Snappy Tools 1/8 in. Countersink and Bit makes drilling pilot holes and countersinking or counterboring for screws a simple, efficient process. Designed with an 82° countersink angle that matches most screw heads, this tool ensures a fit every time. Precision machined in the USA with tight tolerances, it is crafted from thru-hardened alloy steel for long-lasting cutting performance. The 1/4" hex power bit shank fits impacts and quick-change chucks, providing versatility and convenience. Adjusting or replacing the drill bit is easy—simply loosen the hardened set screw for a secure hold on the pilot drill. For even more precise depth control, the Snappy Premium Rotating Depth Stop (Part # 43032) is available separately. Model Number:
