• Highlight: MK Diamond's Zenesis core bit uses a multi-layered diamond matrix designed for fast, clean coring in cured concrete with medium aggregate.
• Best For: Plumbers, electricians, and concrete contractors drilling clean 2-1/4 inch pass-throughs for conduit, anchors, and pipe.
• Expert Note: The 57mm wet/dry diamond segments hold cutting speed across abrasive aggregate, so a single Zenesis bit stays productive through repeated holes in a slab.
