Walter SST Core Cut Annular Cutter 1-3/8 Inch x 1 Inch Depth

Drill Cleaner, Faster Holes with Walter SST Core Cutters

Fabricators know that time is money, and changing out dull drill bits is a waste of both. The Walter 1-3/8" x 1" SST Core Cut Annular Cutter (05A106) is built to keep you working longer with fewer interruptions. If you are drilling through thick plate, I-beams, or stainless steel pipe, this cutter is your best friend. Unlike standard twist drills that require massive amounts of pressure and leave messy, jagged holes, this annular cutter removes only the periphery of the hole, ejecting a solid slug. This method requires less horsepower and less physical effort, resulting in a cleaner hole in a fraction of the time.

The secret to its performance is the SST (Super Surface Treatment). This bronze-colored coating isn't just for looks; it makes the cutter incredibly slick. Chips slide right up the flutes instead of sticking and welding to the bit. This means less heat buildup—the enemy of all cutting tools. Because it runs cooler, the cutting edges stay sharp longer, giving you more holes per dollar. The 1-3/8 inch diameter is a common size for heavy bolt clearance holes, and the 1-inch depth of cut handles most standard plate thicknesses found in structural welding and fabrication shops.

Compatibility is never an issue with the Walter SST line. The universal shank slides right into your magnetic drill, locking down tight for safe, wobble-free drilling. Whether you are in the shop or out on a boom lift, you need a cutter you can trust not to snap or dull halfway through a job. Walter Surface Technologies has a reputation for industrial-grade quality, and this core cutter lives up to that standard. Stop fighting with your drill and start cutting with precision.
