You cannot saw a hole with the hole saw alone! What is missing now is a smart shaft. The PAROLI® "PUMPSHANK®" ejector shank has a stable shank with a hexagon on one side for safe attachment to the machine chuck. On the other side we have attached a very special conical external thread. What is that for? This precision thread is designed in such a way that it releases an adapter with the same internal thread in less than one turn. Screw the adapter onto a hole saw using the two screws provided and now lock this hole saw onto the ejector shaft with less than one turn. Yes, you can also call this a quick-change adapter.
Features:
- compatible with almost all commercially available hole saws
- precise application with safety push handle
- perfect concentricity due to adapter with conical thread
- instantaneous ejection of the saw core using the safety push handle
- not twisted in the machine chuck thanks to the hexagonal shank
