05F309 - Walter ICECUT 9/16" x 2" AICrN Coated Annular Cutter

Advanced AICrN Coating Technology for Superior Drilling

The Walter 05F309 ICECUT Annular Cutter represents a significant leap forward in hole-making technology for industrial applications. At the core of its performance is the advanced 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. It remains stable at temperatures at least 200 degrees Celsius higher than its predecessors. This thermal stability is crucial when drilling hard materials like stainless steel or when external lubrication is inconsistent or impossible to apply. The coating acts as a thermal barrier, directing heat away from the tool substrate and into the chip, thereby preserving the cutting edge's hardness and extending the tool's operational life.

Beyond the coating, the physical geometry of the ICECUT is designed for efficiency. The cutter features fully ground, extra-large flutes that facilitate rapid chip evacuation. In deep hole drilling—such as the 2-inch depth provided by this 9/16-inch cutter—effective chip removal is essential to prevent binding and heat buildup. The modern tooth design reduces cutting forces, allowing for smoother penetration and less wear on the magnetic drilling unit's motor. This combination of tribological advancement and geometric optimization makes the ICECUT a versatile solution for MRO professionals dealing with a variety of ferrous and non-ferrous metals.

The inclusion of a universal shank further enhances the utility of this tool, ensuring it can be deployed across a wide array of magnetic drilling machines without the need for specialized adapters. Whether utilized in a controlled workshop environment or a rugged field site, the Walter 05F309 delivers consistent, precision holes with improved cycle times and reduced tooling costs over the life of the project.
