Walter SST Annular Cutter 13/16" x 1" Universal Shank

Drill Faster and Cleaner with Walter SST Technology

For professional welders and fabricators, time spent drilling holes is time away from welding. The Walter 13/16" x 1" SST Core Cutter (SKU: 05A013) is designed to speed up your workflow while delivering cleaner, more precise holes than traditional twist drills. If you use a magnetic drill for structural steel work, truck frame modification, or general fabrication, this annular cutter is built to handle the toughest jobs. Unlike standard bits that chew through metal and leave rough edges, the Walter SST cutter removes material in a solid slug, leaving a burr-free finish that often requires no secondary grinding or deburring.

What sets this cutter apart is its "Super Speed Tip" (SST) technology. Walter has applied a special bronze surface treatment that makes the bit incredibly slick. This means less friction as it cuts through steel, stainless steel, or aluminum. Less friction means less heat, and heat is the number one enemy of drill bits. By keeping the cutting edge cooler, the Walter SST cutter stays sharp longer, saving you money on replacements and downtime. The extra-large flutes are designed to eject chips quickly and efficiently, preventing the bit from binding up in deep holes. This is especially important when you are drilling through thick plate or structural beams where chip packing can stop a job in its tracks.

Compatibility is never an issue with the 05A013. It features a universal shank that fits securely into almost any standard magnetic drill press or stationary drilling machine. You won't need to hunt for adapters or worry about the bit slipping under load. Whether you are drilling 13/16" holes for bolting patterns in I-beams or creating pass-throughs for pipe and conduit, this cutter provides the reliability you need in the field or the shop. It is tough enough for stainless steel yet precise enough for aluminum, making it a versatile addition to any welder's toolkit.

Why Fabricators Choose Walter SST:

• Speed: Cuts significantly faster than solid drill bits.
• Finish: Leaves a smooth, reamer-quality hole.
• Life: Bronze coating extends tool life by reducing heat.
• Fit: Universal shank works with your existing mag drill.
