The OSG UNC A-Spiral Point Threading Tap is a precision tool designed for through-hole UNC threading, built to deliver fast, clean threads with long wear life. It’s ideal for shops and machinists who need reliable performance across a variety of materials.

• Size and thread: 3/4" diameter, 10 TPI UNC, right-hand thread for through-hole applications
• Material: Powder metal substrate for enhanced durability and wear resistance
• Coating: TiCN coating improves heat resistance, extending tool life and maintaining performance
• Chip evacuation: Spiral Point geometry enables efficient chip removal and reduced tapping time
• DIN standard: DIN 2184-1 compliant for compatibility with common holders and taps
• Through-hole optimization: Specifically configured to deliver reliable threads in through-hole work

The combination of a spiral point, TiCN coating, and powder metal construction translates into higher cutting speeds, a smoother finish, and more consistent threading results across materials. This tap is built to withstand production environments, delivering repeatable performance from job to job while simplifying setup with DIN 2184-1 compatibility. Use it for through-hole UNC threads where fast, clean, and dependable results matter, from light fabrication to more demanding machining tasks.
