The OSG Threading Tap is a precision solution for tapping metric threads in blind holes, built for engineers and machinists who demand reliability in compact components. With its A‑Spiral flute design, Form E geometry, and TiCN coating, this tap delivers consistent threads in demanding, high-speed operations.

• Thread Size & Type: M3 x 0.5, right-hand threading for standard metric applications.
• Flute Design: A‑Spiral flute with Form E extended flute length, optimized for deep blind-hole tapping.
• Material: Powder metal construction providing high strength and wear resistance for repeated use.
• Coating: TiCN coating increases surface hardness, reduces friction, and extends tool life in abrasive materials.
• Application: Specifically designed for blind holes, aligning with DIN371 specifications for form and geometry.
• Chip Evacuation: Spiral flute geometry promotes efficient chip removal, lowering the risk of tap binding or breakage.

This tap helps you achieve precise, clean threads in tight cavities while resisting wear in demanding production environments. The extended Form E flute length enables deeper hole tapping without compromising thread quality, and the TiCN coating supports higher cutting speeds and longer intervals between index changes. Powder metal construction balances toughness and wear resistance, making it suitable for repeated use in small-diameter, high-precision applications such as electronics enclosures, automotive interior parts, and compact mechanical assemblies.
