Foos Nano Flush Cut Router Bits - 1/4" Shank
Foos Nano Flush Cut Router Bits - 1/4" Shank
Part #: FB-3674
- TRIM FLUSH TO A TEMPLATE: The guide bearing rides your template or edge so the spiral cutter trims stock flush and copies patterns accurately.
- MANY MATERIALS: Solid carbide spiral flutes trim cleanly in hardwood, softwood, plywood, MDF, laminate and veneer, plus acrylic, PVC, ABS and other plastics.
- FITS YOUR MACHINE: 1/4 inch shank fits most trim routers, palm routers and router tables with a 1/4" collet.
- FOOS NANO COATED: The coating cuts friction, so the bit runs cooler, resists pitch and resin buildup, and holds a sharp edge longer than an uncoated bit. Less cleanup between jobs.
- USA VETERAN-OWNED SUPPORT: US veteran-owned FOOS has sold router bits on Amazon for 10 years. Message us and a real person answers. Every bit is laser-engraved with FOOS and its part number.

FOOS Nano coating: the coating reduces friction at the cutting edge, so the bit runs cooler, resists pitch and resin buildup, and holds a sharp edge longer.
