Radiused-end clearance milling cutters are specialized tools designed for machining relief areas, undercuts, and clearance profiles that require a smooth, controlled radius at the cutting tip. This geometry provides stable engagement, reduced stress concentration, and improved surface transitions during clearance machining.
The Clearance Milling Cutter – Radiused End Geometry is engineered for precision relief milling and radiused clearance profiles in CNC machining applications.The Clearance Milling Cutter with Radiused End Geometry is engineered for precision machining of relief features, clearance pockets, and interference-removal areas commonly found in aerospace parts, mold components, valve bodies, and high-accuracy mechanical assemblies. The radiused end cutting profile enables smooth cutting action, minimizes tool-tip chipping, and produces controlled relief surfaces with improved durability.
Compared with square-end relief cutters, the radiused-end design distributes cutting loads more evenly, enhances tool life, and generates smoother transitions in clearance zones and undercut areas. Aoshiji® Custom Tool supports full customization of radius form, relief taper, cutting length, step geometry, and shank configuration based on customer drawings or 3D CAD models.
