2 inch bit. This is a close-up, eye-level shot of a large, gray core drill bit, angled slightly to the right and positioned against a plain white background. The bit has a wide, cylindrical cutting head with horizontal grooves and sharp teeth, which then narrows to a smooth shaft with a black collar before ending in a rectangular attachment point.
3-1/4 inch bit. This is a close-up, eye-level shot of a large, gray core drill bit, angled slightly to the right against a plain white background. The bit features a wide, cylindrical cutting head with horizontal grooves and sharp teeth, which tapers down to a narrower, smooth shaft with a black collar and a rectangular attachment point at the end.

Punch Flawless Deep Large-Diameter Holes Through Reinforced Concrete and Hard Masonry

Dominate the most grueling jobsite drilling challenges and maximize your coring productivity with the ultra-rugged Diablo SDS-Max Carbide Tipped Core Bits. Purpose-built for commercial electricians, mechanical plumbers, HVAC installers, and structural masons who frequently route conduit, drainage pipes, and large utility lines through dense materials, these premium masonry core saws deliver unmatched performance. Forged as a unified, solid one-piece core bit tool, the entire shaft and cutting head are masterfully stabilized from end to end. This high-integrity layout absorbs the intense structural stress and punishing high-joule pounding forces exerted by heavy-duty corded or high-voltage cordless SDS-Max rotary hammers, preventing the catastrophic fractures and bit snapping commonly experienced with multi-piece modular alternatives.

Engineered for lightning-fast penetration speeds and long-lasting durability, this industrial core bit utilizes a specialized multi-tooth matrix of razor-sharp carbide teeth. These premium cutting edges are uniquely offset and engineered to withstand intense thermal spikes and high-impact friction, maintaining a sharp face while boring smoothly through cured concrete, aggregate block, stone, and brick work. Featuring an advanced Peak Point Tip geometry, the lead center bit forces aggressive, pinpoint-accurate starts that instantly grab the target material and completely eliminate bit walking or surface marring. Paired with a continuous, high-capacity spiral flute outer channel that rapidly lifts abrasive dust away from the cutting zone, this layout keeps the carbide core significantly cooler to minimize drag and deliver clean, round, burr-free utility voids on every single pass.

Key Features

  • Premium Offset Carbide Teeth: Heavy-duty carbide cutting matrix shrugs off punishing friction and excessive operating heat to provide superior tool life over standard cutters.
  • Heavy-Duty One-Piece Core Design: Unified structural engineering strengthens the core bit body from shank to head for ultimate stability and extreme impact resistance.
  • High-Velocity Spiral Dust Flutes: Deeply ground helical flutes quickly lift and extract pulverized masonry dust out of the boring channel to preserve cutting edge cooler.
  • Aggressive Peak Point Lead Tip: Specialized center pilot geometry creates immediate bit engagement and eliminates surface wandering for perfectly centered layout holes.
  • SDS-Max Drive Tool Compatibility: Standardized industrial SDS-Max shank provides an unyielding, non-slip positive lock inside commercial rotary hammers.
  • Optimized Cordless Energy Draw: Low-friction cutting geometry reduces tool drag to maximize holes per charge on high-output cordless battery systems.

Pro-Tip: When using large-diameter one-piece SDS-Max masonry core bits, never force or lean your full body weight into the rotary hammer to hurry the cut. Let the tool's internal hammering mechanism work at its own natural cadence. Keep the bit perfectly square to the concrete face to prevent binding, and occasionally back the bit out slightly while drilling to facilitate the removal of packed dust. If you encounter heavy steel rebar hidden inside the concrete matrix, drop your rotary tool speed immediately to minimize excessive thermal build-up on the carbide tips until you pass completely through the reinforcement metal.
