The CMT 824.061.00 Slot Cutter Arbor from CMT is a precision steel arbor designed to mount CMT 823 series slot cutter blades - the ones featuring a 45 deg. bore - onto routers equipped with a 1/4 in. shank collet. Sold without a bearing or stop collar, this arbor gives woodworkers a clean, straightforward mounting solution when bearing and collar components are already on hand or when a custom slot cutter assembly is being configured. Whether you are running a handheld router, a router table, or a CNC routing machine, this right-hand rotation arbor is built to deliver accurate, wobble-free performance on solid hardwood, softwood, plywood, MDF, and more.

Key Features

• Steel construction - provides the rigidity and durability needed to hold slot cutter blades securely under the rotational forces of router operation, minimizing deflection and extending tool life.
• 1/4 in. shank - fits standard 1/4 in. collets found on a wide range of handheld routers and router tables, making this arbor immediately compatible with compact and mid-size routing setups without adapters.
• 2 11/64 in. total length - provides adequate reach for mounting 823 series slot cutter blades while keeping the assembly compact enough for controlled depth and clearance in tight workpiece situations.
• Right-hand (RH) rotation - matches the standard direction of rotation for most routers, ensuring proper blade engagement and chip ejection when cutting slots and grooves.
• Designed for CMT 823 slot cutters with 45 deg. bore - purpose-built compatibility means the arbor and blade seat together precisely, reducing runout and producing clean, consistent slot cuts in wood and sheet materials.
• Sold without bearing or stop collar - ideal for builders assembling a custom slot cutter setup who already have bearing and collar components, avoiding redundant parts and keeping costs focused on what is actually needed.

Why This Product
