CMT Reduction Bushing for Bearings 1/2" OD x 3/16" Bore
Series 799.01
Reduction Bushing
CMT 799.014.00 is the exact 1/2-inch outside-diameter variant in the official Series 799.01 reduction-bushing family. It reduces the bearing interface to a 3/16-inch bore—equivalent to 12.7 × 4.76 mm—for compatible CMT bearing-guided and rabbeting-set assemblies. Official CMT instructions show it in the 1/8-inch flush-trim and 1/2-inch rabbet configurations.
Main Product Description
CMT 799.014.00 is the exact reduction bushing in the official Series 799.01 Spare Parts and Accessories family. The North American row specifies D = 1/2 inch and B = 3/16 inch. CMT’s metric table lists the same configuration as D = 12.7 mm and B = 4.76 mm.
The bushing reduces the bearing interface so compatible CMT bearing-guided assemblies can mount on the specified 3/16-inch hardware. In CMT’s rabbeting-set instructions, reducer 799.014.00 is shown with washer 541.552.00 and screw 990.059.00 in both the 1/8-inch flush-trim and 1/2-inch rabbet arrangements.
The same official instructions cover imperial rabbeting-set items 835.001.11, 835.501.11, and 835.502.11, together with metric items 735.001.11, 935.001.11, 935.501.11, and 935.502.11. The reduction bushing is a separately orderable service component; the bearing, router bit, complete set, washer, screw, and shield are not included unless another CMT package explicitly states otherwise.
