The Metric A-Spiral Flute Threading Tap from OSG, Form E, is a high-precision tool designed for reliable blind-hole tapping in metal parts. Crafted from powder metal and TiCN-coated for demanding production environments, it delivers strong performance for M22 x 2.5 threads with a right-hand orientation.

• Brand: OSG
• Size and pitch: M22 x 2.5 (metric thread, 2.5 mm pitch)
• Flute design: A-Spiral Flute, Form E for extended flute length in deep blind holes
• Material: Powder Metal for high strength and wear resistance
• Coating: TiCN coating to increase hardness and reduce friction
• Direction: Right-Hand threading
• Application: Intended for blind-hole tapping, compliant with DIN376

The extended flute length of the Form E design enhances chip evacuation in deep blind holes, reducing the risk of tap breakage and boosting overall machining efficiency. The TiCN coating minimizes friction, enabling higher cutting speeds and longer tool life on tougher materials, while the powder-metal core provides the durability needed for continuous production. This tap is ideal for precision threading in automotive, aerospace, and general engineering applications where dependable M22 x 2.5 threads are essential.
