(4) Long service life through use of stud cutting edges
Because of the uniquely shaped cutters specially developed by HITACHI, each cutter has four (front, back, upper,
and lower) which can be used in turn for cutting studs. Each cutter is made of high wear-resistant, special steel,
and is capable of cutting up to 500 studs with each of its cutting edges. Accordingly, up to 2,000 studs can be cut
with appropriate use of the four cutting edges.
Four cutting edges
(5) Excellent working efficiency
In conventional cutting with a cut-off machine or disc grinder, considerable time is required for deburring after the
studs have been cut. In actual tests, the Model CL 10SA is approximately three times more efficient than cut-off
machines or disc grinders.
