The OSG Threading Tap Metric A-LT-Spiral Flute is a precision right-hand tapping tool designed for blind-hole threads in miniature components. Built for reliability in tight spaces, it delivers clean, accurate threads with every pass.

• Thread Type: Metric M2.5 x 0.45, right-hand threading for standard internal threads in small-diameter parts.
• Flute Style: LT (Long Taper) spiral flute for superior chip evacuation in deep blind holes.
• Material: Powder metal construction providing high strength and durability in demanding cutting conditions.
• Coating: TiCN coating increases hardness and wear resistance, reducing friction and extending tool life.
• Application: Specifically optimized for tapping blind holes where access is limited and precise thread forms are essential.
• Compatibility: Suitable for high-speed machining environments and precision assemblies requiring dependable internal threads.

This tap is engineered to maintain form and finish under repetitive tapping tasks, helping minimize rework and downtime. The combination of powder metal toughness, TiCN wear resistance, and an efficient LT spiral flute translates to consistent thread quality, smoother cutting action, and longer tool life in small-diameter applications such as electronics enclosures, micro-mechanical assemblies, and compact machinery components.
