A 1 3/8 inch core bit with an 8 mm segment height is designed with an offset style segment. This provides segment and weld protection on the core bit. The Zenesis Black Core Bit has brazed diamonds inside the barrel to easily remove the plug after drilling. The outside of the barrel utilizes the diamond abrasion to prevent binding on the material. In addition, it offers felixibility of use with its wet and dry core drilling methods.

The abrasion on the barrel is reinforced with high-grade diamond powder. The arrangement of the diamonds on Zenesis diamond tools use a patented technology. An ideal amount of diamonds are exposed for consistent cuts and a longer life of the tool. This pattern is speedier than other core bits in the market and has a stronger durability. Zenesis Black Core Bit optimizes the concentration and distribution of diamonds of every core bit during manufacturing.
