This tool is optimized for high-efficiency roughing across a broad range of materials, including plain carbon steel, alloy and tool steels, stainless steel, cast iron, copper and copper alloys, and high‑temperature alloys. The 35° helix and 12° rake promote smooth cutting action and effective chip evacuation, while the Alcrona Primax coating reduces built-up edge and extends tool life in continuous or demanding machining cycles. The Weldon 10 mm shank delivers secure, repeatable clamping in standard tool holders, and the DIN 844 K geometry provides predictable performance in pocketing and deep milling operations.
