Drillco 1-3/8-12 HSS Left Hand Bottom Tap (23A224FB)
Drillco 23A224FB 1-3/8-12 HSS Left Hand Bottom Tap is a precision-engineered hand tap designed to create durable left-hand (counterclockwise) threads with a bottoming tap geometry, ideal for threading close to the bottom of blind holes. Constructed from premium-grade High-Speed Steel (HSS) and finished with a black oxide coating, this tap offers enhanced wear resistance and longer tool life. The bottoming design allows for maximum thread depth and clean thread formation, while the standard square shank ensures compatibility with most tap wrenches. This tap is ideal for applications where left-hand threads are necessary to prevent fastener loosening due to rotational forces. Proudly made in the USA for superior quality and reliability.
