05B008 - Walter ICECUT 1/2-Inch x 1-Inch AICrN Coated Annular Cutter

Advanced AICrN Technology for Precision Hole Making

The Walter 05B008 ICECUT Annular Cutter represents a significant leap forward in metal core drilling technology. Designed for industrial professionals who demand precision and longevity, this 1/2-inch diameter cutter with a 1-inch depth of cut utilizes a proprietary Aluminum Chromium Nitride (AICrN) coating. Unlike traditional Titanium Nitride (TiN) or Titanium Aluminum Nitride (TiAlN) coatings, the AICrN blend is engineered to withstand extreme thermal stress. In rigorous testing, this coating has demonstrated the ability to endure operating temperatures at least 200 degrees Celsius higher than conventional alternatives. This thermal stability is crucial when drilling through tough alloys like stainless steel or when operating in environments where liquid coolants cannot be used.

The structural integrity of the ICECUT series is further enhanced by its substrate material and geometric design. The cutter features fully ground, extra-large flutes which are critical for rapid chip evacuation. In deep hole drilling, chip packing is a common cause of tool failure; Walter’s design ensures that swarf is ejected efficiently, reducing friction and heat buildup at the cutting edge. The modern tooth geometry is optimized to bite cleanly into the material, reducing the thrust load required by the magnetic drill motor and minimizing operator fatigue.

Versatility is a core component of the 05B008's engineering. It is equipped with a universal shank, ensuring compatibility with a wide array of magnetic drilling units and stationary drill presses found in MRO shops and fabrication floors. While the cutter excels in standard structural steel, its advanced coating makes it particularly effective for harder materials and aluminum, where chip welding can often be a problem. By preventing the material from adhering to the cutting edge, the AICrN coating ensures a clean, burr-free finish that often eliminates the need for secondary reaming or deburring operations.

For industrial applications involving structural steel erection, bridge work, or heavy equipment repair, the Walter ICECUT offers a reliable solution that balances speed with durability. Its resistance to high stress and impact loads makes it a preferred choice for challenging drilling conditions where tool failure leads to costly downtime.
