Product Category Description & Specifications

Installing masonry screws is easy when you use our extra long masonry bits! Precision ground carbide tips ensure that an oversize hole doesn’t reduce holding power. The 5/32", 3/16", and 15/64" bits fit tool holders designed for concrete anchor bits, and standard drill chucks; the 7/32" bits (for 1/4" screws in extra-hard masonry) only fit drill chucks designed for use with rotary hammer drills, and will not perform to satisfaction with standard drills.
