2HRB 55 R0.5xD4x25x50-2f Rib

Description

2HRB 55 R0.5xD4x25x50-2F Rib is a precision 2-flute rib long-neck ball nose end mill developed for machining deep ribs, narrow grooves, 3D contours, curved profiles, and complex cavity features. Designed for hardened material applications up to 55 HRC, this cutter provides extended cutting reach where standard end mills may have limited accessibility.

The tool features a 0.5 mm corner radius, 4 mm cutting diameter, 25 mm cutting length, and 50 mm overall length. Its rib long-neck configuration provides increased reach into deep and restricted machining areas while helping maintain accurate tool positioning during profile machining. The 2-flute cutting geometry supports efficient chip evacuation and stable cutting performance when appropriate CNC machining parameters are used.

This ball nose end mill is particularly suitable for die and mould machining, precision tool making, rib machining, deep cavity work, 3D profiling, curved surfaces, and complex component manufacturing. The compact 4 mm cutting diameter combined with the 25 mm extended cutting length makes it useful for detailed machining where accessibility and dimensional control are important.

The 2HRB 55 R0.5xD4x25x50-2F Rib can be used on CNC machining centres, VMC machines, and other precision milling equipment. It is suitable for applications requiring accurate finishing of hardened steel components and intricate mould or die geometries. For best results, cutting speed, feed rate, radial engagement, axial depth of cut, and tool holding should be selected according to the workpiece material and actual machining conditions.
