The tool’s 9.0 mm diameter and 19 mm length of cut provide controlled, efficient material removal with reduced deflection in confined spaces. Its 3-flute design strikes a balance between aggressive roughing and effective chip evacuation, helping maintain steady feeds and surface quality. The asymmetrical fine-pitch geometry (HRA) minimizes built-up edges and promotes smooth cutting action across a range of materials. A 35° helix enhances chip flow in deeper cuts, while the 12° rake angle supports edge stability during shoulder milling and ramping operations. The Weldon 10 mm shank with a flat ensures secure clamping in standard tool holders, enabling consistent performance in high-production setups. This end mill is well-suited for shops machining alloy and tool steels, stainless steels, cast iron, and copper-based alloys, including challenging high-temperature materials, where dependable roughing performance matters most.
