The Lackmond PRM Series Wet Concrete Core Bits combine value and increased performance. They are used on reinforced concrete with aggregate of soft to medium hardness. These bits are engineered with a segmented diamond rim and slightly harder bond for extended bit life in more abrasive materials. Excellent for medium steel and rebar. More diamonds at a higher quality giving you longer lasting bits that cut faster, reducing your cost per hole.
Use wet only. Sizes 1" to 14".
Core Travel: 14"
PRM bits below 1 3/4" are equipped with 5/8"-11 threads. Bits 1 3/4" and above are equipped with 1 1/4"-7 threads.
