The OSG Threading Tap UNF A-Spiral Point is a high-precision tapping tool designed for through-hole UNF threads. Built for machine shops and precision manufacturers, it delivers clean, consistent threads with outstanding wear and heat resistance.

• Thread Type: UNF (Unified National Fine) threading with an A-spiral point for efficient chip evacuation and through-hole tapping.
• Material: Powder metal construction to deliver excellent hardness, durability, and resistance to wear and heat.
• Coating: TiCN coating reduces friction, improves cutting performance, and extends tool life at higher speeds.
• Thread Direction: Right-hand threads for standard fastening applications.
• Through-Hole Design: Specifically suited for through holes in accordance with DIN2184-1 specifications.
• Size / Length: No.3 x 48 — nominal size No.3 with an overall length of 48 mm for versatile use across multiple workpieces.

In practice, this tap helps you achieve precise thread depth and clean finishes even in challenging materials. The spiral point geometry pushes chips forward for smoother cutting and reduced clogging, while the TiCN coating supports higher-speed tapping with lower wear rates. The result is reliable performance in automotive, aerospace, and general precision manufacturing tasks where fine-pitch UNF threads matter.
