Walter SST Core Cut Annular Cutter 1-5/16 Inch x 2 Inch Depth

Drill Smarter, Not Harder

When you are out on the job site with a mag drill, time is money, and a dull or binding bit is a welder's worst nightmare. The Walter SST Core Cut annular cutter (1-5/16" x 2") is built to keep you working efficiently through the toughest steel. Whether you are fabricating beams for a new structure or modifying heavy machinery, this cutter delivers clean, precise holes in a fraction of the time it takes with traditional twist drills. The secret is in the SST surface treatment—a special bronze coating that acts like a permanent lubricant shield. It sheds heat and prevents metal from sticking to the bit, which is a game-changer when you are drilling through gummy materials like aluminum or tough stainless steel.

Forget about fighting your drill or constantly stopping to clear chips. The Walter SST cutter features extra-large flutes that eject metal shavings instantly, keeping the cutting path clear and your drill running smooth. The 2-inch depth of cut allows you to tackle thick plate and stacked materials in a single pass. Plus, the universal shank means you can grab this bit and lock it into almost any standard magnetic drill without hunting for an adapter. The result is a hole so smooth and burr-free that you can often slide a bolt right in without wasting time grabbing a grinder to clean up the edges.

Durability is key in the field, and this cutter is designed to last. The friction-reducing technology means the cutting edges stay cooler and sharper for longer, saving you trips to the tool crib for replacements. From structural steel to delicate stainless fabrication, the Walter SST Core Cut gives you the confidence to drill accurate holes quickly, ensuring your fit-up is perfect every time. Upgrade your drilling game with a tool that works as hard as you do.
