Greenlee MAS-5/16 Masonry Drill Bit, 5/16-Inch
The new Quick Carbide Tip Change Masonry Bits have a one-piece hardened carbon steel body and hex shank to provide a stronger bit that will not disassemble when drilling in deep or tough materials. They are hammer drill rated with a carbide grade tip for faster penetration, easier drilling, and longer bit life. In addition, the new Quick Carbide Tip Change Masonry Bits have a 1/4-inch quick-change hex so they can be used in quick-change chucks, conventional adjustable drill chucks, and hex adapters for more versatility.
