CMT 791.007.00 is the exact metric bearing item in the official Series 791 Spare Parts and Accessories family. The European variation row specifies a 19 mm outside diameter, 6 mm bore, and 6 mm width. The North American row lists the same bearing as 3/4 inch outside diameter with a 6 mm bore and 6 mm width.
The bearing functions as a guide, profile-control, or flush-trim component on compatible CMT router-bit assemblies. Verified official references include selected Series 657 flush-trim and pattern bits, Series 661 roundover insert bits, 7/851B bowl-and-tray bits, 7/901B mortising bits, 7/906 flush-trim bits, 7/907 bevel-trim bits, 7/914B round-nose bits, 7/915B V-grooving bits, 7/948B plunge-ogee bits, and 7/965B classical-bead bits.

Related components vary by tool family and exact item row. CMT’s Series 791 safety guidance requires the black shield to remain right side up during reassembly so the shield orientation corresponds with bearing rotation.
