The OSG Threading Tap, Metric Fine A-Spiral Flute, is a precision tool designed for clean, accurate M10 x 1 threads in blind holes. Built for professional machinists and serious DIYers, it combines durable powder-metal construction with a TiCN coating to maximize life and performance in challenging deep-hole work.

• Threading specification: Metric fine thread (M10 x 1) designed for precise engagement in blind holes, DIN374 compliant.
• Flute design: A-Spiral flute optimizes chip evacuation in restricted cavities, helping prevent clogging and re-cutting.
• Material: Powder-metal substrate delivers toughness and wear resistance for repeated use in demanding materials.
• Coating: TiCN coating enhances surface hardness and reduces friction, supporting higher cutting speeds and improved heat resistance.
• Orientation: Right-hand thread for standard tightening and compatibility with conventional tapping setups.
• Application: Ideal for fine-threading tasks in metalworking where access is limited to blind pockets and internal threads are critical.

By pairing a spiral flute with a durable, coated substrate, this tap delivers reliable thread formation with longer tool life and consistent results even in tougher metals. The TiCN coating helps maintain cutting efficiency over time, reducing wear and heat buildup, while the powder-metal body provides a stable balance of strength and cost-efficiency. This tap is well-suited for repair work, prototype builds, and production tasks that demand precise, clean M10 x 1 threads in confined spaces.
