SDS Plus Drill Bit Set 17Pcs 110 160 200 250mm for Electric Hammer Concrete Wall Brick Block Masonry Drilling

This 17-piece SDS Plus set covers the essential range (110-250mm) for most residential concrete and masonry work. The bits feature hardened carbide tips that perform adequately on standard brick and block, though they lack the premium tungsten carbide composition of professional-grade alternatives. Chuck compatibility is reliable with standard SDS Plus rotary hammers, and the four length options provide versatility for different wall depths. The set delivers solid value for homeowners tackling occasional drilling projects, but the bits show wear faster under sustained commercial use—expect 40-60 holes per bit in reinforced concrete before noticeable dulling. Bit retention and runout are acceptable for DIY applications, though precision isn't competition-grade.
