The OSG Metric Spiral Point Threading Tap is engineered for reliable through-hole tapping, delivering clean, precise M10 x 1.5 threads with lasting performance for professional machinists and shops.

• Size and Thread: M10 x 1.5 metric spiral point threading tap designed for through-hole tapping.
• Material: HSS-E (high-speed steel with cobalt) for superior toughness and heat resistance in demanding metals.
• Finish: Steam Oxide Coated Plus offers reduced friction and enhanced wear resistance to extend tool life.
• Geometric Design: Spiral point geometry promotes efficient chip evacuation and stable cutting in through-holes.
• Applications: Ideal for through-hole threading in steel, cast iron, and select non-ferrous materials where accurate, high-quality threads are essential.

With its combination of hardened HSS-E core and a durable Steam Oxide finish, this tap maintains consistent performance under high-speed tapping and heavy chip loads. The spiral point design minimizes chip buildup and re-cutting, helping you achieve smooth, reproducible threads in fewer passes. Built for reliability, it’s a practical choice for mills and drilling centers that demand precise threads and longer tool life in through-hole applications.
