Walter SST Core Cut Annular Cutter 1-9/16 Inch x 1 Inch Depth

Precision Hole Cutting for Professional Fabricators

When your project demands precise, large-diameter holes in structural steel or stainless plate, the Walter 05A109 SST Corecut Annular Cutter delivers the performance professional welders and fabricators rely on. Traditional twist drills require massive amounts of power and physical effort to drill holes over an inch in diameter. The SST Corecut annular cutter changes the game by cutting only the periphery of the hole, removing a solid slug of material. This method is faster, requires less energy, and produces a far superior hole finish compared to conventional drilling methods. With a diameter of 1-9/16 inches and a cutting depth of 1 inch, this tool is perfectly sized for bolt holes, pipe pass-throughs, and heavy fabrication tasks.

What sets the Walter SST apart is its specialized bronze surface treatment. This advanced coating acts as a shield against heat and wear. When drilling through abrasive or work-hardening materials like stainless steel, heat buildup can destroy a standard bit in minutes. The SST coating lubricates the cut and dissipates heat, allowing you to drill more holes per bit. Combined with an exclusive tooth geometry that balances the cutting load, this cutter stays sharp longer, reducing downtime for tool changes and lowering your cost per hole.

Designed for the real-world conditions of welding shops and construction sites, the 05A109 features a universal shank that fits most magnetic drills. This "one-shank-fits-all" approach simplifies your toolbox management. The cutter is also robust enough to handle the vibration and stress of on-site machining. Whether you are erecting steel beams, repairing heavy machinery, or fabricating custom parts, the Walter SST Corecut ensures that every hole is round, accurate, and clean. Stop fighting with dull bits and rough edges; upgrade to the efficiency of Walter's advanced core cutting technology.
