Product Description
The CMT 824.134.00 Slot Cutter Arbor is a precision steel arbor designed to mount CMT 822 series slot cutter blades, giving woodworkers and cabinetmakers a reliable, wobble-free platform for cutting consistent grooves, dados, and slots in a wide range of materials. With a 1/2 in. shank, this replacement arbor fits standard router collets and is purpose-built as a compatible arbor for the CMT 800.627 slot cutter assembly - making it an essential component for anyone setting up or rebuilding a slot cutter system.
Key Features
- Steel construction - machined from steel for rigidity and long-term durability, ensuring the arbor holds its geometry through repeated use without deflection that could compromise slot accuracy.
- 1/2 in. shank - fits the most common router collet size used in handheld routers, router tables, and CNC routing machines, making this arbor broadly compatible with professional and shop setups alike.
- M12 mm threading diameter - provides a secure, correctly sized thread interface for mounting CMT 822 series slot cutter blades, eliminating play or misalignment during cutting.
- 3-11/32 in. total length - delivers sufficient reach for stacking multiple blades or adding spacers between cutters, giving you flexibility when configuring custom slot widths.
- 39.5 mm relative length - the usable cutting-zone length supports proper blade seating and accurate depth positioning for repeatable slot results across workpieces.
- Designed as an arbor replacement for 822 series slot cutters - purpose-matched to CMT's own slot cutter ecosystem, so you can restore or expand an existing setup without guesswork or fitment issues.
- Compatible with CMT 800.627 - this arbor is the designated companion component for the 800.627 assembly, ensuring correct mechanical pairing and confident performance.
Why This Product
- When an arbor wears out or is lost, replacing it with the exact OEM-matched CMT 824.134.00 restores your slot cutter setup to factory specification - no adapting or improvising required.
- The 1/2 in. shank means this arbor drops straight into most professional routers and router table collets, reducing setup time and keeping your workflow moving.
- Steel construction provides the stiffness needed to resist vibration and flex during slot cutting, which directly translates to cleaner, more consistent groove walls in hardwood, softwood, plywood, and sheet goods.
- Because it is specifically engineered for the CMT 822 blade series and the 800.627 assembly, there is no uncertainty about blade compatibility - the thread pitch, diameter, and length are all matched to those components from the ground up.
