• Highlight: The EDCO M-1 Series core drill comes complete and bores clean 14-inch-capacity holes through concrete for plumbing, electrical, and HVAC penetrations.
• Best For: Contractors cutting precise round openings for pipe, conduit, and duct where a saw can't make a clean bore.
• Expert Note: Anchor or vacuum-base the rig before drilling; a stable M-1 mast keeps the bit true and protects the core bit's segments.
