Bernardo 4-Jaw Independent Chuck Ø160 mm for Hobby 800 G and Hobby 910 G Metal Lathes

This Bernardo Ø160 mm 4-jaw independent chuck is specifically designed for the Bernardo Hobby 800 G and Hobby 910 G metal lathes. It is the ideal accessory for securely holding irregularly shaped, square, rectangular, off-centre or non-cylindrical workpieces that require precise manual centring.

Unlike a conventional 3-jaw self-centering chuck, each jaw of this chuck can be adjusted independently. This design allows for accurate centring of non-round workpieces and enables eccentric turning operations for specialised machining applications in engineering workshops, maintenance departments and custom part manufacturing.

With a diameter of 160 mm, this chuck offers excellent clamping capacity while maintaining the rigidity required for demanding turning operations. Its robust construction ensures reliable performance and a long service life, even under regular workshop use.

The 4-jaw independent chuck is highly appreciated by machinists, toolmakers and model engineers for its versatility. It allows the machining of previously worked parts, the holding of complex shapes and the production of eccentric components that cannot be achieved using a standard self-centering chuck.

As a genuine Bernardo accessory, it fits perfectly on compatible lathes and significantly expands the machining capabilities of your machine.
