05B406 - Walter Icecut 1-3/8 Inch x 2 Inch Depth Annular Cutter AlCrN Coated

Advanced AlCrN Technology for Precision Drilling

The Walter Icecut Annular Core Cutter (SKU: 05B406) represents a significant leap forward in hole-making technology for industrial applications. Engineered with a diameter of 1-3/8 inches and a cutting depth of 2 inches, this tool is specifically designed to address the limitations of traditional high-speed steel and standard coated cutters. The defining feature of the Icecut series is its exclusive Aluminum Chromium Nitride (AlCrN) coating. Unlike standard Titanium Nitride (TiN) or Titanium Aluminum Nitride (TiAlN) coatings, AlCrN forms a protective thermal barrier that allows the cutter to withstand extreme operating temperatures—up to 200°C higher than its predecessors. This thermal stability is critical in high-production environments where friction heat can rapidly degrade cutting edges.

From a tribological perspective, the AlCrN coating not only resists heat but also provides a slicker surface that reduces friction coefficients during the cut. This makes the Icecut particularly advantageous in scenarios where liquid coolants or lubricants are either prohibited, such as in certain clean-room fabrication tasks, or logistically difficult to apply, such as overhead drilling on structural steel. The coating preserves the hardness of the substrate material even under high thermal stress, ensuring that the cutting geometry remains intact for longer periods. This results in cleaner, burr-free holes and a substantial reduction in tool changeover downtime.

The cutter features a standard 3/4-inch Weldon shank, ensuring compatibility with a vast array of magnetic drilling units and stationary drill presses. The geometry of the cutter is optimized for efficient chip evacuation, preventing clogging that can lead to catastrophic tool failure. By removing material only at the periphery of the hole, rather than converting the entire volume to chips like a twist drill, the Icecut requires less horsepower and thrust, reducing wear on the machine motor and fatigue for the operator. This unit is an essential asset for MRO professionals requiring precision, durability, and the flexibility to operate in lubricant-restricted environments.
