Description
The OSG Threading Tap is a precision metric tool engineered for dependable blind-hole threading in small-diameter parts. Designed for machinists and engineers who demand consistent, clean threads at M2.3 x 0.4, it combines durability with efficiency for demanding applications.
- Size and pitch: M2.3 x 0.4 for micro-threading in compact components
- Material: Powder metal construction delivers high strength and wear resistance
- Flute style: Metric A-Spiral Flute, Form E with extended flute length for deeper blind holes
- Coating: TiCN coating increases surface hardness, reduces friction, and extends tool life
- Orientation: Right-hand threading optimized for standard blind-hole tapping
- Application: Specifically designed for blind holes in DIN371 applications
The extended flute length of Form E plus the spiral flute design provides efficient chip evacuation, minimizing tap binding and reducing the risk of breakage during deep-threading runs. The TiCN coating enhances performance in high-speed, demanding operations, helping you maintain consistent thread quality and finish. Built from durable powder metal, this tap stands up to repeated use in challenging materials while delivering precise, reliable threads in tight tolerances.
