CR-602-12
6 Flute Compression Composite Router
0.375-in Dia 6-Flute End Mill, 1-in LOC, 0.375-in Shank, 2.5-in OAL
Compression router geometry — clean edges on both faces of the laminate, 10-20X tool life.
- Compression geometry: up-shear flutes at the tip transition to down-shear flutes above, pressing both skins of the laminate inward so neither face frays or delaminates
- 4 flute on 1/4" diameter (CR-402-08), 6 flute on 3/8" and 1/2" diameters (CR-602-12, CR-602-16)
- Dedicated up-shear length per size: 3/16" on 1/4" dia, 1/4" on 3/8" and 1/2" dia
- Three finishes: uncoated, Black Widow DLC coated (-DLC), and Diamond Coated DCC (-D)
- Metric MCR line in 6mm (4 flute), 10mm and 12mm (6 flute) with 5-6mm upshear lengths
- 10-20X tool life with diamond coating
- Tolerances: cutting dia -.001/-.003, shank dia -.0001/-.0002, OAL +/-.060
- Runs dry, wet, cold air, or spray mist; slotting, side milling, helical interpolation, ramping through finishing

About this series
CR / MCR Compression Routers
4- and 6-flute compression routing for composites.
The CR Series is a 4- and 6-flute compression router (square end) for composites, with an up-shear/down-shear geometry. Available uncoated, Black Widow DLC coated, and diamond coated; metric MCR versions are also offered.
- 4- and 6-flute compression (up/down shear) geometry
- Available uncoated, Black Widow Diamond-Like Carbon (DLC) coated, and Diamond Coated (DCC)
- Inch (CR) and metric (MCR) sizes
Composites. Dry, Wet, Cold Air, or Spray Mist. Applications: slotting, side milling, helical interpolation, ramping, roughing, semi-finishing, finishing.
