FAQ

Is this shank ring compatible with other Montabert models?
No — this part is engineered specifically for the HC109. It is not interchangeable with HC105, HC110, or other series due to critical dimensional and load-bearing differences.
What is the typical lead time for bulk orders?
Standard lead time is 3–5 business days for in-stock quantities; custom batches (≥50 pcs) ship within 12 working days with ISO-certified traceability documentation.
How often should the shank ring be inspected or replaced?
Inspect every 200 operating hours; replace at 500–800 hours depending on rock hardness and duty cycle — or immediately if visible deformation, cracking, or excessive play is observed.
Does this part meet OEM quality standards?
Yes — manufactured to Montabert’s original dimensional tolerances, material specs, and heat-treatment protocols; supplied with mill test reports and RoHS/REACH compliance certificates.
