Learn more about Klarna
Description
Engineered for precision through-hole threading, the OSG UNF Spiral Point Threading Tap No. 0 x 80 delivers clean, accurate UNF threads with dependable durability. Built for machinists and job shops demanding repeatable results, it combines high-speed steel with cobalt (HSS-E) and a Steam Oxide finish for lasting performance.
- UNF Spiral Point geometry: Optimized for through-hole tapping with efficient chip evacuation, reducing build-up and improving thread quality.
- Material: HSS-E (high-speed steel with cobalt) for increased hardness, wear resistance, and heat tolerance during demanding taps.
- Coating: Steam Oxide coating provides a low-friction, durable surface that enhances tool life and lubricity in repetitive cuts.
- Size: No. 0 x 80 UNF threading specification, suited for small-diameter through-holes and fine-pitch applications.
- Through-Hole Suitability: Specifically designed for through-hole threads, promoting accurate alignment and consistent results across runs.
- Durability & Longevity: Combination of HSS-E and steam oxide coating supports extended tool life under high-speed tapping conditions.
This tap is ideal for precision assemblies where small UNF threads are required, such as miniature mechanical components, electronics housings, and tight-fitting fasteners. The spiral point aids rapid chip clearance, enabling smoother cuts and fewer reworks, while the cobalt-enhanced substrate helps maintain sharpness over multiple uses. For shops focusing on accuracy, efficiency, and durable performance in through-hole threading, this No. 0 x 80 UNF tap from OSG delivers reliable results.
