Holds up to 1.5 times longer than a Bosch SDS plus-1 drill bit. Reinforced concrete is a common material in infrastructure, commercial, and residential construction. Electricians, plumbers, or heating and air conditioning installers often need to rely on this drill bit. The PRO SDS plus-5X hammer drill bits are designed for this challenging task and feature a robust 4-cutter design that neither jams nor breaks upon contact with rebar. The 4-cutter head of the PRO SDS plus-5X has an embedded cross made of high-quality tungsten carbide, providing comfort for professionals who need to drill precise holes in reinforced concrete. The masonry drill bit has 4 spiral flutes that direct dust away from the impact point, ensuring effective and long-lasting performance. Compatible with all SDS plus rotary hammers.
