Walter 1-Inch Diameter x 4-Inch Depth Carbide Annular Cutter

Reliable Deep-Hole Drilling for Fabricators

When you are out in the field or in the shop, you need a cutter that won't quit halfway through a thick plate. The Walter 1" x 4" Carbide Core Cut Annular Cutter (05D900) is built for welders and fabricators who demand performance. This cutter is the go-to solution for drilling large, clean holes in tough metals using a magnetic drill. Unlike standard bits that dull quickly on stainless steel or cast iron, this carbide-tipped powerhouse cuts cleaner and lasts longer, saving you time and money on replacements.

The 4-inch depth of cut is a standout feature, allowing you to drill through heavy structural beams, thick mounting plates, or multiple layers of material in a single pass without needing to stop and reset. The advanced body design reduces friction and vibration, which means you get a burr-free finish that often requires no secondary deburring. This precision is essential for ensuring proper bolt fitment in structural connections and machinery assembly.

Walter's Carbide Core Cut technology also means you can run your mag drill at higher speeds. The cutter stays cooler thanks to its smart flute design that ejects chips rapidly. Whether you are retrofitting equipment, fabricating custom parts, or performing on-site repairs, this annular cutter provides the bite you need to get the job done right the first time. It fits standard Weldon shank arbors, making it compatible with most magnetic drills on the market.
