Spiral Point STI Tap: 7/8-9 UNC, 3 Flutes, Plug, High Speed Steel, Oxide Finish MPN:30104101

This Spiral Point tap features 7/8-9 UNC threads and 3 flutes designed for heavy-duty applications with high speed steel construction for enhanced wear resistance against rust or chipping due to continuous use. Applicable for mild and hardened steel alloys alike, it boasts plug design holding the tap straight during initial thread creation; thus preventing slippage while engaging threads on both mating materials with precision. For industries needing robust tapping options that ensure accurate threads like automotive assembly or heavy machinery maintenance sectors where precision and reliability is critical, this tool offers a suitable solution as an affordable alternative for single-use jobs to prevent overstocking of unused taps while meeting ISO & ASME standards.
