The CMT Slot Cutter Arbor with Bearing is a precision-machined steel arbor designed to mount CMT 822 series slot cutter blades securely in 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 stable, wobble-free platform for cutting clean, accurate grooves and slots in a wide range of wood and sheet materials. Whether you are setting up a biscuit joinery operation or routing decorative slots, this arbor delivers the consistent performance that precision woodworking demands.

Key Features

• Steel construction - a durable steel body withstands the torque and vibration of repeated slot cutting operations, helping the arbor maintain dimensional accuracy over time.
• Integrated bearing included - the bearing guide controls cutting depth and follows the workpiece surface, so you achieve consistent slot depth without additional setup tools or stop collars.
• 1/4 in. shank - fits a wide variety of handheld routers and router table collets that accept 1/4 in. tooling, making this arbor compatible with many existing shop setups.
• Right-hand (RH) rotation - engineered for standard right-hand router spindles, so the arbor threads securely and safely during operation without backing out.
• Total length of 2-13/32 in. - provides adequate clearance between the collet and the cutter blade, reducing the risk of the router base or collet nut interfering with the workpiece.
• 26 mm relative length (LB) - a carefully proportioned usable length gives you the right positioning for CMT 822 series slot cutter blades, keeping the cutter engaged at the correct working depth.
• Designed for CMT 822 series slot cutter blades - purpose-built compatibility means you get a precise fit with no adaptation required, reducing runout and improving slot quality.

Why This Product

• Purpose-matched to CMT 822 series blades - if you already own or plan to use CMT 822 slot cutter blades, this is the correct arbor designed specifically for that system, eliminating guesswork about fit and compatibility.
• Bearing guide built in - because the bearing is already included with this arbor, you do not need to source a separate pilot bearing or stop collar to begin routing slots, simplifying your setup.
• 1/4 in. shank broadens router compatibility - the smaller shank diameter means this arbor works in compact trim routers as well as full-size router tables, giving you flexibility across different machines in your shop.
• Steel body supports accurate, repeatable cuts - for joinery applications where slot alignment matters - such as biscuit joints or panel assembly - the rigid steel construction helps you achieve consistent results from the first pass to the last.
