Zenesis line of Black Core Bits offer an enhanced performance specially designed for hard materials like engineered stone and granite. It comes in 2 1/2 inch diameter and 8 mm segment height. Its barrel is coated with brazed diamonds inside for easy removal of the plug after drilling. Outside the barrel the diamond abrasion serves as a way to prevent binding of the bit in the material. The segments are made in an offset style to provide segment and weld protection. All these features make the Black Core Bit durable and versatile.
