Drillco 1/4-18 Interrupted Thread (293A116)
Drillco 293A116 1/4-18 Interrupted Thread Tap is specifically designed for creating precise interrupted pipe threads, which provide improved thread engagement and better sealing in critical piping applications. The nominal size corresponds to the pipe fitting size rather than the actual tap diameter, ensuring compatibility with standardized pipe fittings. Made from premium grade high-speed steel (HSS), this tap offers excellent durability and long service life. Featuring plug geometry and a bright finish, it delivers enhanced lubricity for smoother cutting and increased wear resistance. The spiral point efficiently ejects chips through the bottom of the hole, reducing clogging and improving tapping performance. This tap is compatible with both tap wrenches and reversible power tools and includes a square shank for use with standard-sized tap wrenches. Proudly made in the USA, it provides reliable precision and quality for demanding professional use.
