CMT Professional Finger Joint Bit is a precision-engineered router bit designed to create incredibly strong wood joints for cabinetry, furniture, and millwork applications. With a 1 7/8 in. cutting diameter and a 1/2 in. shank, this hardened carbide-tipped bit produces tight, accurate finger joints in solid hardwood, softwood, plywood, and other wood-based materials. Whether you are gluing boards side-to-side or joining them end-to-end, the interlocking profile maximizes glue surface area and delivers a bond that is actually stronger than the unworked wood itself - making it a go-to choice for woodworkers who demand lasting structural integrity from every joint.

Key Features

• Hardwood (HW) Carbide Cutting Material - industrial-grade carbide holds a sharp edge longer through dense hardwoods and composites, reducing the need for frequent resharpening and keeping cuts clean throughout the workpiece.
• 1 7/8 in. Cutting Diameter - produces a full-width finger profile in a single pass, supporting workpiece thicknesses from 1/2 in. up to 1 3/8 in. for versatile joint sizing without multiple setups.
• 5.56 mm Cutting Depth - the precisely machined finger profile creates deep interlocking teeth that maximize glue surface contact, yielding a joint that is stronger than the surrounding wood.
• 2-Flute Design with Right-Hand Rotation - dual cutting edges balance the cut, reduce vibration, and leave a smooth mating surface that fits together tightly with minimal tearout.
• 1/2 in. Shank - a full 1/2 in. shank provides superior rigidity and reduced runout compared to smaller shanks, translating to more accurate joints and longer bit life in both table-mounted and handheld router setups.
• Accommodates Material Up to 1 3/8 in. Thick - wide range of compatible thicknesses makes this bit practical for a broad variety of panel and solid-wood joint applications without changing tooling.
• Side-to-Side and End-to-End Joint Capability - versatile profile geometry allows woodworkers to tackle multiple joint orientations with a single bit, saving setup time and tooling cost.

Why This Product

• When structural integrity matters, the interlocking finger profile and maximum glue surface create a wood-to-wood bond that is stronger than an unworked piece of the same material - ideal for load-bearing panels, cabinet carcasses, and furniture frames.
• The wide thickness range of 1/2 in. to 1 3/8 in. means one bit handles the majority of common lumber and panel stock dimensions, reducing the need for multiple specialized bits on a project.
• The 1/2 in. shank combined with the 2-flute hardened carbide design delivers the stability and edge retention needed for precise, repeatable joints in both production environments and custom shops.
• At a total length of 3 13/16 in., the bit reaches comfortably into a router table fence setup or a handheld router guide, giving woodworkers flexibility across different machine configurations without sacrificing control.
