OSG Threading Tap - UNC Spiral Point HSS-E - Steam Oxide Coated - Through Hole - No. 6 x 32

Engineered for precision threading in through-hole metalworking, the OSG UNC Spiral Point Threading Tap (No. 6 x 32) delivers reliable, high-quality threads with long tool life. Built for professionals and shops tackling demanding tapping tasks, it combines rigidity, heat resistance, and efficient chip evacuation.

• Threading Style: UNC spiral point design to push chips forward and maintain smooth cutting in through-hole applications.
• Material: High-Speed Steel with Cobalt (HSS-E) for enhanced toughness and heat resistance during heavy cuts.
• Coating: Steam oxide coating that reduces friction and provides rust resistance for longer tool life.
• Size & Fit: No. 6 x 32 through-hole tap, designed for standard UNC threads in through-hole applications.
• Through-Hole Performance: Specifically optimized for through-hole tapping with clean, consistent thread formation.

With the OSG UNC Spiral Point Tap, you can achieve fast, clean thread cutting in metal parts where holes pass completely through the workpiece. The spiral point helps evacuate chips efficiently, reducing clogging and extending tool life even on tougher materials such as steel and cast iron. The HSS-E composition delivers reliable performance under high heat, while the steam oxide coating minimizes galling and enhances lubricity for smoother, more repeatable threads. This tap is ideal for screw-fastener production, maintenance, and repair tasks in machine shops, automotive environments, and general manufacturing settings. For best results, pair with proper cutting fluid and a stable drilling setup to maintain thread accuracy and surface finish.
