Snappy Tools 3/32 in. Countersink and Bit makes drilling pilot holes and countersinking or counterboring for screws a seamless, one-step process. Designed with an 82° countersink angle that matches the head of most screws, this tool ensures precision and efficiency. Crafted in the USA with tight tolerances, it is made from thru-hardened alloy steel for long-lasting cutting performance. The 1/4" hex power bit shank fits easily into impact drivers and quick-change chucks. The pilot drill bit can be easily adjusted or replaced by loosening the hardened set screw, which s a secure hold. For even more precise depth control, the Snappy Premium Rotating Depth Stop (Part # 43032) is available separately.
