05B311 - Walter ICECUT 11/16-Inch x 2-Inch Annular Cutter AICrN Coated

Advanced AICrN Technology for Superior Drilling Performance

The Walter 05B311 ICECUT Annular Cutter represents a significant leap forward in metal core drilling technology. Designed for industrial environments where precision and durability are paramount, this 11/16-inch diameter cutter features a 2-inch depth of cut, making it versatile for a wide range of structural and fabrication tasks. The defining feature of the ICECUT series is its proprietary AICrN (Aluminum Chromium Nitride) coating. Unlike traditional Titanium-based coatings, AICrN is engineered to withstand extreme thermal stress, maintaining hardness and cutting edge integrity at temperatures up to 200°C higher than conventional TiAlN cutters.

This thermal resilience is critical when drilling tough alloys like stainless steel or gummy materials like aluminum, where heat buildup often leads to premature tool failure. The coating acts as a thermal barrier, directing heat away from the cutter and into the chip, which preserves the tool's structural integrity. This makes the ICECUT particularly effective in scenarios where liquid coolants cannot be used or are impractical to apply, offering a reliable solution for dry or near-dry machining operations.

Beyond the coating, the mechanical geometry of the 05B311 is optimized for efficiency. It features fully ground, extra-large flutes that facilitate rapid chip evacuation. In deep hole drilling (up to 2 inches), effective chip removal is essential to prevent binding and breakage. The modern tooth design reduces cutting resistance, allowing for smoother penetration and cleaner holes with less burr formation. The universal shank ensures compatibility with a broad spectrum of magnetic drilling units, making this a flexible addition to any professional tool crib. Whether you are working in a fabrication shop or on a remote job site, the Walter ICECUT delivers consistent, high-performance results.
