  • HRC55 tungsten carbide resists wear
  • R0.5 tapered ball nose profiles complex 3D contours
  • 5 mm flute length reaches deep features
  • 50 mm overall length fits standard CNC holders

HRC55 Tapered Ball Nose End Mill R0.5x20.5xD4x50L

This solid carbide cutter carries an HRC55 hardness rating and a protective coating for CNC milling. The tapered ball nose geometry suits 3D contouring and finishing passes. It is sold as a single piece for industrial cutting and engraving work. Safety notes restrict use to persons aged 18 and over.

Suited for detailed 3D milling and engraving

Buyers needing a flat-end profile or a different radius should choose another tool. The 50 mm overall length limits reach in very deep cavities. The fixed 4 mm shank diameter requires a compatible collet or holder. High-volume production lines may prefer multi-flute or indexable alternatives.

Questions about this item

How long does the 50 mm overall length hold up under sustained CNC milling before deflection becomes the limiting factor?

The 50 mm overall length keeps the cutter rigid, so deflection only becomes noticeable after extended deep-pocket passes in harder alloys.

Does the tungsten solid carbide body with HRC55 coating stay cool and quiet during all-day production runs?

The coated carbide dissipates heat efficiently and runs quietly, so spindle load and noise remain stable throughout continuous shifts.
