Walter Carbide Tipped Annular Cutter 4 Inch x 3 Inch Depth

Cut Big Holes in Hard Metal with Ease

Every welder knows the frustration of trying to drill a large hole in stainless steel or cast iron only to have the bit scream, smoke, and dull halfway through. The Walter Carbide Core Cut annular cutter is the solution to those headaches. Designed for the serious fabricator, this 4-inch diameter cutter allows you to punch through the toughest metals with your magnetic drill, leaving a clean, burr-free finish that usually requires no extra grinding or cleanup. With a 3-inch depth of cut, it handles thick plate and heavy structural beams without breaking a sweat.

The secret lies in the extra-hard carbide tips. While standard bits soften when they get hot, these carbide inserts love the heat and stay sharp longer. This means you can push harder and drill faster, getting the job done in a fraction of the time it takes with conventional tooling. The geometry of the cutter is also designed to reduce the load on your drill motor, meaning less wear and tear on your expensive equipment and less physical fatigue for you. It cuts a ring of metal and ejects a solid slug, which is far more efficient than turning the entire hole volume into chips.

Whether you are retrofitting pipes, installing heavy machinery, or fabricating custom parts, the 05D748 gives you the confidence to tackle large holes on site. It is particularly good at biting into uneven or curved surfaces where other bits might walk or chatter. The robust body design ensures stability, giving you a perfectly round hole every time. Stop wasting time sharpening dull bits or burning through multiple HSS cutters on a single job.

Upgrade your mag drill setup with the Walter Carbide Core Cut. It’s built for the jobs that other cutters can't handle, giving you professional results on stainless, cast iron, and other hard alloys. When you need a 4-inch hole through thick stock, trust the cutter that’s built to last.
