How do I choose between these Laydown LSA holders?
Check shank height and width, tool length, cutting height and F dimension against the machine turret and required reach.
Does an inch listing mean every insert uses an inch thread form?
The holder’s native dimension system does not determine thread form or insert compatibility. Match the exact seat, hand, insert catalog number and required thread standard.
What should I include in a quote request?
Include the exact holder material number, quantity and required insert or replacement-part references. Available holder configurations are LSASR103 (1281801), LSASR123 (1281802), LSASR163 (1281803), LSASR203 (1281805).
