• Best For: Crews wet coring 10-inch holes in concrete and masonry who want the MK Black Supreme line rather than the standard-grade MK Yellow.
• Highlight: The 156348 is the 10-inch MK Black Supreme bit, sitting between the 9-inch 170051 and the 12-inch 204011 in that line.
• Expert Note: Match the bit's thread to your coring rig before ordering, since core bit threads vary across MK's range.
