Walter SST Core Cut Annular Cutter 3/4 x 2 Inch Universal Shank

Cut Faster, Last Longer

When you are out in the field or busy in the shop, you need a mag drill bit that just works. The Walter 05E312 SST Core Cut is that bit. With a 3/4-inch diameter and a 2-inch depth of cut, it handles the thick plate and structural beams you deal with every day. What makes this cutter stand out is the special bronze SST coating. It looks different because it is different—this "Super Speed Tip" treatment makes the bit slippery to the metal, cutting down on friction. Less friction means less heat, and less heat means your bit stays sharp way longer than standard high-speed steel cutters.

We all know the frustration of a bit binding up or getting stuck halfway through a hole. Walter designed these cutters with huge, fully ground flutes that eject chips fast. This keeps the hole clear and lets you drill smoothly without having to fight the machine. The tooth design bites into steel, stainless, and aluminum aggressively but leaves a finish so smooth you probably won't even need to touch it with a grinder or file. It’s a huge time saver when you have dozens of bolt holes to prep.

Compatibility is key, and the universal shank on this cutter is a lifesaver. It fits almost any magnetic drill you have lying around, whether it uses a standard Weldon flat mount or other quick-connect systems. You don't need to worry about grabbing the wrong bit for the wrong drill. Just lock it in and start drilling.

Whether you are drilling through I-beams, truck frames, or thick stainless plate, the Walter SST Core Cut takes the abuse. It is built tough to handle the vibration and stress of heavy fabrication work. Stop burning through cheap bits and constantly sharpening; switch to a cutter that is designed to keep up with the pace of professional welding and fabrication.
