Freud 16-108 1-1/4 Inch Down Shear Mortising Router Bit

The Freud 16-108 is a 1-1/4-inch overall diameter down shear mortising router bit engineered to cut smooth hinge pockets, flat-bottom dadoes, and leveled CNC spoilboards without surface tearout. Built with a heavy-duty 1/2-inch shank and a 1/2-inch carbide cutting height, this 2-cutter tool utilizes down-shear tip geometry to push top surface wood fibers downward into the cut. Tipped with TiCo™ Hi-Density Micrograin Carbide and protected by a thermal-resistant Perma-SHIELD® non-stick coating, it operates reliably at rotational speeds up to 18,000 RPM across CNC machinery, router tables, or handheld routers in solid hardwoods, softwoods, plywood, and veneers.

Best Used For:

  • Hinge & Hardware Mortising: Routing shallow, clean-edged mortises for door hinges, lock faceplates, and architectural cabinet hardware.
  • Flat-Bottom Dado & Groove Jointing: Machining wide, flat-bottomed dado channels and joinery slots in cabinet carcasses and shelving units.
  • CNC Spoilboard Surfacing: Flattening and resurfacing MDF CNC router beds to maintain uniform z-axis calibration across large cutting areas.

Key Performance & Safety Features

  • Down-Shear Cutter Geometry: Shear-angled carbide tips push surface wood fibers down to ensure a clean, tear-free top edge profile.
  • Deep Clearance Center Gullets: Deeply milled chip gullets allow fast waste evacuation to prevent thermal pitch buildup and chip loading.
  • TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide edges deliver exceptional durability and sharpness retention.
  • Perma-SHIELD® Non-Stick Coating: Protective red fluoropolymer coating guards against thermal friction, resin accumulation, and rust corrosion.
  • Heavy-Duty 1/2-Inch Shank: Rigid 1/2-inch steel shank diameter minimizes tool flex, runout, and cutter vibration during high-speed routing.
  • 18,000 RPM Maximum Speed Limit: Precision-balanced body design enables stable, chatter-free rotation under demanding feed rates.

Pro-Tip: Due to the down-shear angle pushing chips downwards into the pocket, make mortising passes using shallow depth increments to ensure chips clear freely out of deep mortises without pack-up.
