Main Product Description
CMT 800.622.11 is the exact imperial variant in the official 8/900.622 Adjustable Double Roundover Router Bits family. The verified row specifies D = 1-11/32 inches, T = 7/16 to 1-1/4 inches, R = 1/8 inch, L = 3-15/16 inches, S = 1/2 inch, and R1 = 5/64 inch.
The paired cutter assembly creates a double roundover treatment on wood panels. CMT identifies the profiles as 3 mm (1/8 inch) and 2 mm (5/64 inch), while interchangeable shims allow the assembly spacing to be adjusted for different board thicknesses. The official instructions cover examples from 11.1 mm (7/16 inch) through 31.75 mm (1-1/4 inches).
The 2026 CMT router-bit catalog identifies the family as HW Z2 RH. The official assembly drawing lists profile cutters 822.031.11 and 822.032.11, 1/2-inch arbor 824.137.00, bearing 791.037.00, M8 nut 990.020.00, assembly shields, and multiple precision spacers. The tool is intended for table-mounted routers and must not be used in hand-held power tools.

Compatibility & Installation Notes
Use CMT 800.622.11 only in a table-mounted router with a sound 1/2-inch collet; CMT specifically advises against hand-held router use. Select the official assembly sequence for the required 2 mm or 3 mm profile and board thickness. Keep cutters, spacers, bearing, shields, arbor shoulder, and M8 nut clean and seated flat. Confirm that the bearing turns freely, the workpiece is fully supported, the fence and guards are correctly positioned, and the cutter clears the table and surrounding hardware. Follow the router and tool manufacturers' speed, feed, and projection limits.

CMT 800.622.11 combines two HW carbide profile cutters, bearing guidance, a 1/2-inch shank, and shim-based adjustment for 7/16- to 1-1/4-inch panels.
The verified 1/8-inch and 5/64-inch radii, published service components, and table-router-only requirement define the complete operating envelope.
