1" Crowned Diamond Core Drill For Hard Material

This 1” diamond core drill bit is 14” in length and has a 5/8” threaded arbor.

The soft bond diamond core drill bits are the best choice for drilling through stone and other hard material such as cured concrete with hard local aggregate. Usually the concrete you will be drilling is made locally quarried stone. Depending on were in the country you’re located you might have either harder or softer stone mixed in the concrete. If you have problems with the bit dulling, glazing or segment loss the bit might have a hard or medium hard bond. A soft bond diamond core bit allows the matrix to wear faster and release the diamond edged which does the cutting. Soft bond diamond core bits will effectively core added hard aggregate such as river rock, granite and quartz. If you have any questions please call 1-866-647-8665
