• Best For: Concrete drillers who need a 2-inch (51mm) core and expect heavy steel reinforcement in the cut.
• Highlight: High diamond concentration and a turbo segment design channel slurry better and reduce vibration at 2-inch; in the MK-Blue Turbo line this size is the smallest bit, just below the 2-1/2-inch bit.
• Expert Note: Drilling depth is 14 inches on the 1-1/4-7 nut; longer reach needs an MK core bit extension ordered together with the bit, and the 2-inch (51mm) size is part number 156570.
