Meet the OSG Metric Spiral Point Threading Tap in M20 x 2.5—engineered for precision through-hole tapping in professional metalworking. Crafted from HSS-E (high-speed steel with cobalt) and finished with a steam oxide coating, this tap blends toughness, heat resistance, and long tool life for demanding machining environments.

• Brand and type: OSG Metric Spiral Point Threading Tap designed for through-hole threading
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance
• Coating: Steam oxide coating to reduce friction and improve corrosion resistance
• Size: M20 x 2.5, suitable for standard through-hole applications
• Design: Spiral point geometry promotes fast chip evacuation and clean thread formation in through-hole work
• Application: Optimized for metalworking tasks in steel, cast iron, and compatible alloys in production or shop settings

This threading tap delivers reliable, consistent performance when producing through-hole threads. The cobalt-infused HSS-E core maintains cutting edges under higher temperatures, while the steam oxide coating lowers friction, reduces wear, and extends tool life. The spiral point design helps push chips ahead of the tap, minimizing clogging and ensuring smoother starts and steadier thread profiles. Ideal for machinists and shops that demand durability, precision, and repeatable results across batch runs.
