The CMT 823.364.11 Slot Cutter is a precision-engineered 3-flute carbide-tipped routing bit designed for clean, accurate slot cutting in woodworking and panel joinery applications. With a 1 7/8 in. cutting diameter, a 1/4 in. kerf width, and an 8mm bore, this right-hand rotation cutter is built to handle spline grooves, biscuit slots, panel connector recesses, and T-slot routing across a wide range of wood-based and composite materials. Sold without an arbor, it pairs with compatible CMT arbor assemblies to give woodworkers and cabinetmakers precise control over slot depth and placement.

Key Features

• 3-Flute Carbide-Tipped (HW) Cutting Edges - three hardmetal carbide flutes distribute cutting load evenly, reducing vibration and delivering smoother slot walls in a single pass through hardwood, softwood, plywood, MDF, and sheet goods.
• 1/4 in. Kerf Width - matches standard spline stock and panel connector dimensions precisely, eliminating the need for multiple passes or secondary fitting adjustments.
• 1 7/8 in. Cutting Diameter - sized for both handheld router and router table use, providing ample material removal capacity while remaining compact enough for controlled plunge entry.
• 8mm Bore Diameter - fits CMT and compatible arbor systems with an 8mm shaft, making it straightforward to integrate into existing router setups without adapter modifications.
• Right-Hand Rotation - designed for standard router motor direction, ensuring safe, predictable feed behavior and consistent chip ejection away from the finished surface.
• 0.177 in. Plate Thickness - a robust cutter body supports the carbide teeth under lateral cutting stress, maintaining dimensional accuracy across extended production runs.
• Sold Without Arbor - lets the user select the arbor length and bearing configuration that best suits the specific application, giving flexibility for different slot depths and material stacks.

Why This Product

• The 1/4 in. kerf precisely matches common spline and panel connector stock dimensions, which means slots fit on the first pass without secondary trimming or shimming - saving setup time on production runs.
• The 3-flute hardmetal carbide geometry cuts cleanly through hardwood, softwood, MDF, plywood, and composite sheet goods, making this a single cutter that covers most panel joinery material types a woodworker or cabinetmaker encounters.
• The 8mm bore and arbor-free design give the buyer direct control over arbor length and bearing selection, allowing the same cutter to be configured for shallow biscuit slots, deeper spline grooves, or Striplox-style connector recesses.
• Right-hand rotation and a balanced 3-flute layout reduce chatter and lateral deflection, which translates to straighter, more consistent slots - especially important when aligning panel connectors or fitting splined miters.
