Our Premium Core Bit line is just what the name implies; a premium bit with premium quality industrial diamond concentration. The Premium line of core bits require a water supply for operation. The water aids in removing the slurry and cooling the blade during coring. The coring depth is 14”. We also offer the option of a 6” bit extension. The Premium core bit line is designed with a 7.5mm general purpose segment which combines both accuracy and speed of cut when drilling concrete, block, masonry, natural stone and hardscape aggregates.
