The OSG UNF Spiral Flute Threading Tap in 3/4 x 16 UNF is engineered for precise, reliable blind-hole threading in metalworking tasks. Crafted from HSS-E (high-speed steel with cobalt) and finished with a Steam Oxide coating, it combines durability with steady performance in demanding conditions.
- Size and thread: 3/4-16 UNF threading tap designed for fine, high-precision threads in blind holes
- Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance
- Coating: Steam oxide coating reduces friction and extends tool life in tough materials
- Flute design: Spiral flute geometry optimizes chip evacuation, minimizing clogging in blind-hole tapping
- Application: Specifically suited for blind-hole threading where access is limited and precision matters
With its cobalt-enhanced core and steam-oxide finish, this tap maintains sharpness longer, handles heat more effectively, and delivers clean, accurate threads. The spiral flute design lowers the risk of chip buildup and breakage in deep, hard-to-reach pockets, helping you complete critical machining tasks with confidence and efficiency. This tap is a dependable choice for operators who demand consistent thread quality and extended tool life in demanding metalworking environments.
