Video below shows Torquata bits in action - also applicable to the CMT Range
You have 13 different radii to choose from, with the majority having 2 shank diameter options - 1/4in or 1/2in. All bits are made of Fatigue Proof® steel and have CMT's unique micro-grain carbide-tipped cutting edges - suitable for industrial applications.
All CMT roundover bits up to 25.4mm radius have a 12,7mm (1/2") diameter guide bearing whereas the beading bits come standard with a 9.5mm diameter bearing, creating the extra decorative lip.
Bits with 28,6mm and 31,7mm radii which have a 19mm diameter bearing.
