Description
The OSG Threading Tap - UNF Spiral Point HSS-E - Steam Oxide Coated - Through Hole - 9/16 x 18 is built for precise through-hole threading in demanding production environments. Crafted from cobalt-enhanced HSS-E and finished with a steam oxide coating, this tap delivers durable performance and consistent thread quality.
- Size and Thread Type: 9/16"-18 UNF spiral-point threading tap designed for through-hole applications, providing fast, clean starts and accurate threads.
- Material and Coating: HSS-E (high-speed steel with cobalt) with a steam oxide coating to improve heat resistance and tool life.
- Spiral-Point Geometry: Spiral-point design pushes chips ahead of the tap, reducing clogging and enabling efficient tapping in through-holes.
- Through-Hole Optimization: Specifically engineered for through-hole workpieces, ensuring reliable thread formation without risk of misalignment.
- Durability and Longevity: Robust core with wear-resistant coating supports high-volume use and longer service life in production settings.
- OSG Quality and Technology: Built on OSG’s advanced threading technology for consistent thread profiles and repeatable results across jobs.
This UNF spiral-point tap delivers precise, high-quality threads with minimal runout, supporting tight tolerances in critical components. The cobalt-enriched HSS-E core maintains sharpness at higher cutting speeds, while the steam oxide coating reduces wear and corrosion, extending tool life between regrinds. Its spiral-point geometry makes it well-suited for through-hole applications where chips must be evacuated quickly, improving cycle times and reducing tool sticking. Ideal for production environments including automotive assemblies, precision machined parts, hydraulic components, and general metal fabrication, this tap helps you achieve reliable threads consistently and with less downtime.
