CMT part no:938.187.11
The smaller bearing on the CMT Beading bits makes a delicate inset at the base of the cut, giving you the advantage of an extra decorative option.
BE SURE to keep the black bearing washer right side up to correspond with the bearing rotation when reassembling the bearing. Improper reassembly can cause the bit to unscrew. All CMT roundover bits have a 12,7mm bearing diameter with the exception of the radius 28,6mm and 31,7mm bits which have a 19mm
bearing diameter. You have 13 different radii to choose from, the majority having 5 shank diameter options.
All bits are made of Fatigue Proof? steel and have carbide-tipped cutting edges.
