CMT 800.616.11 Finger Joint Router Bit by CMT is a professional-grade carbide-tipped cutting tool engineered for woodworkers who demand strong, precise interlocking joints. With a 1 7/8" cutting diameter and 1/2" shank, this finger joint bit excels at creating tight side-to-side and end-to-end wood joints in material up to 1 9/16" thick - producing a glue surface so accurate that the finished joint is actually stronger than the unworked wood itself.

Key Features

• 1 7/8" Cutting Diameter with 3-Tooth Configuration - the wide diameter and 3-flute geometry distribute cutting forces evenly, delivering smooth, chatter-free cuts that require minimal cleanup before glue-up.
• Hardwood (HW) Carbide-Tipped Cutting Material - industrial-grade carbide tips maintain a sharp edge through demanding cuts in solid hardwood, softwood, plywood, MDF, and similar sheet goods, extending the usable life of the bit between sharpenings.
• Right-Hand (RH) Rotation - matches the standard spindle direction of handheld routers, router tables, and CNC routing machines, ensuring safe, stable operation without any adapter or modification.
• 9.53mm Cutting Depth per Pass - precisely sized flutes cut consistent finger profiles in a single pass, eliminating the need for multiple setups and keeping production time low.
• Finger Joint Range of 1/2" to 1 3/8" - accommodates a variety of board thicknesses and joint configurations, making this bit a versatile choice for cabinet making, furniture building, and structural woodworking projects.
• Maximum Material Thickness of 1 9/16" - handles typical dimensional lumber and panel stock thicknesses in a single setup, reducing the complexity of multi-pass routing workflows.
• 3 13/16" Total Length with 1/2" Shank - the full-length shank provides a secure grip in standard router collets, minimizing vibration and runout for repeatable, accurate joint profiles.
• Versatile Side-to-Side and End-to-End Joinery - the finger joint profile maximizes glue surface area across the mating faces, creating an assembly that is structurally stronger than the base wood, ideal for box construction, edge-gluing panels, and length-extension joints.

Why This Product

• For woodworkers who need a structurally superior joint without complex jig setups, this finger joint bit creates an interlocking profile that maximizes glue surface contact - making the joined assembly stronger than the surrounding wood.
• The 1/2" shank size keeps the bit firmly seated in router table and handheld router collets, reducing the vibration that causes inconsistent finger profiles and misaligned joints at glue-up time.
• With capacity for material up to 1 9/16" thick and a joint length range spanning 1/2" to 1 3/8", this bit covers the dimensions most commonly encountered in cabinet carcass work, furniture panel glue-ups, and structural lumber extensions - without switching tools.
• The hardwood-grade carbide cutting edges retain their sharpness through production runs in dense species and composite materials, meaning fewer stops for sharpening or bit changes across a full workday.
