Product Description
The CMT 822.009.11 Two-Flute Slot Cutter is an industrial-quality, carbide-tipped routing bit engineered for precision slot cutting, groove routing, and inlay work in solid hardwood, softwood, timber, and composite wood materials. With a 1 1/4 in. cutting diameter and a compact 15/64 in. cutting height, this right-hand rotation cutter glides smoothly through dense and fibrous wood species, maintaining a sharp, clean edge even after multiple passes - making it an ideal choice for flooring installation, panel joinery, spline groove routing, and biscuit slot applications. Designed for use with a compatible slot cutter arbor (such as the CMT 891.517M), it fits seamlessly into both handheld router and router table setups for consistent, repeatable results.
Key Features
- Two-flute carbide-tipped (HW) construction - delivers clean, smooth cuts through solid wood and timber with minimal tearout, keeping edges sharp through extended use without frequent resharpening.
- 1 1/4 in. cutting diameter with 15/64 in. cutting height - sized precisely for flooring, inlay, and biscuit slot applications where a controlled, shallow groove is required.
- 8mm bore diameter - pairs directly with the CMT 891.517M slot cutter arbor, ensuring a secure, concentric fit for vibration-free operation at the router.
- Right-hand (RH) rotation - matches standard router motor direction so the cutter engages material correctly, reducing chatter and improving cut quality.
- Industrial-grade HW (hard metal/carbide) material - processed to industrial quality standards, meaning the carbide tips resist wear even when running repeatedly through dense hardwoods and engineered wood products.
- Smooth, efficient chip evacuation with two flutes - keeps the cutting zone clear of debris during passes through solid and timber wood, reducing heat buildup and extending cutter life.
Why This Product
- Built for flooring and inlay precision - the 15/64 in. cutting height and 1 1/4 in. diameter are sized specifically for flooring groove and inlay slot applications, giving woodworkers a purpose-matched tool rather than a general-purpose compromise.
- Stays sharp through repeated passes - the industrial-quality carbide tips are engineered to remain cutting-sharp even after several passes through solid hardwood and timber, reducing downtime spent on bit changes during long production runs.
- Designed for arbor compatibility - the 8mm bore is matched to the CMT 891.517M arbor, so setup is straightforward with no adapters or improvised solutions needed for a secure, wobble-free connection.
- Runs cleanly through demanding materials - the two-flute geometry moves efficiently through solid wood, plywood, and engineered panels, making it a practical choice for both workshop joinery and flooring installation where cut quality matters.

Frequently Asked Questions
What arbor does the CMT 822.009.11 slot cutter require?
This slot cutter has an 8mm bore and is designed for use with the CMT 891.517M slot cutter arbor. Pairing it with the correct arbor ensures a secure, concentric fit and vibration-free cutting performance.
What is the cutting height of this slot cutter, and what groove depth does that produce?
The cutting height is 15/64 in. This dimension defines the width of the slot or groove the cutter produces in a single pass, making it well suited for flooring splines, biscuit slots, and inlay channels of that specific width.
Can this slot cutter be used on a router table as well as a handheld router?
Yes. The CMT 822.009.11 is compatible with handheld routers, router tables, and CNC routing machines, giving woodworkers flexibility in how they set up for flooring, inlay, and panel joinery operations.
What materials can this carbide-tipped slot cutter handle?
The industrial-quality carbide-tipped (HW) construction allows this cutter to run smoothly through solid hardwood, softwood, timber, plywood, MDF, chipboard, laminates, melamine, and plastic, maintaining a sharp cutting edge even after several passes through dense or abrasive materials.
