Description
Drillco 25A340P 2-5/8-8 HSS Plug Tap is designed for heavy-duty threading applications commonly found in the oil field, gas exploration, and power generation industries. This 8-pitch plug tap is suitable for larger diameters up to 4″ and features a plug geometry that balances ease of thread starting with efficient chip evacuation. Made from premium grade high-speed steel (HSS) with a black oxide surface treatment, it ensures extended tool life and enhanced wear resistance. The spiral point design helps eject chips through the bottom of the hole, reducing clogging. Additionally, a reduced neck provides better clearance when tapping deeper holes. The tap includes a standard square shank for compatibility with tap wrenches and powered machines. Proudly manufactured in the USA for consistent quality and performance.
