Description

The OSG Threading Tap Metric A-Spiral Point is a right-hand through-hole tap built for high-speed, precision threading across a range of materials. Designed for through-hole applications, it delivers clean, consistent threads with efficient chip evacuation in demanding production environments.

  • Size and standard: M22 x 2.5 metric thread, optimized for through-hole tapping per DIN 376.
  • A-Spiral Point design: aggressively pushes chips ahead of the tool to minimize clogging and improve threading efficiency.
  • Material: Powder metal substrate delivers enhanced wear resistance and durability under heavy cutting conditions.
  • Coating: TiCN coating reduces friction and improves heat resistance, extending tool life at higher speeds.
  • Thread direction: Right-hand thread configuration for common machining setups.
  • Through-hole suitability: Specifically engineered to produce reliable threads in through-hole applications with consistent results.

With its combination of a rugged powder-metal body, hard-wearing TiCN coating, and chip-clearing spiral point, this tap maintains smooth cutting action even in tougher materials and at higher feed rates. You can expect precise, burr-free threads that meet tolerance needs, reduced downtime from cleaner chip evacuation, and longer tool life that lowers overall tooling costs. This makes it a strong choice for automotive, machinery, and general fabrication projects requiring dependable M22 x 2.5 through-hole threads.
