Walter 15/16 Inch Carbide Tipped Annular Cutter - 4 Inch Depth

Drill Through Stainless Like Butter

Every welder knows the frustration of burning through drill bits when working with stainless steel or cast iron. The Walter 15/16" x 4" Carbide Core Cut Annular Cutter (05D815) is the answer to those headaches. Built for the professional who needs to get the job done right the first time, this cutter combines the speed of an annular cutter with the extreme hardness of tungsten carbide. If you are working on a magnetic drill and need to punch a deep 15/16-inch hole through thick plate or pipe, this is the tool that won't let you down.

What sets this cutter apart is its ability to handle heat. Stainless steel work hardens quickly, often destroying HSS bits in seconds. The carbide tips on this Walter cutter stay sharp even at higher temperatures, allowing you to drill faster and cleaner. The 4-inch depth of cut is particularly useful for heavy structural work, allowing you to go through multiple layers or thick beams in a single pass without needing to stop and reset. The specialized flute design ejects chips efficiently, keeping the cutting path clear and reducing the risk of binding.

Beyond just raw power, this cutter offers versatility. It handles uneven surfaces and can even drill overlapping holes—something that usually causes standard twist drills to wander or break. Whether you are retrofitting steel beams, repairing heavy machinery, or fabricating custom parts, the Walter Carbide Core Cut gives you the confidence to tackle the hardest metals in the shop. Stop wasting time sharpening bits and start drilling with professional-grade efficiency.
