The OSG Threading Tap Metric A-Spiral Flute is a high-precision tapping tool designed for blind-hole work, delivering reliable, repeatable threads in demanding metalworking applications.

• Material: Powder metal construction for enhanced durability and wear resistance in tough tapping conditions.
• Coating: TiCN coating increases surface hardness and reduces friction, extending tool life and maintaining consistent thread quality.
• Flute Design: A-Spiral flute promotes efficient chip evacuation, minimizing crowding and improving tapping efficiency in blind holes.
• Tolerance: 7GX tolerance class provides an extra-tight thread fit for precise, dependable assemblies.
• Size / Thread: Metric M12 x 1.75 tapping size tailored for standard metric threads in blind holes.
• Hole Type: Specifically engineered for blind holes (DIN 376), enabling clean, bottoming threads without through-holes.
• Hand: Right-hand threading aligns with conventional metric thread practices for most assemblies.
• DIN Standard: DIN 376 compatibility ensures broad interoperability with common fasteners and components.

Designed for engineers and machinists who demand accuracy and durability, this tap delivers tight tolerances and clean chip control. The combination of powder-metal substrate and TiCN coating helps maintain sharp cutting edges, even after numerous cycles, while the spiral flute design keeps chips moving away from the cutting zone for smoother, more consistent threads in blind holes. Whether you're building precision assemblies or performing high-volume production tapping, this tap supports reliable performance and repeatable results from the first hole to the last.
