The Dewalt Extreme 10 Piece SDS Plus Masonry Drill Bit Set offers professional contractors a versatile selection of drill bits for demanding concrete and masonry applications, all stored in a robust, modular Tough Case. Each of the ten included SDS Plus Extreme 2 bits features a 2-Stage Helix designed to accelerate the removal of debris from the tip during drilling. This reduces working temperature and speeds up drilling performance across a range of hole diameters, making the set well suited to fixing mechanical anchors, drilling service penetrations, and general concrete work on site. The bits incorporate a ToughCore tapered central core for improved stability and reduced risk of breakage under load. A clearly visible Wear Mark allows contractors to confirm that holes are drilled to the correct diameter — particularly useful when installing mechanical anchors to Specifications: The set is supplied in a medium Tough Case with a clear lid for quick bit identification. The inner dovetail system allows bit bars to be repositioned to suit your preference, and the case connects and stacks securely with other small, medium, and large Tough Cases using the integrated locking system.
