Freud/Diablo 16-522 1-1/4" Mortising Bit is engineered to deliver clean, precise mortises across plywood, veneer, solid wood, and virtually any composite material. Its down-shear design pushes wood fibers downward as the cut progresses, dramatically reducing tear-out and producing smooth, splinter-free results—perfect for doors, cabinetry, and furniture where precise hinge and hardware recesses matter.

• Diameter and purpose: 1-1/4" mortising bit tailored for standard hinge mortises and hardware recesses, ensuring consistent fit and alignment.
• Down-shear geometry: minimizes splintering on surface veneers and plywood by directing fibers down during the cut, preserving the appearance of the surrounding workpiece.
• Deep center gullets: optimize material removal and reduce chip loading, enabling smoother cuts and less heat buildup during deeper mortises.
• Versatility: ideal for mortising hinges and hardware, plus grooves and dadoes, making it a go-to choice for cabinetry, furniture frames, and door assemblies.
• Router compatibility: designed for use in both CNC routers and portable/handheld routers, giving you flexibility across projects and setups.

Use this bit for precise hinge mortises in cabinet doors, door frames, and furniture where alignment is critical. It excels at clean groove and dado work, helping you achieve tight joints without marring faces or edges. The combination of down-shear cutting and efficient material removal means you can tackle larger mortises with greater control and repeatability.

Pro tips for best results:

• Take multiple shallow passes rather than one deep cut to maintain control, reduce tear-out, and extend bit life.
• Secure the workpiece and use a straight guide to keep the mortise aligned with the hinge or hardware recess.
• Offer proper feed rate and ramping during entry and exit to minimize edge chipping, especially on veneered surfaces.

Whether you’re a seasoned carpenter or an enthusiast building refined cabinetry, the Freud/Diablo 16-522 1-1/4" Mortising Bit provides dependable, accurate mortises that ensure hinges sit perfectly and hardware sits flush—every time you work.
