Product Description
The CMT Dado and Planer Bit - 1 1/4" Diameter x 5/8" Cutting Height with 1/2" Shank is a precision-ground routing bit engineered for smoothing rough surfaces, cleaning up baseboard edges, and creating wide, flat-bottom dadoes. Built with tungsten carbide tips and a downward shear angle, this right-hand rotating bit delivers clean, consistent cuts in solid hardwoods, softwoods, sheet goods, and even painted or enameled surfaces. Whether you are surface planing, routing dadoes, or stripping paint residue from reclaimed lumber, this CMT planer bit handles demanding tasks with control and efficiency.
Key Features
- Tungsten carbide tips (HW material grade) - provide long-lasting cutting performance and hold an edge through repetitive passes in hardwood and composite materials, reducing the need for frequent sharpening or replacement.
- Downward shear angle - directs cutting forces into the workpiece for cleaner surface results, reduced tearout, and a smoother finish on baseboard profiles and rough-sawn lumber.
- 2-flute cutting geometry - balances chip evacuation and cut quality, keeping the bit running cooler and reducing surface burn during extended planing passes.
- Paint and enamel removal capability - makes this bit a practical tool for stripping old finishes from reclaimed wood or previously painted surfaces without switching to a separate tool.
- Also available with bearing - for projects that require guided, high-precision edge planing where consistent depth of cut is critical.
- 1/2" shank diameter - provides a secure, low-vibration connection in standard router collets, which translates to more stable passes and a higher-quality surface finish.
Why This Product
- The combination of tungsten carbide tips and a downward shear angle makes this bit well-suited for smoothing baseboard and rough surfaces in a single controlled pass, eliminating the need for extra sanding or secondary processing steps.
- Its ability to remove paint and enamel residues means it serves double duty on reclaimed or previously finished wood, giving woodworkers and finish carpenters a versatile option without adding extra tooling to their collection.
- The 1 1/4" cutting diameter paired with a 5/8" cutting height is sized to handle practical dado and surface planing tasks on a handheld router or router table without overloading the router motor.
- The bearing-compatible design option means this bit can scale from freehand rough planing to guided precision work, covering a wider range of project requirements within the same tool family.

Frequently Asked Questions
What types of materials can this dado and planer bit cut?
This bit is designed for use in solid hardwood and softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. Its tungsten carbide tips handle both natural wood and engineered sheet materials effectively.
Can this bit be used to remove paint or enamel from wood surfaces?
Yes. According to the product specifications, this bit can be used to remove paint and enamel residues, making it useful for reclaimed wood projects or refinishing work where old finishes need to be stripped away before further processing.
Is a bearing version of this bit available?
Yes. CMT offers a bearing-equipped version of this planer bit for projects requiring high precision guided edge planing, where a consistent depth of cut relative to a reference surface is needed.
What shank size is required, and which machines are compatible?
This bit uses a 1/2" shank and is compatible with handheld routers, router tables, and CNC routing machines that accept a 1/2" collet. The 1/2" shank provides a stable, low-vibration connection for smooth surface planing and dado routing passes.
