Walter 1-1/8" x 1" SST Core Cut: The Welder's Choice for Precision Holes

For professional welders and fabricators, time is money, and the quality of fit-up determines the success of the job. The Walter 05A102 SST Core Cut Annular Cutter (1-1/8" diameter x 1" depth) is engineered to deliver precise, clean holes in a fraction of the time required by traditional twist drills. When preparing structural steel or stainless plate for bolting or piping pass-throughs, you need a tool that bites hard and stays cool. The secret lies in Walter's exclusive bronze SST surface treatment. This high-tech coating creates an incredibly slick surface that sheds heat and prevents the cutter from binding, even when drilling through gummy materials like aluminum or tough alloys like stainless steel.

One of the biggest frustrations with magnetic drilling is dealing with clogged flutes and jagged exit holes. Walter has addressed this with a sophisticated cutter geometry that includes fully ground, extra-large flutes. These channels act as a highway for chips, ejecting them instantly to keep the cutting zone clear. This means you can apply consistent feed pressure without worrying about the tool jamming. The result is a perfectly round hole with a superior surface finish, often eliminating the need for time-consuming deburring or reaming. You get a bolt-ready hole in a single pass.

The 05A102 is designed with a universal shank, ensuring it fits securely into the arbor of almost any standard magnetic drill press you have in your truck or shop. This versatility means you don't need to hunt for adapters or specific tool holders. Whether you are drilling horizontally on a beam or vertically on a bench, the stability and cutting aggression of the SST Core Cut remain unmatched. It is a rugged, reliable consumable that stands up to the rigors of daily fabrication work, helping you finish your projects faster and with greater precision.
