The OSG Threading Tap Metric A-OIL-Spiral Flute is a high-performance internal threading tool engineered for blind holes, built for production environments that demand precision and durability. Sized for M18 x 2.5 threads, it combines robust materials with advanced coatings to deliver consistent results.

• Material: Powder metal construction delivers enhanced toughness and load-bearing strength for repeated tapping without premature wear.
• Coating: TiCN coating increases hardness and wear resistance, reducing friction and extending tool life in demanding materials.
• Flute Design: A-OIL spiral flute promotes efficient chip evacuation in deep or blind-hole tapping, minimizing clogging and heat buildup.
• Thread Direction: Right-hand (RH) threading for standard internal threads in a wide range of applications.
• Size and Standard: Metric M18 x 2.5, designed to DIN 376 specifications for reliable interchangeability with compatible tooling.
• Application Focus: Specifically optimized for blind-hole tapping, delivering smooth, defect-free threads in challenging depths.

This tap is ideal for manufacturers and machinists working in automotive, aerospace, electronics housing, and general engineering where deep, clean blind-hole threads are critical. The combination of powder-metal strength, TiCN wear resistance, and chip-clearing spiral flutes reduces downtime, improves thread quality, and supports higher production throughput. For repeatable accuracy and longer tool life in tough drilling environments, this OSG tap provides a dependable solution that stacks up to the demands of modern machining.
