Freud 75-100 1/8-Inch Solid Carbide Up Spiral Router Bit with 1/4-Inch Shank

The Freud 75-100 1/8-Inch Up Spiral Router Bit executes precision mortising, blind grooving, and deep plunge routing across hardwoods, cabinet-grade plywood, and dense composites. Manufactured from proprietary TiCo Hi-Density solid carbide with a Black I.C.E. ceramic coating, this 2-flute cutter withstands spindle speeds up to 24,000 RPM while reducing thermal friction and chip packing. Its continuous up-spiral flute geometry lifts waste upward away from the cut zone, delivering smooth, tear-free bottom finishes in table-mounted, handheld, and high-speed automated CNC routers.

Best Used For:

  • Deep Mortise & Blind Grooving: Clearing tight 1/8-inch mortise pockets and structural joinery slots in solid maple and oak without chip buildup.
  • Automated CNC Sheet Fabrication: Profiling intricate nesting patterns, inlays, and through-cut contours in Baltic birch plywood and MDF panels at 24,000 RPM.
  • Cabinet Joinery & Dado Routing: Milling clean-bottomed channel dados and inlay grooves using plunge router bases and precision router tables.

Key Performance & Safety Features

  • TiCo Hi-Density Solid Carbide: Custom-formulated micro-grain titanium cobalt carbide maintains extreme cutting edge sharpness under heavy continuous production feed rates.
  • Black I.C.E. Thermal Barrier: Industrial cooling element coating resists resin buildup, reduces pitch adhesion, and delivers up to 2X extended cutting life.
  • Continuous Up-Spiral Fluting: Aggressively pulls hot chips upward out of deep mortises and grooves to prevent workpiece burning and bit deflection.
  • Precision-Ground 1/4-Inch Shank: Ensures zero rotational runout and rigid clamping in standard collets to prevent chatter in high-speed router spindles.
  • High-Speed 24,000 RPM Rating: Dynamically balanced 2-cutter profile delivers ultra-smooth surface finishes at high industrial feed velocities.

What's Included

  • (1) Freud 75-100 1/8-Inch Up Spiral Solid Carbide Router Bit (1/4-Inch Shank)
