Walter 30mm x 55mm Carbide Tipped Annular Cutter for Stainless and Hard Alloys

The Ultimate Cutter for the Job Site

When you are out on a job site or in the fab shop, time is money, and you don't have time to waste on drill bits that burn out halfway through a hole. The Walter 30mm x 55mm Carbide Core Cut (05F230) is built for welders and fabricators who need reliable performance when drilling through the tough stuff. If you work with stainless steel, cast iron, or hard structural steel, you know that standard HSS bits can dull almost instantly. This Walter cutter uses extra-hard carbide tips to slice through these materials with ease, keeping you working longer without stopping to swap out tooling.

Designed for use with magnetic drilling units, this annular cutter removes material only at the periphery of the hole, ejecting a solid slug at the end of the cut. This method is far more efficient than twist drilling, requiring less horsepower and physical effort to drill large 30mm holes. The 55mm length gives you the reach needed to penetrate thick structural members, pipe flanges, and heavy equipment frames. Plus, the advanced flute design clears chips out of the way fast, so you don't get bogged down binding in deep holes.

One of the standout features of this cutter is its ability to handle uneven and curved surfaces. Starting a hole on a pipe or a rough casting can be a nightmare with standard bits that walk or chatter. The Walter Carbide Core Cut bites in clean and stays true, giving you a perfect round hole every time. Whether you are retrofitting steel beams, repairing heavy machinery, or fabricating custom stainless vessels, this cutter delivers the speed and durability professional welders demand.

Built to Last

Durability is key in welding and MRO applications. The carbide inserts on this Walter cutter are extremely wear-resistant, meaning you get more holes per dollar compared to cheaper alternatives. It withstands the high temperatures generated when drilling hard metals, maintaining its cutting edge sharpness for the long haul.
