The CMT 852.502.11 Dado and Planer Bit is a professional-grade router bit engineered for smoothing rough surfaces, flattening baseboard profiles, and cutting wide, flat-bottom dadoes with precision and efficiency. Fitted with tungsten carbide tips and a downward shear angle, this 1 in. diameter bit delivers clean, consistent results across a broad range of wood and wood-composite materials. Its 1/2 in. shank provides a secure, vibration-free connection in both handheld routers and router table setups, making it a versatile choice for woodworkers who demand reliable surface planing and dado routing performance.

Key Features

• Tungsten carbide tips (HW material) - hard-wearing cutting edges hold their sharpness longer through demanding planing and dado routing tasks, reducing the need for frequent bit replacement.
• Downward shear angle - drives chips away from the workpiece surface, producing a cleaner, smoother cut with less tearout on wood faces and edges.
• 2-flute cutting geometry - balances cutting speed with surface quality, allowing efficient material removal while maintaining a smooth, flat bottom in dadoes and planed surfaces.
• 1/2 in. shank diameter - provides maximum rigidity and reduced vibration compared to smaller shanks, resulting in more accurate cuts and extended bit life.
• Right-hand rotation - compatible with the vast majority of routers and router tables used in woodworking shops, simplifying integration into existing setups.
• Also available with bearing - the bearing-guided version enables high-precision edge following and template work for projects requiring guided cuts, giving you flexibility to choose the right configuration for each job.
• Removes paint and enamel residues - useful for restoration and surface preparation work, not just raw wood applications, expanding the practical range of this bit beyond standard routing.

Why This Product

• Smoothing rough baseboard and uneven wood surfaces is a common challenge - this bit's carbide tips and downward shear geometry address that directly, delivering a flat, clean result without requiring multiple passes on a sander or hand plane.
• With a 3/8 in. cutting height and 1 in. diameter, this bit handles dado routing and surface planing in a single tool, reducing the number of bits needed in a woodworking setup.
• The ability to remove paint and enamel residues makes this dado and planer bit practical for renovation and restoration projects, not only new construction work with clean wood.
• For projects where precision guidance is critical, the option to choose a bearing-equipped version of the same bit means you can scale up to template-guided work without switching to an entirely different product line.
