TTR-001 · MILLING
Higher Tool Life and Feed Rate in Gearbox Housing Milling
OBJECTIVE
Compare insert performance in finish and semi-finish milling of a die-cast aluminum gearbox housing with bimetal features.
RECORDED RESULT
At the same cutting speed and depth of cut, the Premitools insert ran at a higher feed per tooth and recorded 55-60 parts per edge versus 40-45.

TTR-002 · TURNING
Stable Performance in 38CrMoAlA Injection Screw Turning
OBJECTIVE
Evaluate a Premitools grade against the incumbent insert in semi-finish and rough turning of an injection screw.
RECORDED RESULT
Both tools completed 14 recorded groove sequences. Operator feedback indicated slightly better performance from the Premitools option, although the difference was not large.
