Walter SST+ Corecut Annular Cutter 1-1/16" x 1" Universal Shank

Precision Holes in Tough Metals

For welders and fabricators, preparing clean holes for bolting or pipe pass-throughs is a daily necessity. The Walter 05E101 SST+ Corecut Annular Cutter is engineered to deliver precision and speed, specifically when working with stainless steel plate and structural members. Drilling stainless steel can be notoriously difficult due to its tendency to work-harden; however, Walter's SST+ line combats this with a proprietary cobalt-blended high-speed steel construction. This ensures that the cutter stays sharp and cuts cool, preventing the material from hardening ahead of the cut.

This 1-1/16" x 1" cutter features a sophisticated tooth geometry that balances cutting forces and stabilizes the tool during entry and exit. The result is a hole with superior surface finish and tight tolerances, often eliminating the need for secondary reaming or deburring operations. For a welder, this means less time prepping and more time welding. The annular cutting process is also far more efficient than traditional drilling, as it converts a smaller volume of metal into chips, leaving a solid slug that is ejected upon completion.

Compatibility is key in a busy workshop. The 05E101 comes equipped with a Universal Shank, making it plug-and-play with most major brands of magnetic drills on the market today. You won't need to hunt for adapters or specific arbors. Simply lock it into your mag drill and experience the smooth, chatter-free performance that Walter Surface Technologies is known for. Whether you are retrofitting stainless tanks or fabricating heavy steel structures, this cutter provides the durability and performance required for professional results.
