Sold as a set of three so you're covered regardless of what you're drilling into. Combined they will cover almost any need when working with a wide range of materials. The unit's design keeps bits safely stored and readily accessible by simply rotating the clear cap. You'll receive three containers in an order, one container for masonry ( stone or concrete), one brad point (for wood), and one set of HSS high-speed steel (metals and other hard materials), with 11 bits contained in each set (33 total bits). The HSS steel bits offer a combination of hardness, wear resistance, and high-temperature tolerance. The bit sizes range as follows: masonry 7/64'' 7/16''; brad point 7/64'' 3/8''; and high speed 1/16'' 5/16''. Our Exceptionally Useful Drill Bit Organizer really lives up to its name.
