Product Description
The CMT 824.130.00 Slot Cutter Arbor is a precision steel arbor designed to mount CMT 822 series slot cutter blades on routers equipped with a 1/2 in. shank collet. Built as a direct replacement arbor for use with the CMT 800.616 system, this component gives woodworkers and cabinetmakers a reliable foundation for groove cutting, slot routing, and biscuit joinery setup on handheld routers, router tables, and CNC routing machines. The M8mm threaded diameter and 3-13/16 in. total length provide a stable, consistent platform that keeps slot cutter blades properly aligned and wobble-free during operation.
Key Features
- 1/2 in. shank - fits standard 1/2 in. collet routers, making this arbor compatible with a wide range of handheld routers, router tables, and CNC routing machines without adapters or modifications.
- M8mm threaded arbor diameter - precisely sized threading ensures a secure, positive engagement with CMT 822 series slot cutter blades, reducing vibration and maintaining consistent groove depth across the full cut.
- 3-13/16 in. total length with 47mm relative length - provides adequate reach for mounting slot cutter blades at the correct cutting depth while keeping the tool assembly compact and manageable.
- Steel construction - a durable steel body withstands the rotational stress and cutting forces generated during repeated slot cutting operations, supporting long service life as a replacement arbor.
- Designed specifically for CMT 800.616 - engineered to integrate directly into the CMT 800.616 slot cutter system, eliminating guesswork around fitment and ensuring the arbor performs as the system intends.
- Replacement arbor for CMT 822 series slot cutters - provides a straightforward path to restoring a worn or damaged slot cutter assembly without replacing the entire tool, saving cost and downtime.
Why This Product
- When an arbor wears out or is damaged, replacing only the arbor rather than the full slot cutter assembly is the practical solution - this CMT 824.130.00 is the correct replacement component for the CMT 800.616 system, so the fit is exact and the original performance is restored.
- The 1/2 in. shank is one of the most widely used router collet sizes, meaning this arbor integrates cleanly into existing router setups on a router table, handheld router, or CNC routing machine without requiring additional tooling.
- Steel construction delivers the rigidity needed to keep CMT 822 series slot cutter blades running true, which directly affects groove quality and consistency in solid hardwood, plywood, MDF, and similar materials.
- With a total length of 3-13/16 in. and a 47mm relative length, this arbor is sized to work within the geometry of the CMT 800.616 slot cutter system, so blade positioning and cutting depth remain predictable from one job to the next.
