This bit is ideal for drilling holes in concrete, block, and brick where the depth of the hole exceeds the depth of a standard core bit.

The B-66313 features a solid tungsten carbide head, a carbide-tipped centering point for more accurate drilling, and a solid one piece system that transfers power directly to the end of the bit.

A two flute design provides faster clearance of debris.
