Freud 16-106 1-1/4 Inch Down Shear Mortising Router Bit

The Freud 16-106 is a 1-1/4-inch overall diameter down shear mortising router bit engineered to machine clean, splinter-free hinge recesses, flat-bottom dadoes, and leveled CNC spoilboards. Built with a 1/4-inch shank and a 0.45-inch cutting height, this 2-cutter tool utilizes a down-shear cutting action that forces wood fibers downward to eliminate top-surface tearout. Tipped with TiCo™ Hi-Density Micrograin Carbide and protected by a heat-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, crisp-edged Mortises for cabinet hinges, lock faceplates, and architectural door 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 ensure uniform z-axis calibration across the entire cutting surface.

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.
  • Precision Dual-Flute Cutters: Two ground carbide cutters produce smooth, vibration-free passes across wide surface cutting widths.
  • 18,000 RPM Maximum Speed Limit: Precision-balanced body design enables stable, chatter-free rotation under demanding feed rates.

What's Included

  • (1) Freud 16-106 1-1/4" Down Shear Mortising Router Bit with 1/4" Shank

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.
