CMT Rabbeting Cutter Head - 4" Diameter, 3/4" Bore by CMT is a professional-grade shaper cutter head engineered for precise rabbeting operations on table shapers and industrial woodworking machines. With a 4" cutting diameter and a 3/4" bore, this heavy-duty cutter head delivers consistent, repeatable results across a wide range of wood species and engineered panel materials. Designed for production shops and serious woodworkers who demand accuracy in dadoing, rabbeting, and stepped-profile work, this tool pairs a solid carbide-tipped (HW) cutting platform with a generous 2" cutting height for deep, controlled stock removal in a single pass.

Key Features

• 4" Cutting Diameter - provides a wide cutting arc that reduces the number of passes needed and delivers cleaner, more consistent rabbets across your workpiece.
• 3/4" Bore (19.05mm) - fits standard 3/4" shaper spindles, making this cutter head directly compatible with most professional table shapers without adapters.
• 2" Cutting Height - allows deep material engagement in a single setup, reducing repositioning time and improving throughput on thicker stock.
• HW Carbide Cutting Material - tungsten carbide construction provides long-lasting edge retention on solid hardwood, softwood, and engineered panels, reducing the frequency of tool changes.
• 4 Spurs - multiple scoring spurs pre-score the wood fibers ahead of the main cutters, reducing tearout and producing clean-edged rabbets even across the grain.
• 2 Cutting Teeth - a two-tooth configuration balances cutting speed with chip clearance, maintaining efficient material removal without overloading the machine.
• 7,500 - 12,500 RPM Operating Range - a wide speed range gives operators flexibility to match spindle speed to the material being cut, optimizing both surface quality and tool longevity.

Why This Product

• The 4" diameter combined with a 2" cutting height makes this cutter head well-suited for production rabbeting and housing operations on thick solid wood components where a smaller tool would require multiple setups.
• The 3/4" bore specification ensures direct compatibility with standard industrial shaper spindles, eliminating the need for reducing bushings and maintaining true concentricity during operation.
• Carbide (HW) cutting edges maintain sharpness over extended production runs, making this cutter head a cost-effective choice for shops cutting abrasive materials like MDF or particleboard on a regular basis.
• The broad operating range of 7,500 - 12,500 RPM allows this cutter head to be dialed in precisely for different material types - slower speeds for dense hardwoods, higher speeds for softer or engineered materials - giving operators real control over cut quality.
