All dimensions in mm. Custom ball radii, neck lengths, and coatings available on request.
Manufacturing Standard
Ball-End Precision You Can Measure
Walter CNC 5-Axis Grinding
Ball radius held to ±0.003mm. Symmetric flute profile ensures equal chip load on all cutting edges throughout 3D tool paths.
Oerlikon Balzers PVD Coating
Uniform TiSiN and nACo coating on curved ball-end geometry. Zero coating built-up at ball-tip junction.
ZOLLER Radius Inspection
Ball radius, flute symmetry, and runout verified on ZOLLER Inspector before shipment. Certificate available on request.
4 Coating / Flute Variants
TiSiN 2F & 4F for steel · Uncoated 2F for aluminium & graphite · nACo 2F for HRC65 hardened steel.
Neck Relief for Deep Cavities
Neck diameter relief on long-reach variants reduces rubbing in deep mould cavities and eliminates tool deflection chatter.
MOQ 1 Piece
No minimum order. Standard sizes ship 1–5 days. Custom ball radii and lengths available in 5–15 days.
Need a Custom Ball Radius or Long-Neck Configuration?
We produce ball radii in 0.05mm increments, extended neck relief for deep-cavity access, and special coatings (AlCrN, DLC). Prototypes in 5–10 days.
