Walter SST Annular Cutter 1-inch x 2-inch Universal Shank

Drill Faster, Last Longer on the Job Site

For professional welders and fabricators, time is money, and changing out dull drill bits is a frustration you don't need. The Walter 05A400 SST Core Cutter is built to keep you working. With a 1-inch diameter and a 2-inch depth of cut, this tool is perfect for creating bolt holes in beams, plates, and heavy machinery. The "SST" stands for Super Speed Tip, but for you, it means a cutter that glides through metal without overheating. The special bronze coating isn't just for looks; it acts as a lubricant shield, stopping the cutter from binding up even when you are pushing hard through thick structural steel or stainless plate.

One of the biggest headaches with magnetic drills is clearing chips. If the chips clog, the bit breaks. Walter has solved this with extra-large, fully ground flutes that channel debris out of the hole instantly. This means you can drill cleaner holes faster, with less downtime spent clearing the cutter or deburring the exit hole. The finish produced is smooth and precise, often eliminating the need for secondary reaming or grinding. This efficiency makes it an essential tool for structural erectors, pipefitters, and maintenance crews who demand reliability in the field.

Compatibility is never an issue with the 05A400. It comes equipped with a universal shank that fits securely into almost any standard magnetic drill or stationary press you have in the shop. Whether you are drilling vertically, horizontally, or overhead, the secure grip ensures the bit runs true, reducing wobble and improving accuracy. From aluminum fabrication to heavy-duty steel construction, this core cutter delivers the durability and speed required to meet tight project deadlines. Stop struggling with standard bits that burn out; upgrade to the Walter SST and feel the difference in every cut.
