Engineered for those who require reliability and performance, the 5/8 in. x 12 in. SDS-plus Quad-Head Shank Drill Bit by Simpson Strong-Tie is a formidable tool for tackling tough materials. Its innovative 4 x 90 head geometry is designed to effectively crush through rebar, preventing stickiness during drilling, which is crucial when working with reinforced concrete. The drill bit benefits from advanced heat-treatment and a shot-peened finish that enhances surface hardness and durability, helping to maintain drilling speed while minimizing wear and resisting bending forces.
