Walter 11/16 Inch Carbide Core Cut Annular Cutter with Universal Shank

Heavy-Duty Solution for Stainless and Cast Iron Drilling

For welders and fabricators, time is money, and nothing kills productivity faster than burning through drill bits on hardened materials. The Walter 11/16" x 1" Carbide Core Cut Annular Cutter (05H011) is the heavy-duty solution designed to power through the toughest metals that standard bits simply can't handle. If your work involves stainless steel, cast iron, or heavy structural alloys, this cutter is engineered to provide the bite and endurance you need to get the job done right the first time.

This cutter features a universal shank, making it a drop-in upgrade for almost any magnetic drill rig you have in your arsenal. The carbide tips are formulated to withstand the high heat and abrasion generated when drilling hard metals, allowing you to run your machine at faster speeds and feeds than you would with HSS tooling. This means you can punch more holes in less time, keeping your fabrication schedule on track. The 1-inch depth of cut is ideal for standard plate and structural beam work, providing a clean, finished hole that is ready for bolting or welding without the need for extensive deburring or secondary cleanup.

Real-world fabrication often happens in less-than-ideal conditions. Whether you are working on a curved pipe, an uneven casting, or overlapping plates, the Walter Carbide Core Cut remains stable and aggressive. Its advanced body design reduces friction and vibration, which is crucial when drilling on site where rigidity can be a challenge. The specialized flute geometry ejects chips rapidly, preventing the cutter from binding up in the hole—a common frustration when drilling deep into gummy materials like aluminum or stainless.

Durability is the core promise of this tool. By utilizing extra-hard carbide inserts, Walter has created a cutter that maintains its geometry long after other bits have failed. This longevity reduces your consumable costs over time and ensures that you aren't constantly stopping to sharpen or replace dull tools. For MRO professionals, ironworkers, and welders who refuse to compromise on quality, this 11/16-inch annular cutter delivers the reliability required for critical infrastructure and heavy machinery repair.
