Frequently Asked Questions

The 12 mm collet chuck — what tools is it used for on the UWS 300/350?

The 12 mm collet chuck accepts tools with an exactly 12 mm shank: end mills with a 12 mm shank, drill bits with a reduced 12 mm shank, reamers, and taps to be sharpened. The collet chuck ensures superior concentricity compared to the standard self-centering chuck — essential for sharpening where a centering error of 0.1 mm results in an asymmetrical cutting edge. Customer support in Italian available.

Is this chuck interchangeable with collet chucks from other manufacturers?

The UWS Bernardo series chucks have a specific machine attachment — not interchangeable with generic ER chucks or collets from other manufacturers. Only purchase original Bernardo sizes compatible with your UWS 300 or UWS 350. Customer support in Italian available.
