We craft this tool from premium carbide, tailored for aluminum machining as a double-sided undercut chamfer mill. It handles both upper and lower, front and back internal hole chamfering, with 60°90°120° angles to meet diverse processing needs. The carbide build ensures durability against aluminum’s properties, while the optimized design delivers smooth, burr-free chamfers. Built with strict precision, it’s reliable for industrial aluminum internal hole processing requiring consistent, accurate undercutting.
