Product Description
The CMT 824.064.00 Slot Cutter Arbor without Bearing is a precision steel arbor designed to mount CMT 822 series slot cutter blades onto handheld routers, router tables, and CNC routing machines. With a 1/4 in. shank and a total length of 2-13/32 in., this right-hand rotation arbor provides a secure, stable connection between your router and your slot cutting blades - giving you consistent, wobble-free grooves in wood, sheet goods, laminates, and more. The non-bearing design suits setups where a separate bearing or depth stop is already part of the assembly.
Key Features
- Steel construction - durable material delivers long service life under the repeated clamping forces and lateral loads typical of slot cutter operations.
- 1/4 in. shank - fits a wide range of compact and full-size routers with a 1/4 in. collet, making this arbor broadly compatible with common workshop and job-site machines.
- Total length of 2-13/32 in. - provides enough reach for proper blade seating and secure collet engagement without excessive overhang that could introduce vibration.
- Relative length (LB) of 26mm - the usable cutting zone is sized to accept CMT 822 series slot cutter blades cleanly, keeping the stack properly positioned for accurate groove depth.
- M8mm thread diameter - standardized thread engages slot cutter blade hardware securely, reducing the risk of loosening during extended cutting runs.
- Right-hand (RH) rotation - matches standard router spindle direction so the arbor tightens naturally during operation, preventing self-loosening under load.
- Without bearing design - intended for use with CMT 822 series slot cutters in configurations where depth is controlled externally, giving experienced operators flexibility in their setup.
Why This Product
- Specifically engineered as an arbor for CMT 822 series slot cutter blades, this component ensures dimensional compatibility right out of the box - no guesswork about thread pitch, length, or blade fit.
- The M8mm thread and steel body hold slot cutter blades firmly during right-hand rotation, reducing runout and helping produce clean, consistent grooves in solid wood, plywood, MDF, and laminates.
- The 1/4 in. shank keeps the arbor accessible to a broad range of routers - from compact trim routers to full-size plunge routers - without requiring a separate collet reducer.
- Choosing the non-bearing version allows you to pair this arbor with your own bearing selection or depth control method, making it a practical choice when you already have bearing components on hand or are building a custom slot cutter stack.

Frequently Asked Questions
Which blade series is this arbor designed to work with?
This arbor is specifically designed for use with CMT 822 series slot cutter blades. The M8mm thread diameter and 26mm relative length (LB) are sized to properly seat and retain those blades during right-hand rotation cutting operations.
Does this arbor include a bearing?
No - this is the without-bearing version of the CMT slot cutter arbor. It is intended for setups where depth of cut is controlled by an external method or where the operator is assembling a custom configuration using separately sourced bearing components.
What router collet size is required to use this arbor?
This arbor has a 1/4 in. shank, so it requires a router equipped with a 1/4 in. collet. It is compatible with handheld routers, router tables, and CNC routing machines that accept a 1/4 in. collet.
What is the total usable length of this arbor?
The arbor has a total length of 2-13/32 in. and a relative length (LB) of 26mm. The relative length represents the portion of the arbor available for blade mounting, while the total length accounts for the full body including the 1/4 in. shank section that seats in the router collet.
