OSG Threading Tap Metric A-LT-Spiral Flute is a durable right‑hand tapping tool engineered for metric threads in blind holes. Designed for machinists and engineers who demand reliability in deep cavities, it pairs strong powder metal construction with advanced coating for extended life.
- Size and Thread: M20 x 2.5 metric thread with right‑hand orientation for standard assemblies.
- Material: Powder metal body provides high strength and toughness for demanding metals and heavy use.
- Coating: TiCN coating increases surface hardness and wear resistance, while reducing friction during cutting.
- Flute Design: LT (Long Taper) spiral flute enables superior chip evacuation in deep blind holes, helping prevent packing and breakage.
- Application: specifically optimized for blind-hole tapping to produce clean, accurate threads in recessed pockets.
- Performance Focus: engineered for stability in high‑speed machining environments, delivering consistent thread quality over extended tool life.
This tap supports efficient, repeatable threading where accessibility is limited. The combination of a robust powder metal core, the wear‑resistant TiCN coating, and the LT spiral flute translates to fewer tool changes, less rework, and more reliable threads in critical assemblies. Ideal for metalworking shops and production environments tackling deep, blind‑hole threads in automotive, aerospace, and general engineering applications.
