Two more mobsters yesterday pleaded guilty to what prosecutors called a “staggering” crime spree that included viciously beating deadbeat gamblers.

Reputed Gambino crime-family soldier Thomas Orefice and alleged right-hand man Dominick Difiore face nine or more years in prison under terms of their deals with the feds.

The pleas close the book on last year’s Gambino crackdown. Twelve other wiseguys, including mob boss Daniel Marino, have pleaded guilty to authorizing a 1998 hit on Marino’s nephew Frank Hydell for becoming a snitch.
