Why do you need a Grabber Standard Corebits?
Engineered for Reinforced Concrete, Brick & Heavy Utility Penetrations
If you are drilling smooth penetrations through tough jobsite materials, selecting high-performance core drill bits is essential for fast penetration rates and low cost-per-hole. Standard masonry bits quickly dull or snap when striking rebar. Grabber Power supplies industrial wet and dry core drill bits engineered with high-density diamond segments to slice through heavy steel reinforcement, high-PSI cured concrete, brick, block, and natural stone.
We partner directly with top-tier equipment manufacturers—including Husqvarna Construction and Core Cut / Diamond Products—to deliver every wet and dry core drill bits spec in our inventory. Built with laser-welded diamond segments, durable steel barrels, and standard 1-1/4″-7 threaded arbors, our diamond core drill bits maintain concentricity and prevent binding under heavy drilling loads.
Whether your crew is drilling utility lines, plumbing runs, electrical conduits, or structural core samples, Grabber stocks standard diameters from 1 inch to 14 inches alongside custom tube lengths. Check out our main Blades and Bits category page for matching core drill rigs and floor saw blades.
STANDARD COREBITS
Professional Standard Diamond Core Bits Engineered for accuracy and efficiency, our professional-grade core bits are designed to deliver clean, precise holes in a wide range of materials, including reinforced concrete, stone, and masonry. Whether you are installing HVAC, plumbing, or electrical conduits, our core bits offer the consistent drilling speed and longevity that professional contractors rely on to meet project deadlines. With a focus on durability and segment retention, these bits are built to withstand the rigors of heavy-duty drilling applications.
