The OSG UNF Spiral Point Threading Tap is a precision through-hole tapping solution built for machinists who demand consistent, high-quality UNF threads. Crafted from cobalt-enhanced HSS-E and finished with a durable steam oxide coating, it delivers reliable performance in demanding applications.

• Thread Type: UNF Spiral Point design engineered for efficient chip evacuation and smooth entry in through-hole work.
• Material: HSS-E (high-speed steel with cobalt) for improved hardness, heat resistance, and extended tool life.
• Coating: Steam oxide finish provides added lubricity and wear resistance in tough cutting conditions.
• Size: Through-hole friendly 1 x 12 UNF size, optimized for precise threading in through holes.
• Application: Specifically configured for through-hole threading, delivering consistent thread formation across passes.

This tap supports precise, high-quality threads with extended tool life. The spiral point geometry combined with a cobalt-enhanced core and oxide coating helps maintain accuracy, manage heat, and reduce downtime in critical machining tasks.
