The OSG Metric A-Spiral Flute Threading Tap is engineered for blind-hole applications, delivering precise M16 x 2 threads with exceptional durability. Designed for machinists who demand consistent, high-quality results in challenging materials, this tap combines robust construction with advanced coatings for reliable performance.

• Flute design: A-Spiral flute maximizes chip evacuation in blind holes, reducing plugging and boosting tapping efficiency.
• Material: Powder-metal substrate offers superior wear resistance and longer tool life in tough machining environments.
• Coating: TiCN coating increases hardness and lowers friction, extending service life under demanding cutting conditions.
• Tolerance: 7GX tolerance class provides an extra-tight thread fit for precise assemblies.
• Size and standard: M16 x 2, DIN 376 specification, ensuring compatibility with standard fasteners and parts.
• Hand: Right-hand threading for conventional clockwise tapping operations.

In practice, this tap delivers consistent thread quality in blind-hole work, with improved chip clearance and reduced wear over many cycles. The TiCN coating helps keep cutting forces predictable, while the 7GX tight tolerance ensures reliable mating with corresponding nuts and inserts. Ideal for precision applications in mechanical assemblies, automotive components, and fabrications where secure, accurate threads are essential, this tap supports efficient production and high repeatability across multiple jobs.
