Drillco 3/4-16 HSS Bottoming Tap (20A148FB)
Drillco 20A148FB 3/4-16 HSS Bottoming Tap is engineered for precise and clean threading in blind holes. As part of the Straight Flute “Hand Taps” line, this bottoming tap features a minimal chamfer of 1–2 threads, allowing threads to be cut close to the bottom of a hole. Made from high-speed steel (HSS), it provides durability and consistent cutting performance. A 118° conventional point aids rapid penetration, while the black oxide coating enhances tool life and chip evacuation. The jobber length design makes it suitable for a variety of setups. Proudly made in the USA.
