The OSG UNC Spiral Point Threading Tap is a high-performance tool designed for through-hole threading in demanding machining tasks. Crafted from HSS-E (high-speed steel with cobalt) and finished with a Steam Oxide coating, it delivers precise threads with extended tool life.

• Threading type: UNC spiral point design that promotes efficient chip evacuation and reliable starts in through-holes.
• Material: HSS-E for enhanced hot hardness and wear resistance in tougher metals.
• Coating: Steam oxide reduces friction, improves wear resistance, and helps extend service life in demanding environments.
• Size and application: UNC threading for through-hole work, specifically suited to the 1-8 through-hole tap size as listed.
• Through-hole performance: Optimized for clean, consistent thread formation in through-holes, reducing the need for rework.

Engineered for reliability in production and repair settings, this tap delivers consistent thread quality, improved heat resistance, and longer tool life. The spiral point pushes chips forward and away from the cut, minimizing clogging and allowing for smoother, faster tapping in through-holes. Ideal for shops that demand durable tooling for critical components and high-throughput machining tasks.
