- Total length of 2-21/32 in. - provides sufficient reach to mount slot cutter blades and stack configurations while keeping the tool assembly compact and well-balanced in the router.
- Relative length of 26mm - the working length of the arbor is sized to accommodate CMT 822 series slot cutter blades with proper clearance and secure blade engagement.
- Compatible with CMT 822 series slot cutters - purpose-built for CMT's slot cutter blade system, ensuring a matched fit and consistent performance without improvised adapters.

- If your router has a 1/2 in. collet and you need a dependable arbor for CMT 822 series slot cutter blades, this is the direct-fit solution - no adapters or workarounds required.
- The integrated bearing guide does the work of controlling cut depth along an edge, which simplifies setup and reduces the chance of inconsistent or off-depth slots across a workpiece.
- Built from steel, this arbor holds up to repetitive use in production routing environments, making it a practical choice for shops that run slot cutting operations regularly rather than occasionally.
