Walter 2-1/2 Inch TCT Annular Cutter 1-1/2 Depth Weldon Shank

Stop Burning Bits on Stainless Steel

If you have ever spent half a day fighting to drill a single large hole in stainless steel or cast iron, you know the frustration of smoking bits and stalled jobs. The Walter 05D518 Carbide Core Cut is the answer to those heavy-duty drilling nightmares. This isn't just another drill bit; it is a 2-1/2 inch beast designed specifically to eat through the hard stuff that ruins standard HSS cutters. With its tungsten carbide tips, this cutter stays sharp longer and cuts faster, letting you punch through heavy plate and get on with the welding.

Time is money on the fabrication floor and out in the field. Using a magnetic drill with the Walter Carbide Core Cut means you can run at higher speeds and feeds with less down pressure. This reduces operator fatigue and puts less strain on your mag drill motor. The 1-1/2 inch depth of cut is perfect for most structural steel, pipe flanges, and equipment frames. Plus, the standard 3/4 inch shank drops right into your existing rig without needing special adapters. Whether you are working on a repair job for heavy machinery or fabricating custom stainless tanks, this cutter delivers clean, burr-free holes every time.

One of the biggest advantages for welders is the ability to drill dry or with minimal lubrication in scenarios where liquid coolant is messy or impractical (though coolant is always recommended for max life). The heat resistance of the carbide tips means you won't lose your cutting edge the moment the temperature spikes. It also handles "dirty" metal—like cast iron or rust-covered steel—much better than HSS. Upgrade your mag drill kit with the Walter 05D518 and stop dreading the large diameter holes.
