Premier Diamond Products dry cores need an adaptor to "drive" them from any machine that features a slipping clutch and/or rotary hammer stop.

Here we have the three main core adaptors.

DC11020 : is for dedicated diamond core drills which feature a 1/2" capacity 3 jaw chuck and a safety clutch as standard.

DC11040 : is designed to fit to any SDS+ machine which has a built in safety clutch and must also feature rotary hammer stop. Diamond cores are NOT to be used in conjunction with hammer action.

DC11045 : is designed to fit to any SDS MAX machine which has a built in safety clutch and must also feature rotary hammer stop. Diamond cores are NOT to be used in conjunction with hammer action.
