OSG Threading Tap - Metric Forming Tap (Roll) HSS-E - TIN Coated - Fluteless - M2.5 x 0.45

The OSG Metric Forming Tap is a roll-forming, fluteless tapping solution designed for precision small-diameter threads. It’s ideal for machinists and production environments that demand clean, strong M2.5 x 0.45 threads with reliable, long-lasting performance.

• Material: HSS-E (high-speed steel with cobalt) for enhanced heat resistance and longevity.
• Coating: Titanium Nitride (TIN) coating to reduce friction and extend tool life.
• Design: Fluteless geometry that forms threads by deformation, delivering precise, burr-free results.
• Process: Thread forming (roll) action that creates threads without cutting chips, improving surface finish and consistency.
• Size: M2.5 x 0.45, metric standard for small-diameter fasteners.
• Drive: Square drive end for secure engagement with standard taps and wrenches.
• Durability: Built for high-volume production with dependable wear resistance and long tool life.
• Brand technology: Leverages OSG’s advanced forming tap technology for repeatable, high-quality results.

Thread forming taps like this one deliver stronger load-bearing threads by deforming the material rather than removing it. The chipless forming process simplifies secondary operations, reduces debris, and minimizes post-processing. The TiN coating lowers friction and dissipates heat, helping maintain tight tolerances across production runs. With a robust HSS-E core, this tap is well-suited for durable performance in a range of metals, making it a reliable choice for precision assemblies, electronics housings, and light-to-medium duty mechanical components.
