Freud Mortising Router Bit 16-104 1/4 Shank 3/4 Inch (Down Shear TiCo Carbide Door Hinge Inlay Dado Flat Bottom Wood Milling CNC Hand Tool Unit)

Freud 16-104 3/4" Down Shear Mortising Router Bit with 1/4" Shank

The Freud 16-104 3/4-inch mortising router bit cuts flat-bottomed hinge mortises, hardware inlays, shallow dados, and blind grooves across hardwoods, cabinet-grade plywood, delicate veneers, and composite panels. Engineered with an aggressive down shear cutter angle that pushes surface wood fibers downward into the cut to eliminate edge splintering and tear-out, this 1/4-inch shank bit operates safely up to 24,000 maximum RPM. Outfitted with micro-grain carbide cutting edges, deep waste-clearing center gullets, and Freud's heat-resistant Perma-SHIELD non-stick coating, it equips custom cabinetmakers, architectural door installers, and CNC millwork technicians with smooth, chatter-free recess routing across handheld routers, router tables, and automated CNC spindles.

Best Used For:

• Door Hinge and Hardware Recess Routing: Mortising clean, perfectly flat-bottomed hinge pockets and lock faceplates in passage doors and cabinet jambs without surface blow-out.
• Delicate Veneer and Plywood Dadoing: Slicing crisp shallow dados and rabbets through pre-finished cabinet veneers and Baltic birch plywood with zero edge chipping.
• CNC Inlay and Signmaking Pockets: Clearing wide, flat-bottomed background fields and shallow inlay cavities cleanly using automated CNC toolpaths.

Key Performance & Safety Features

• Anti-Tearout Down Shear Geometry: Angled cutting flutes direct downward shearing pressure across workpiece surfaces, preventing grain lifting and splintering on delicate veneers.
• Deep Center Waste Gullets: Engineered flute relief evacuates wood chips and dust rapidly from enclosed mortises, eliminating thermal friction and scorching.
• Micro-Grain Carbide Cutting Edges: Premium carbide formulation retains razor-sharp cutting margins through abrasive glues, composite binders, and dense hardwoods.
• Perma-SHIELD Non-Stick Thermal Barrier: Proprietary red coating resists frictional heat buildup, resin pitch accumulation, and atmospheric corrosion.
• Multi-Machine Drive Compatibility: Precision-ground 1/4-inch shank ensures concentric runout control across CNC collets, handheld plunge routers, and router tables.

Technical Specifications

Pro-Tip: When routing door hinge mortises with a template guide, make multiple shallow passes rather than a single deep cut; this allows the deep center gullets to clear chips efficiently and produces an exceptionally flat base for flush hardware mounting.
