Walter 1-Inch Carbide Annular Cutter 2-Inch Depth Universal Shank

Punch Through Tough Metal Fast

If you've ever burned up a standard bit trying to drill a 1-inch hole in stainless steel, you know the frustration. The Walter 05H400 Carbide Core Cut Annular Cutter is built to solve exactly that problem. Unlike standard high-speed steel bits that dull the moment they get hot, this cutter uses extra-hard carbide tips that eat through the toughest metals. Whether you are working with stainless steel, cast iron, or hard alloys, this bit stays sharp and keeps cutting, saving you time and money on replacements.

Built for the Mag Drill

This cutter is designed with a Universal Shank, meaning it will fit just about any magnetic drill you have in the shop or on the truck. It slides right in and locks tight, ready to go to work. The 2-inch depth of cut is a huge advantage when you are dealing with thick I-beams, heavy plate, or stacked materials. You don't have to worry about the bit bottoming out before you break through the other side. Plus, because it's an annular cutter, it cuts a ring and ejects a slug, which takes way less power and force than trying to turn the whole hole into chips.

Clean Holes, Less Cleanup

One of the best things about the Walter Carbide Core Cut is the quality of the hole it leaves behind. The specialized design clears chips out of the way fast, preventing the bit from binding up. You get a smooth, precise 1-inch hole that usually doesn't need any deburring or filing. It’s perfect for field work where you need to bolt up and move on. Whether you are drilling on a flat table or tackling a curved pipe surface, this cutter bites in and tracks straight.

Why Choose Carbide?

For welders and fabricators, time is money. Swapping out dull bits or sharpening twist drills kills your momentum. This carbide-tipped cutter runs faster and lasts longer than HSS, letting you push your feed rate without destroying the tool. It’s the reliable choice for heavy-duty fabrication, structural steel erection, and any job where "good enough" just doesn't cut it.
