Electricians, plumbers or heating and air conditioning installers often need to use this drill bit. PRO SDS plus-5X hammer drill bits are designed for this difficult task and have a robust 4-flute design that will not jam or break when hitting reinforcement.

The masonry drill bit has 4 spiral flutes that channel dust away from the impact point, ensuring effective and long-lasting performance. Suitable for all SDS plus rotary hammers.
