ZENESIS™ CORE BIT

Drilling ‚óŹ ZDGUL

The superior ZENESIS™ CORE BITS are made using the same ZENESIS™ pattern diamond technology that made our bridge saw blades #1 in the world. Made for worst case scenario materials like quartzite this bit is the best performing bit we have ever made. The pattern diamond segments guarantee consistency throughout the life of the bit. Brazed diamonds on the outside of the barrel help prevent binding in the hole while brazed diamonds on the inside of the barrel make for easy plug removal.

  • All‐new design for enhanced performance
  • Can be used wet or dry
