The OSG Metric A-Spiral Flute Threading Tap is a precision tool built for tapping blind holes with reliability and consistency. Designed for M12 x 1.75 right-hand threads, it’s ideal for production environments where deep holes and tight tolerances matter.

• Flute Design: A-Spiral flute optimizes chip evacuation in blind holes, reducing clogging and allowing deeper taps with cleaner finishes.
• Material: Powder metal body delivers a balanced combination of toughness and wear resistance for repeated use.
• Coating: TiCN coating increases surface hardness and lowers friction, extending tool life in demanding materials.
• Size & Thread: Metric M12 x 1.75, right-hand threading for standard machining applications.
• Application: Specifically suited for threading blind holes, helping achieve accurate internal threads in limited depths.
• Standard: DIN 376 compatibility ensures reliable fit within standard tapping practices.

With this tap, you gain predictable, high-quality threads in blind-hole workpieces, reduced heat and wear buildup, and longer service life under repetitive production. The TiCN coating and A-Spiral flute work together to improve performance during high-speed tapping, while the durable powder metal construction provides solid value for frequent use. It’s a dependable choice for shops needing consistent hole quality, reduced downtime, and smoother tooling transitions in metalworking workflows.
