16 mm Dia. Carbide Boring Bar, Capto C4 Shank, DCMT 21.5, Right Hand

16 mm (0.630") carbide bar on a Capto C4 shank. Reaches 67.3 mm (2.650") into the bore before the body widens — about 4xD; 90 mm (3.543") from the Capto clamping face to the cutting edge. Carbide bar shrink-fitted into the steel Capto flange — about three times stiffer than steel, for finish boring where a steel bar starts to chatter. 93° lead, DCMT 21.5 insert held by a screw, bores from 0.787" (20 mm). Through-coolant to the insert. Insert sold separately.
