Walter 05-F 112 Carbide Annular Cutter 12mm x 30mm Depth

Drill Smarter, Not Harder with Walter Carbide Cutters

If you are a welder or fabricator tired of burning through drill bits on stainless steel or fighting with dull tools on cast iron, the Walter 12mm x 30mm Carbide Core Cut annular cutter is the solution you need. SKU 05F112 is built to tackle the toughest metals in your shop. Unlike standard twist drills that require massive amounts of pressure and leave messy, burred holes, this annular cutter removes material only at the periphery of the hole. This means you are converting less metal into chips, requiring less horsepower and significantly less physical effort to punch through thick plate.

The secret to this cutter's performance lies in its carbide tips. Carbide is significantly harder and more heat-resistant than High-Speed Steel (HSS). This makes the Walter Core Cut ideal for drilling stainless steel, which has a tendency to work-harden and destroy lesser bits. With this tool in your magnetic drill, you can achieve clean, precise 12mm holes in seconds, leaving a finish that often requires no secondary deburring. The 30mm depth capacity allows you to drill through standard structural tubing, pipe walls, and heavy plate with ease.

Versatility for Every Job Site

Whether you are working on a flat bench in the shop or clinging to a vertical beam on a job site, this cutter performs. It is designed to handle uneven surfaces and can even be used for drilling into curved materials like pipe, where traditional bits might walk or wander. The optimized flute design clears chips quickly, preventing the cutter from binding up mid-cut. This is essential for maintaining speed and accuracy during critical fabrication tasks.

Investing in Walter Carbide Core Cut technology means investing in your own efficiency. You spend less time changing dull bits and more time fabricating. The cutter is compatible with most standard magnetic drilling units, making it an easy upgrade for your existing setup. From mild steel to exotic alloys, this tool gives you the confidence to drill any hole, anywhere, knowing you have the cutting power to get the job done right the first time.
