Frequently Asked Questions
The 8 mm collet chuck — what tools is it used for on the UWS 300/350?
The 8 mm collet chuck accepts tools with an exactly 8 mm shank: end mills with an 8 mm shank, drill bits with an 8 mm reduced shank, reamers, and taps for sharpening. The collet chuck guarantees superior concentricity compared to the standard self-centring chuck — essential for grinding where a centring error of 0.1 mm results in an asymmetrical cutting edge. Customer service available in Italian.
Is this chuck interchangeable with collet chucks from other manufacturers?
The UWS Bernardo series chucks have a specific machine connection — 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 service available in Italian.
