The Carmex Threading Tap with Spiral Flute is a precision metric tapping tool designed for professionals and serious hobbyists who need reliable, clean threads in challenging materials. Built for M8 x 1.25 applications, this HSS-E tap delivers solid performance in demanding metalworking tasks.

  • Thread size: Metric thread for M8 x 1.25 applications, ensuring compatibility with common metric workpieces.
  • Material: HSS-E (high-speed steel with cobalt) for enhanced hardness, wear resistance, and heat tolerance.
  • Flute design: Spiral flute improves chip evacuation, reduces clogging, and supports smoother cutting progress.
  • Cutting geometry: Supercut tap geometry delivers accurate threads with consistent results across tough materials.
  • Durability: Cobalt-enriched alloying strengthens the tap for longer tool life in high-speed threading.
  • Application versatility: Suitable for precision threading in metalworking, fabrication, and repair work where metric threads are required.

By combining a spiral flute with the durability of HSS-E, this tap minimizes heat buildup and chip-related issues, helping you achieve true, burr-free threads with fewer passes. It’s an ideal choice when you need dependable performance on demanding metals and a tool you can count on for recurring metric threading tasks in professional workshops or serious DIY setups.
