05B309 - Walter ICECUT 9/16" x 2" Annular Cutter with AICrN Coating

Advanced AICrN Technology for Superior Drilling Performance

The Walter 05B309 ICECUT Annular Cutter represents a significant leap forward in core drilling technology. Designed for heavy-duty industrial applications, this 9/16-inch diameter cutter features a 2-inch depth of cut, making it versatile for a wide range of structural and fabrication tasks. The defining feature of the ICECUT series is its exclusive coating—a unique blend of chromium and aluminum (AICrN). This advanced coating technology is engineered to outperform traditional Titanium (TiN) and Titanium-Aluminum (TiAlN) coatings by a substantial margin.

Heat is the primary enemy of cutting tools, particularly when drilling through tough materials like stainless steel or structural alloys. The AICrN coating on the Walter 05B309 is capable of withstanding temperatures at least 200 degrees Celsius higher than standard TiAlN cutters. This exceptional thermal stability allows the cutter to maintain its hardness and cutting edge even under extreme stress. Furthermore, the coating acts as a thermal barrier, directing heat into the chip rather than the tool or the workpiece. This is particularly beneficial in scenarios where external lubrication is difficult to apply or must be minimized, although using a coolant is always recommended for maximum longevity.

Beyond the coating, the physical geometry of the ICECUT is optimized for efficiency. The cutter features fully ground, extra-large flutes that facilitate rapid chip evacuation, preventing clogging and heat buildup. The modern tooth design ensures a smooth cutting action with reduced vibration, resulting in cleaner holes and less wear on the magnetic drilling unit. The universal shank design ensures compatibility with a broad spectrum of magnetic drills and stationary machines, making the 05B309 a flexible addition to any tool crib. Whether you are working with aluminum, stainless steel, or heavy structural plate, this annular cutter delivers precision, speed, and durability.
