05B815 - Walter ICECUT 15/16 Inch x 4 Inch Depth Annular Cutter

High-Performance Drilling with Walter ICECUT Technology

The Walter 05B815 ICECUT Annular Cutter represents a significant leap forward in magnetic drilling technology. Engineered for heavy-duty industrial applications, this 15/16-inch diameter cutter features a 4-inch depth of cut, making it suitable for penetrating thick structural steel, plates, and tubing. The defining characteristic of the ICECUT series is its proprietary AICrN (Aluminum Chromium Nitride) coating. Unlike standard Titanium (TiN) or Titanium-Aluminum (TiAlN) coatings, AICrN is formulated to withstand extreme thermal stress, maintaining hardness and cutting edge integrity at temperatures up to 200°C higher than conventional alternatives. This makes the 05B815 an exceptional choice for fabrication shops and MRO environments where tool longevity and cycle time are critical.

Beyond its thermal properties, the physical geometry of the cutter is optimized for efficiency. The bit features fully ground, extra-large flutes that facilitate rapid chip evacuation. This is crucial when drilling deep holes (up to 4 inches), as chip clogging is a common cause of cutter breakage and poor surface finish. The modern tooth design reduces the mechanical load on the magnetic drill motor while ensuring a clean, burr-free hole. This cutter is particularly effective on difficult materials such as stainless steel and aluminum, where heat generation and chip welding are frequent issues. The universal shank design ensures compatibility with a wide range of magnetic drilling units, allowing for seamless integration into your existing tool inventory.

For operations where liquid coolant is impractical—such as overhead drilling or finished surface work—the ICECUT's heat-resistant coating provides a distinct advantage, allowing for dry drilling or minimum quantity lubrication (MQL) without sacrificing tool life. Whether used in the field for structural erection or in the shop for precision fabrication, the Walter 05B815 delivers consistent, high-quality results.
