05B811 - Walter Icecut 11/16" x 4" Annular Cutter with Universal Shank

Advanced Hole-Making Technology with Walter Icecut

The Walter 05B811 Icecut Annular Cutter (11/16" x 4") sets a new benchmark in industrial drilling performance. Designed for the most demanding metalworking environments, this cutter features a revolutionary AICrN (Aluminum Chromium Nitride) coating. Unlike traditional Titanium (TiN) or Titanium-Aluminum (TiAlN) coatings, the AICrN blend is engineered to withstand extreme thermal stress, maintaining hardness and cutting edge integrity at temperatures up to 200°C higher than competing products. This makes the Icecut series the ideal choice for operations where heat generation is a critical factor or where external lubrication may be inconsistent or difficult to apply.

Precision engineering is at the core of the Icecut's design. The cutter boasts fully ground, extra-large flutes that facilitate rapid chip evacuation, preventing clogging and heat buildup deep within the bore. This is particularly crucial for the 4-inch depth of cut provided by this model, allowing operators to drill through thick structural members or stacked plates without interruption. The modern tooth geometry is optimized to bite cleanly into hard materials like stainless steel and structural steel, reducing the mechanical load on your magnetic drilling unit and ensuring a burr-free finish that requires minimal secondary processing.

Versatility is key in modern MRO and fabrication settings. The Walter 05B811 is equipped with a universal shank, ensuring compatibility with a wide range of magnetic drilling machines and stationary equipment. Whether you are working in a fabrication shop or on a remote job site, the Icecut delivers consistent, high-speed performance. By reducing tool changeovers and increasing drilling speed, this annular cutter significantly lowers the cost per hole, providing a tangible return on investment for industrial users seeking efficiency and durability.

Key Technical Benefits

The primary advantage of the Icecut line lies in its tribological properties. The coating acts as a thermal barrier, directing heat into the chip rather than the tool or the workpiece. This results in a cutter that stays sharper for longer, even when drilling abrasive or work-hardening materials. For professionals who demand reliability and precision, the Walter Icecut is the superior solution for heavy-duty hole making.
