Engineered for precision through-hole tapping, the OSG Metric Spiral Point Threading Tap delivers consistent M22 x 2.5 threads with durability and efficiency. It's ideal for professional machinists and high-volume workshops seeking repeatable, reliable threading results.

• Size and thread: M22 x 2.5 through-hole metric spiral point threading tap for accurate internal threads in metal components.
• Material: HSS-E (high-speed steel with cobalt) for superior hardness, wear resistance, and heat tolerance during cutting.
• Coating: Steam oxide coating enhances lubricity and protection against heat, contributing to longer tool life and smoother operation.
• Cutting geometry: Spiral point design facilitates fast chip evacuation and cleaner thread formation in through-holes.
• Application: Specifically optimized for through-hole tapping tasks, delivering consistent thread depth and profile across multiple parts.

With its cobalt-infused HSS and steam oxide finish, this tap maintains a sharp cutting edge under demanding conditions, reducing wear and extending service life. The spiral point geometry moves chips out of the hole quickly, minimizing clogging and improving surface finish on the internal threads. Designed for through-hole work, it supports reliable alignment and repeatable results in metal fabrication, automotive, and machinery assembly projects. For shops seeking durable, high-performance threading tools, the OSG Metric Spiral Point Threading Tap offers a precise, efficient solution that keeps pace with daily manufacturing demands.
