Just used my new Marcrist DDM1 and PC850 cores, they're rather brilliant - 1 course of breeze took 15 secs, a course of engineering brick took about 75 secs. It wasn't out of its box more than 5 mins. Highly recommended. Used to use Bosch 4kg SDS hammer stop & Edge diamond cores, they took ages - Not anymore.
