Description

The OSG UNC Spiral Point Threading Tap is engineered for professionals who demand quick, precise through-hole threading with durable, long-lasting performance. Crafted from cobalt-enhanced high-speed steel (HSS‑E) and finished with Steam Oxide coating, it delivers reliable cutting power for No. 10 x 24 UNC threads.

  • Design: Spiral Point geometry that efficiently pushes chips ahead, ideal for through-hole tapping.
  • Material: HSS‑E (high-speed steel with cobalt) for superior hardness and wear resistance during high-speed cutting.
  • Coating: Steam Oxide finish to reduce friction, improve heat tolerance, and provide added corrosion protection.
  • Thread: Through-hole UNC thread profile No. 10 x 24, suitable for standard fastener applications.
  • Application: Specifically suited for through-hole metal work, including fixtures and assemblies where clean, accurate threads are essential.
  • Durability: Designed to extend tool life in demanding machining environments, helping reduce downtime and tool changes.

This combination of material, coating, and spiral-point design translates to faster cutting with efficient chip evacuation, tighter tolerances, and consistent thread quality across multiple holes. For projects using No. 10 fasteners, this OSG tap offers dependable performance, repeatable results, and reduced rework in everyday metalworking tasks.
