TYPICAL USES :
For high speed production of repition work (e.g. manufacture of bushes, pins, bolts, nuts, studs and couplings) where the major requirements are rapid
machining and maximum tool life.
Cutting speeds on bright drawn free-cuttings steel bar are considerably above those of ordinary mild quality steel and components are produced of
similar mechanical properties with a far superior surface finish.
