Engineered for precision blind-hole threading in metric fine pitches, the OSG Threading Tap delivers reliable performance for professional machinists. Its TiCN-coated, powder metal body and FORM E geometry optimize cutting action and thread quality.

• Size & Geometry: Metric fine thread M3.5 x 0.35, right-hand threading, designed for DIN371 blind-hole applications.
• Flute Design: A-Spiral flute aids efficient chip evacuation in blind holes, supporting consistent, clog-free cutting.
• Material: Powder metal substrate combines wear resistance with toughness for durable tapping tools.
• Coating: TiCN coating increases surface hardness and lowers friction to extend tool life and performance.
• Application: Optimized for high-precision tapping in blind holes across metal components and assemblies.
• Direction: Right-hand thread for standard tapping operations.

The combination of FORM E geometry and the TiCN-coated powder metal body translates to cleaner thread starts, tighter tolerances, and longer service life in demanding blind-hole tasks. The spiral flute and advanced coating work together to reduce heat and wear during high-speed tapping, improving cycle times and overall productivity. This tap is ideal for technicians and shops that require repeatable, high-quality metric threads in compact or recessed features without sacrificing tool longevity.
