The CMT Dado and Planer Bit - 3/4" Diameter x 3/8" Cutting Height with 1/2" Shank is a precision-ground, carbide-tipped routing bit engineered for smoothing rough surfaces, removing paint and enamel residues, and cutting wide, flat-bottom dadoes. Built by CMT with a 2-tooth tungsten carbide tip design and a downward shear angle, this bit delivers clean, consistent results across solid wood, sheet goods, and composite panels. Whether you are using a handheld router, a router table, or a CNC machine, this planer bit gives you the control and surface quality needed for finish-ready work.

Key Features

• Tungsten carbide tips (HW material grade) - hard-wearing carbide edges maintain sharpness through repeated cuts in solid hardwood, softwood, plywood, MDF, and laminates, reducing the need for frequent resharpening.
• Downward shear angle geometry - pulls material downward during the cut to reduce tearout and produce smoother, cleaner surface finishes on rough or painted stock.
• 2-tooth configuration - balances feed rate and finish quality, giving you consistent chip evacuation and a flat, even surface on each pass.
• 3/4" cutting diameter with 3/8" cutting height - sized for wide dado work and surface planing passes without overloading the router motor.
• 1/2" shank diameter - the full 1/2" shank seats securely in standard router collets, minimizing vibration and improving cut accuracy during planing and dado routing operations.
• Right-hand rotation (RH) - compatible with standard router setups, ensuring correct bit engagement without special tooling or adapters.
• Paint and enamel removal capability - the robust carbide tips handle abrasive coatings that would quickly dull lesser bits, making this a practical choice for restoration and surface prep work.
• Also available with bearing - when high-precision edge-referenced work is required, the bearing version of this bit provides guided, repeatable cuts.

Why This Product

• This bit solves the challenge of achieving a smooth, flat surface on rough or coated stock - the downward shear angle and carbide tips work together to produce finish-ready results in a single pass rather than requiring multiple sanding or planing steps.
• Its ability to remove paint and enamel residues makes it a practical tool for renovation and restoration projects where other router bits would quickly wear out or chatter against hardened coatings.
• The 1/2" shank provides a rigid, low-vibration connection to the router, which translates directly into straighter dado walls and flatter planed surfaces compared to smaller-shank alternatives.
• With compatibility across handheld routers, router tables, and CNC routing machines, this bit adapts to the workflow you already have without requiring a dedicated machine setup.
