The CMT Reverse Glue Joint Bit - 1-3/4" Diameter x 1-1/4" Cutting Height, 1/2" Shank is a precision-engineered routing tool designed to produce virtually indestructible glue joints in solid wood panels, cabinet doors, and wide furniture pieces. With a right-hand rotation profile and a 2-tooth tungsten carbide-tipped (HW) cutting head, this bit delivers flawlessly matched reverse cuts that interlock with exceptional accuracy - making it a go-to choice for woodworkers who demand tight, clean panel joints without the guesswork.

Key Features

• Reverse glue joint profile - produces a unique interlocking joint geometry that creates a larger glue surface area, resulting in a virtually indestructible bond that dramatically outperforms simple edge-to-edge butt joints in panel and door assembly.
• Simple flip-and-run technique - run one edge of the panel, turn the panel over, and route the opposite edge to create perfectly symmetrical, harmonized reverse cuts that match up without any additional setup or adjustment.
• Accurate bit centering design - the upper and lower vertical cutting edges cut equal proportions when the bit is centered to the wood thickness, ensuring balanced, mirror-image profiles for a clean, seamless joint line every time.
• 2-tooth HW carbide construction - tungsten carbide-tipped cutting edges deliver extended service life and clean, smooth cuts through solid hardwood and other wood composites, reducing tearout and minimizing surface prep after routing.
• 1/2" shank diameter - the heavy-duty shank provides superior stability and vibration damping during routing, reducing chatter and improving cut quality in both handheld router and router table applications.
• Maximum material thickness range of 19/32" to 1-3/16" - accommodates a practical range of panel and door stock thicknesses commonly used in cabinet and furniture construction, giving you flexibility across multiple project types.
• Right-hand rotation - compatible with standard router spindle direction, ensuring immediate drop-in compatibility with the vast majority of handheld routers and router tables without any special adapters or settings.

Why This Product

• Engineered for wide panels and doors - the reverse glue joint profile is specifically suited to routing wide dimension panels, cabinet doors, and furniture pieces where a strong, self-aligning joint is critical to long-term structural integrity.
• No complex jigs or fixtures required - the flip-and-run routing method is built into the bit's geometry, allowing a single 1/2" shank setup on a standard router table to produce a perfectly matched joint without specialty clamping systems.
• Wider gluing surface for a stronger bond - compared to a straight edge joint, the interlocking profile created by this bit increases the total glue contact area, which means the joint holds under stress even in demanding furniture and door applications.
• Handles a range of stock thicknesses - with a working thickness range from 19/32" to 1-3/16", this bit is well-matched to common hardwood panel and cabinet door stock, eliminating the need to switch bits when moving between standard lumber dimensions.
