Diamond Core Drill Bit 1-1/4 In, 14 In Depth, 5/8-11

Diamond wet core drill bit delivers cleaner, more precise holes in concrete by using water cooling to reduce dust and heat buildup. Built with a diamond-grit cutting head and carbon steel body, it’s designed for steady wet coring with less wandering thanks to regular teeth and a concentric shaft. The universal 5/8"-11 inner thread fits many core drilling setups and handheld drills, making it a practical choice for installers working on masonry, brick, and block.

When you need reliable wet coring for HVAC openings, pipe and conduit runs, railing posts, or general construction work, this bit is built to stay stable under load and keep cutting efficiently. Laser welding helps secure the cutting segments to reduce the risk of tooth loss during demanding drilling, while the 14" max core depth supports thicker walls and slabs. Keep water flow steady for cooling and debris control, then get back to clean installs with less cleanup. Grab yours today.
