• Best For: Contractors coring 3 inch drain and vent stack penetrations through concrete or asphalt with light to moderate rebar.
• Highlight: The MK Orange line high diamond concentration keeps a 3 inch hole cutting fast through light rebar without stalling the drill.
• Expert Note: Use a rig-mounted drill for stability on this 3 inch bit; upgrade to MK Black Supreme when reinforcement runs moderate to high.
