Product Overview
Product Overview
The OMMDR22 is an automatic chuck tapping machine, made in Italy by SerrMac International, a manufacturer with over 75 years of precision machine-tool experience since 1950. It steps the MDR line up to M22 threads for heavier fastener and component work without giving up production speed.
A lead-screw chuck ("patrona") provides true rigid tapping, and the mechanical variator delivers continuous speed adjustment across the full range. Automatic tapping cycles keep large batches moving with repeatable thread quality and minimal operator input.
Offered in column or pedestal configuration and supplied with one chuck of your choice, the MDR22 suits production environments that need dependable, precise tapping on larger threads.
