Walter 21mm Carbide Annular Cutter 55mm Depth

Heavy-Duty 21mm Drilling Solution for Professional Welders

For welders and fabricators who demand reliability and speed on the job site, the Walter 21mm x 55mm Carbide Core Cut Annular Cutter (SKU: 05F221) is the ultimate upgrade for your magnetic drill. When working with tough materials like stainless steel or cast iron, standard drill bits often overheat, dull quickly, or fail to penetrate efficiently. This Walter cutter solves those problems by employing extra-hard carbide inserts that slice through the toughest metals with ease, allowing you to complete fabrication projects faster and with fewer tool changes.

The 55mm depth of cut is particularly useful for structural steel erection and heavy equipment repair, where drilling through thick flanges or multiple layers of material is common. Unlike twist drills that require massive amounts of pressure and leave rough edges, this annular cutter removes material only at the periphery of the hole, ejecting a solid slug. This method requires less power and force, making your magnetic drill run smoother and extending its motor life. The result is a clean, burr-free 21mm hole that is ready for bolting or welding immediately, saving you valuable time on cleanup and deburring.

Designed to perform in the harsh conditions of a welding shop or field site, the Walter 05F221 is built to resist the shock and vibration of portable drilling. Its specialized body design reduces friction, while the carbide teeth maintain their edge even when drilling dry or with minimal lubrication (though coolant is always recommended for maximum life). Whether you are retrofitting steel beams, repairing heavy machinery, or fabricating custom stainless vessels, this cutter provides the aggressive performance needed to keep your project on schedule.
