Hillman 5/32 in. x 4-1/2 in. Carbide Bit

Carbide drill bits have a carbide tip that ensures the precise drilling of pilot holes. A concrete screw is designed and manufactured so the threads of the screw will tap threads into concrete, brick or block. The threads are hardened without making the body of the screw so brittle that the screw would shear off. For best results, use a hammer drill to install.
