The OSG Threading Tap Metric A-Spiral Flute is a precision tapping tool designed for blind-hole applications. Built for demanding machining environments, it combines a TiCN-coated powder-metal body with exacting 6GX tolerance to deliver reliable, high-quality threads in M4 x 0.7 DIN371.

• Size and pitch: M4 x 0.7 DIN371 for standardized, precise threads
• Material: Powder-metal body for enhanced durability and wear resistance
• Coating: TiCN coating provides increased surface hardness and reduced friction
• Flute geometry: A-Spiral flute design enables efficient chip evacuation in blind holes
• Tolerance: 6GX class delivers a tight, repeatable thread fit
• Thread direction: Right-hand threading for common fastening applications
• Application focus: Specifically optimized for blind-hole threading in challenging materials and environments

This tap is engineered to maintain consistent thread quality over extended use. The TiCN coating and powder-metal composition work together to resist wear, extend tool life, and reduce downtime due to rework. The combination of A-Spiral flutes and precise 6GX tolerance ensures clean chips and accurate threads, making it a reliable choice for production settings where blind holes and tight tolerances matter.
