Maximize Production Speed with Flawless Chip-Free Finishes on Double-Sided Materials

The Freud 77-108 1/2" Single Flute Compression Bit is engineered for high-speed production environments where both finish quality and feed rate are critical. By utilizing a specialized combination of up-shear and down-shear flutes, this bit compresses the material fibers toward the center of the board, effectively eliminating chipping and tear-out on both the top and bottom surfaces of double-sided laminates and veneers. Its unique single-flute design allows for significantly faster routing than multi-flute alternatives, making it the premier choice for clearing material quickly in hardwood, softwood, plywood, or wood composites.

Built with Freud Premier Solid Carbide and enhanced by TiCo™ High-Density Carbide, the 77-108 is designed to withstand the rigors of heavy-duty production. The bit features Freud’s proprietary Black I.C.E. (Industrial Cooling Element) coating, which keeps the cutting edge cool and facilitates superior chip evacuation. This advanced combination delivers 2X the life and performance of standard uncoated bits. While optimized for high-performance CNC machinery, this versatile bit also delivers exceptional results in table-mounted or handheld routing applications.

Key Features

  • Dual-Sided Precision: Produces clean, chip-free top and bottom surfaces in double-sided veneers or laminated materials.
  • High-Speed Production: Single-flute geometry is specifically designed for fast routing and high feed rates.
  • Black I.C.E. Coating: Maintains a cool cutting edge and ensures superior chip evacuation to prevent burning.
  • TiCo™ High-Density Carbide: Specialized Freud carbide provides 2X increased tool life over standard bits.
  • Multi-Machine Versatility: Ideal for use on industrial CNC routers as well as handheld and table-mounted units.
  • Broad Material Range: Perfect for fast cutting in hardwood, softwood, plywood, and various wood composites.

Pro-Tip: To achieve the best "compression" action and prevent surface chipping, ensure your cutting pass is slightly deeper than the 11/32" upcut length. This ensures the down-shear portion of the bit engages the top surface of the board, forcing the fibers down and inward for a crisp, splinter-free edge on both sides.
