COLLETS

COLLETS 

Serinex is specialized in the production of clamping collets for every kind of tool. Our production stretches from collets for tools machines (for steel working, aluminium working and even wood and plastic working), to elastic collets for adaptors and collets for electric tools, in every size. For our clamping collets we only use high qualified steel, coming from qualified steelworks; furthermore every lot of material is provided with a quality certificate which guarantees its goodness and its peculiar characteristics.

Every working is performed in our modern productive department in Annone di Brianza, not far from Lecco. we only use the latest generation CNC machines to produce elastic collets for adaptors; Furthermore, every phase in the production of tools machines collets is carefully controlled by our technicians, following the legislative procedures contained in the certification ISO 9001: 2015, and verified by our thirty-years experience. All the elastic collets for adaptors can be provided in three classes of precision: Standard, Ultraprecision, Megaprecision.

The entire production of clamping collets undergoes a finishing touch called “Extra-fine”, which allows to obtain a superficial “super-finishing touch”. We are able to realize special collets or collets constructed on specific indications of the customer, and thanks to our technical office we can give professional advice for the production of special collets. In our automatic warehouse every kind of collet is always available in every size on the market.
