Product Description
CMT Two-Flute Slot Cutter - 1-7/8" Diameter, 12mm Bore is a professional-grade carbide-tipped routing tool engineered for precision slotting in solid hardwood, softwood, plywood, MDF, and composite panels. Designed for use with a compatible slot cutter arbor such as the CMT 800.606 series, this cutter delivers clean, accurate grooves for biscuit joinery, spline routing, panel assembly, and inlay work. Its right-hand rotation and two-flute configuration produce smooth cutting action with reduced tear-out, making it a reliable choice for woodworkers and cabinet makers who demand consistent results across high-volume production or fine finish work.
Key Features
- Two-Flute Design (Z=2) - dual cutting edges distribute load evenly across the workpiece, producing cleaner slot walls and reducing vibration during the cut for a smoother finished groove.
- 1.85mm Cutting Height - a precise, narrow kerf depth suited for thin spline slots, biscuit grooves, and inlay channels where tight dimensional accuracy is critical.
- HW Carbide-Tipped Construction - hard metal carbide tips maintain sharpness through repeated passes in solid timber, engineered wood, and flooring materials, reducing the need for frequent resharpening or replacement.
- 12mm Bore Diameter - mates directly with the CMT 800.606 arbor system, ensuring secure, concentric mounting and eliminating wobble during high-speed operation.
- Right-Hand Rotation (RH) - compatible with standard router motor direction, allowing seamless use on handheld routers, router tables, and CNC routing machines without setup changes.
- 1-7/8" (47.6mm) Overall Diameter - a mid-range diameter that balances cutting reach with stability, making it effective for both edge slotting and field cuts in panel joinery applications.
Why This Product
- The industrial-quality carbide construction stays sharp even after several passes through dense solid hardwood or fibrous engineered panels, lowering long-term tooling costs in production environments.
- Matched to the CMT 800.606 arbor with a 12mm bore, this cutter integrates into an established system of interchangeable components - letting you swap cutter thicknesses without purchasing a new arbor each time.
- At just 1.85mm cutting height, this tool is purpose-built for the narrow groove work required in flooring, inlay, and spline joinery - applications where oversized cutters would cause material waste or structural weakness.
- Right-hand rotation and a two-flute geometry make this cutter straightforward to use on router tables and handheld setups alike, reducing setup complexity while still delivering a consistent, repeatable slot.

Frequently Asked Questions
What arbor is required to use this slot cutter?
This cutter is designed for use with the CMT 800.606 arbor series. The 12mm bore diameter matches that arbor system directly, providing a secure and concentric fit for accurate, vibration-free cutting.
What is the slot thickness this cutter produces?
The cutting height of this cutter is 1.85mm, so it produces a groove approximately 1.85mm wide. This narrow kerf makes it ideal for thin splines, decorative inlays, and precision joinery where tight-fitting slots are required.
What materials can this slot cutter handle?
The carbide-tipped (HW) construction allows this cutter to run smoothly through solid hardwood, softwood, plywood, MDF, and other engineered wood panels. The cutting edges remain sharp even after multiple passes through dense or abrasive materials.
Can this slot cutter be used on a CNC routing machine?
Yes. With its right-hand rotation and two-flute carbide construction, this cutter is compatible with handheld routers, router tables, and CNC routing machines. Verify that your machine spindle and arbor setup accept a 12mm bore cutter before mounting.
