Freud Mortising Router Bit 16-109 15/32 Inch Down Shear (1/2 Inch Shank TiCo Carbide Perma-SHIELD 24000 RPM Plywood Hardware Grooves Dadoes)

Freud 16-109 15/32 Inch Down Shear Mortising Router Bit

The Freud 16-109 is a 15/32-inch overall diameter down shear mortising router bit engineered to cut undersized 1/2-inch plywood grooves, hinge pockets, and flat-bottom dadoes without surface splintering. Built with a heavy-duty 1/2-inch shank and a 1/2-inch carbide cutting height, this 2-flute tool features down-shear cutter geometry that forces top wood fibers downward to eliminate tearout. Tipped with TiCo™ Hi-Density Micrograin Carbide and coated with thermal-resistant Perma-SHIELD® non-stick coating, it operates stably at rotational speeds up to 24,000 RPM across CNC machinery, router tables, or handheld routers in plywood, veneers, and solid timber.

Best Used For:

• Undersized 1/2-Inch Plywood Dadoing: Milling precise 15/32-inch wide dado grooves to achieve snug mechanical joints with modern undersized nominal 1/2-inch sheet goods.
• Cabinet Hardware & Hinge Mortising: Routing clean, flat-bottom mortises for cabinet faceplate hardware, recessed brackets, and door hinges.
• Fine Veneer & Laminate Slotting: Cutting tearout-free channels and joinery slots across delicate surface veneers and laminated timber panels.

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.
• 24,000 RPM Maximum Speed Limit: Precision-balanced body design enables stable, chatter-free rotation under demanding feed rates.

Technical Specifications

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.
