The OSG UNC A-Spiral Point threading tap is a precision right-hand tool built for through-hole applications requiring 5/16-18 UNC threads. Designed for durable performance in metalworking, it delivers reliable, clean threads with efficient chip evacuation.

• Size and thread: 5/16 x 18 UNC, right-hand threading
• Design: A-Spiral Point geometry for efficient chip control in through-holes
• Material: Powder metal substrate for enhanced wear resistance and durability
• Coating: TiCN coating to improve heat resistance and extend tool life
• Through-hole applicability: Optimized for tapping through-holes (DIN2184-1 specification)
• Standards: UNC threading aligned with DIN2184-1 requirements
• Orientation: Right-hand tap for standard clockwise threading

This tap is ideal for production runs and repair work where through-holes are common, offering higher cutting speeds, consistent thread quality, and longer tool life thanks to the TiCN coating and durable powder-metal body. It helps machinists achieve precise, repeatable threads in a variety of metals while reducing downtime and maintenance.
