All dimensions in mm. Custom diameters (0.1mm increment), special flute counts, and extended lengths available on request.
Manufacturing Standard
Precision on Every Axis
Walter CNC 5-Axis Grinding
Every tool precision-ground on Walter Ewag 5-axis centres. Corner geometry and flute profile held to ±0.003mm.
Oerlikon Balzers Coatings
TiSiN and nACo coatings applied via Swiss Balzers PVD process. Uniform coating thickness on all cutting edges.
ZOLLER Inspection
Diameter, runout, corner radius, and flute symmetry measured on ZOLLER Inspector before shipment.
5 Coating / Flute Variants
TiSiN 2F & 4F for steel · Uncoated 2F & 3F for aluminium · nACo 4F for HRC65 hardened steel.
Ultra-Fine Grain Carbide
10% cobalt binder, grain size < 0.5µm — highest fracture toughness at micro-diameters.
MOQ 1 Piece
No minimum order. Standard sizes ship 1–5 days. Custom diameters and lengths in 5–15 days.
Need a Custom Diameter, Helix, or Coating?
We manufacture to 0.1mm increment, custom helix angles (30°/35°/45°), AlCrN, DLC, or uncoated variants, and special OAL. Prototypes in 5–10 days.
