NQ3 Impregnated Diamond Concrete Core Drill Bits - 9mm/12mm/16mm Crown Height Options for High-Speed Drilling
Professional impregnated diamond core drill bits engineered for high-speed drilling in reinforced concrete, dams, tunnels, and bridge construction applications.
Impregnated diamond core bits feature high-quality synthetic diamonds evenly distributed through a metal alloy matrix. The matrix erodes at the same rate as diamond wear, continuously exposing fresh cutting surfaces for optimal performance.
