1/2 In. Carbide Tipped SDS-Plus Hammer Stop Bit SDS-Plus Shank 1 Pk

The Diablo DMAST1020 is a carbide-tipped hammer drill stop bit engineered for drilling in concrete and masonry. Designed for use with SDS-Plus rotary hammers—whether corded or cordless—this bit is built with a stop collar that provides a pre-determined stopping point, making it ideal for shallow anchor installations and repetitive work where depth consistency is required.

The dual-cutter, carbide-tipped design delivers fast, clean cuts in masonry materials. By pairing a unique brazing and hardening process with carbide tips, this bit extends working life compared to standard bits and maintains performance across both corded and cordless SDS-Plus rotary hammers. The built-in stop collar enables repeatable depth control for efficient, accurate hole placement on every job.
