 GP SERIES  - CONCRETE MILLING CUTTER
Used in a drill rig, the B & A Concrete Milling Cutter will provide a clean hole in all types of concrete. Used wet with a small amount of water or completely dry. The Concrete Milling Cutter is a viable alternative to fragile diamond drills as it will withstand rough usage and can be completely rebuilt. Rebar and wire mesh that are embedded in the concrete being drilled are not a problem for the B & A Concrete Milling Cutter. Note: All diameters are nominal, exact tolerances upon request.

When are Carbide-Tipped Core Drill Bits the best alternative to Diamond Core Drill Bits for a particular application?

In general when evaluating the advantages of using core drill bits carbide or diamond drill bits, consider the 80/20 rule. 80% of applications are suitable for wet diamond core drill and may not be significantly improved by utilizing carbide core drill bits. 20% of applications, require other alternative solutions and B&A WET/DRY CARBIDE-TIPPED CORE DRILL BITS offer significant advantages in such applications.

What are these applications?

When encountering applications requiring core drill bits to drill through multiple layers of materials stacked together, such as wood, steel, concrete, rebar and a host of others material combinations, diamond drill bits performance can be hindered or completely prohibited. The Best & Available alternative is the B&A WET/DRY CARBIDE-TIPPED CORE DRILL BITS, which are designed to solve these difficult jobs encountered by the drilling professional.

Can Carbide Core Drill Bits and Diamond Core Drill Bits work together?

Yes, professional core drillers in a variety of situations effectively use both Diamond Drill Bits and Carbide Core Drill Bits to complete a project. Whether starting a hole, completing a hole, or anywhere in between, carbide core drill bits and diamond core drill bits both make significant contributions. Example: starting a hole into concrete only to encounter plate steel an inch into the hole. Switch to carbide core drill bits, drill through the steel, then switch back to the diamond drill bits until the next hindrance to the diamond bit is encountered.
