The OSG Threading Tap Metric A-Spiral Flute is a precision tool designed for blind-hole threading, delivering consistently tight M3 x 0.5 threads for machinists and fabricators who demand reliability in challenging environments.

• Size and pitch: M3 x 0.5 threading for metric blind-hole applications
• Threading design: A-Spiral flute with right-hand thread to optimize cutting action and chip evacuation in blind holes
• Material: Powder metal substrate engineered for durability and precision
• Coating: TiCN coating to increase surface hardness and reduce friction during tapping
• Tolerance: 7GX class delivers an extra-tight thread fit for critical assemblies
• Standards: DIN371 compliance to align with common threading specifications
• Chip evacuation: Spiral flute design promotes efficient debris removal and minimizes clogging

With its TiCN coating and powder-metal construction, this tap offers extended tool life and dependable performance across repeated blind-hole tapping tasks. The combination of 7GX tight tolerance and the A-Spiral flute ensures clean, precise threads with reduced rework, even in tight-access locations or tougher materials. This makes it an excellent choice for precision assemblies, jigs, and fixtures that require durable, repeatable threading results.
