing a building, repairing heavy equipment, or fabricating custom parts, the clean, burr-free finish produced by this annular cutter ensures that your bolted connections fit perfectly every time. Invest in tooling that works as hard as you do with the Walter SST Core Cut series.
