SDS-max / SDS-plus adapter
HERMAN DC-90
For SDS-max drill hammers

Reversible adapter for SDS-max drilling hammers:
allows SDS-plus drill bits to be clamped to SDS-max drilling hammers when drilling with smaller diameters

Recommendation:
Due to the smaller shank diameter of SDS-plus drill bits (10mm) compared to SDS-max drill bits (18mm), it is advisable to preemptively set a lower impact energy on the SDS-max drill hammer (if the hammer allows it).

Recommendation:
Lubricate the shank of the adapter with grease. This will prevent premature wear and prolong the life of the quick-release system in your hammer drill
