CMT Dado and Planer Bit with Bearing - 3/4" Diameter, 3/8" Cutting Height, 1/4" Shank is a precision carbide-tipped router bit engineered for routing wide, flat-bottom dadoes and light surface planing tasks. Built by CMT with a 2-tooth right-hand rotation design and a downward shear angle, this bit pushes wood fibers down during the cut - delivering clean, splinter-free results in solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. The integrated bearing guide allows for accurate, repeatable depth control across a wide range of routing and mortising applications.

Key Features

• Thick Carbide Tips (HW - Hard Metal Carbide) - provides extended cutting life and durability when routing natural wood and wood composites, reducing the need for frequent bit replacement.
• Downward (Negative) Shear Angle Cutting Edges - pushes wood fibers down as the bit cuts, producing hinge mortises and dadoes with no splintered edges and smooth, flat bottoms for professional-quality results.
• 2-Tooth Cutting Configuration - balances cutting speed with surface finish quality, making the bit effective on both natural wood and engineered wood composites.
• Integrated Bearing Guide - maintains consistent cutting depth and follows template or workpiece edges accurately, supporting precise flat-bottom routing and dado work without additional setup.
• 1/4" Shank Diameter - fits a wide range of compact routers, handheld routers, and router tables, giving this bit broad machine compatibility.
• Right-Hand Rotation - compatible with standard router collets and motors, making setup straightforward on conventional handheld routers, router tables, and CNC routing machines.
• 3/4" Cutting Diameter x 3/8" Cutting Height - sized for routing dadoes and mortises that accommodate standard shelf, panel, and hinge hardware dimensions.
• 2-1/4" Total Length - compact overall profile provides stable cutting geometry and reduces deflection during use.

Why This Product

• The negative shear angle design actively suppresses tearout as the bit cuts, making it a strong choice for cabinetry, furniture, and hinge mortise work where a clean surface finish is required on the first pass.
• The thick carbide tips processed for industrial performance extend cutting life beyond standard bits, reducing downtime and replacement costs in production or repetitive routing tasks on both solid wood and composites.
• The bearing guide eliminates the guesswork in depth-of-cut control - woodworkers can rout dadoes and mortises consistently with a template or fence, saving time on layout and reducing material waste.
• The 1/4" shank and compact 2-1/4" overall length make this bit well-suited for use with popular mortising jigs and smaller router platforms, expanding versatility without requiring a large, high-horsepower machine.
