Models and specificationsIs every listed bore offered in BT30?
No. The BT30 row lists SLA25. Check the exact interface row rather than extending the full family range to every size.
Can I replace an ER holder with this holder without further checks?
No. Verify the tool shank, retention method, reach and clearance because the clamping arrangements differ.
Does a larger shank mean a published heavy-cutting rating?
No cutting-load rating is supplied in this catalog. The complete machine, tool and holder setup requires review.
What should accompany an inquiry for a long version?
Provide the target gauge or overall length definition, spindle interface, shank drawing and clearance constraints.
