This is a high quality core drill bit for drilling up to 14" deep in reinforced concrete, cured concrete, green concrete, asphalt over concrete, masonry, stone, brick and block, and stucco.
Each segment on this core drill bit has lots of large diamonds you can see with naked eyes. This is one of the reasons why you will be getting a lot of holes out of them. Use our heavy duty core drill bit instead of renting them or hiring out a professional driller this way you will save big on your cost per hole.
All core drill bits under 2" are 5/8"-11 threaded while those that are 2" and above are 1 1/4"-7 threaded which is the industry standard.
