CMT Dado and Planer Bit - 3/4" Diameter x 3/8" Cutting Height, 1/4" Shank is a precision-ground, tungsten carbide-tipped routing bit engineered for smoothing rough surfaces, cutting wide flat-bottom dadoes, and removing paint or enamel residues from baseboards and workpieces. Featuring a right-hand rotation, a downward shear angle, and two carbide-tipped cutting edges, this bit delivers clean, controlled material removal in solid hardwoods, softwoods, plywood, MDF, and composite sheet goods. Whether mounted in a handheld router, a router table, or a CNC routing machine, this dado and planer bit gives woodworkers a reliable tool for surface planing and wide groove work. A version with bearing is also available for projects requiring guided, high-precision routing.

Key Features

• Tungsten Carbide Tips (HW Material) - industrial-grade carbide cutting edges hold a sharp edge longer under heavy use, reducing downtime for resharpening and delivering consistent results across hardwoods, softwoods, plywood, MDF, and laminates.
• Downward Shear Angle - directs cutting forces downward into the workpiece, producing a smoother surface finish on baseboard and rough-sawn lumber with fewer tearout marks and less post-processing needed.
• 2-Flute Cutting Geometry - dual carbide tips balance chip evacuation and surface quality, making this bit effective for both flat-bottom dado routing and light surface planing in a single tool.
• 1/4" Shank Diameter - fits standard 1/4" collet routers commonly found in handheld and benchtop setups, giving a wide range of woodworkers direct access to this bit without adapters.
• 3/4" Cutting Diameter x 3/8" Cutting Height - these proportions are well suited to cutting shelf dadoes, housing joints, and planing passes on narrow stock in a single router pass.
• Paint and Enamel Removal Capability - the robust carbide tips and shear geometry allow this bit to cut through paint and enamel residues on reclaimed or previously finished wood, expanding its use beyond raw lumber work.
• Also Available with Bearing - for edge-guided or template-following applications where consistent depth and lateral control are critical, a bearing-equipped version of this bit is available.
• Right-Hand Rotation (RH) - compatible with the standard rotation direction of virtually all handheld routers and router tables, ensuring straightforward setup and safe operation.
• 2-1/4" Total Length - a compact overall length keeps the bit stable and well-supported in the collet, reducing vibration during cuts and contributing to cleaner results.

Why This Product

• This bit handles two demanding tasks - dado routing and surface planing - in a single compact tool, reducing the need to swap bits between operations when smoothing baseboards or cutting housing joints.
• The tungsten carbide tips and downward shear angle work together to produce a notably clean surface on both raw and previously finished wood, making this a practical choice for renovation and restoration work where paint or enamel residues are present.
• The 1/4" shank makes this bit accessible to woodworkers using compact or trim routers as well as full-size routers with a 1/4" collet, broadening its compatibility across common shop setups.
• For projects requiring guided cuts along an edge or template, a bearing-compatible version is available - giving users a clear upgrade path when precision demands increase beyond freehand routing.
