05B501 - Walter ICECUT 2-1/16" x 2" AICrN Coated Annular Cutter

High-Performance Drilling with Walter ICECUT Technology

The Walter 05B501 ICECUT Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Designed to meet the rigorous demands of modern metalworking, this 2-1/16" diameter cutter features a 2" depth of cut, making it an essential tool for structural steel, heavy manufacturing, and on-site construction projects. What sets the ICECUT series apart is its sophisticated metallurgy and coating science. Unlike traditional high-speed steel or standard TiN-coated bits, the ICECUT utilizes a proprietary Aluminum Chromium Nitride (AICrN) coating. This advanced tribological layer provides exceptional hardness and, more importantly, outstanding thermal stability.

In heavy-duty drilling applications, heat is the primary enemy of tool life. The AICrN coating on this cutter allows it to withstand temperatures at least 200°C (392°F) higher than conventional Titanium Aluminum Nitride (TiAlN) cutters. This thermal resilience is critical when drilling through tough alloys like stainless steel or abrasive materials like aluminum, where friction heat can rapidly degrade a cutting edge. Furthermore, the coating's slick surface properties, combined with fully ground extra-large flutes, ensure rapid chip evacuation. This prevents chip packing and heat buildup inside the hole, resulting in a cleaner cut and significantly reduced mechanical stress on both the cutter and the drilling machine.

The Walter 05B501 is specifically engineered for environments where the use of liquid coolants and lubricants may be restricted, such as in overhead drilling or sensitive fabrication areas. While it performs exceptionally well with lubricants, its ability to maintain hardness at high temperatures makes it the go-to choice for "dry" or near-dry machining operations. The universal shank design further enhances its utility, allowing seamless integration with a wide array of magnetic drilling units and stationary drill presses found in professional machine shops. By choosing the ICECUT, operators invest in reduced downtime, fewer tool changes, and consistent, burr-free holes in the most challenging materials.
