• Best For: Contractors coring a 2-1/4 inch hole in concrete or asphalt on a wet coring rig; choose part 156382 when 2-1/4 inch is the hole diameter you need.
• Highlight: Segmented MK Black Supreme wet bit sized at 2-1/4 inch (part 156382); the diameter is what separates it from the other bits in the same range.
• Expert Note: Diameter and thread vary across the MK Black wet range, so match the 2-1/4 inch size and your rig's thread before ordering part 156382, or contact us to confirm the fit.
