Description

Achieve precise, durable metric threading with the OSG Metric Spiral Flute Threading Tap. Designed for blind-hole tapping in metal, it delivers clean M6 x 1 threads with exceptional wear resistance and heat tolerance.

  • Material: HSS-E (high-speed steel with cobalt) for increased hardness and wear resistance.
  • Coating: Steam Oxide Coated Plus finish to improve lubricity, corrosion resistance, and tool life under high temperatures.
  • Flute design: Spiral flutes optimize chip evacuation, reducing clogging and fracture risk in blind holes.
  • Size and thread: Metric threading, M6 x 1 pitch, suitable for standard metric fasteners.
  • Application: Specifically engineered for blind-hole tapping in metalworking projects; compatible with both CNC and hand tapping operations.
  • Durability: Built to withstand repeated cuts, heating, and abrasive materials for longer life between changes.

By choosing this OSG tap, you gain dependable, accurate threads that engage securely with fasteners, minimizing post-cut finishing and rework. The cobalt-infused HSS and steam-oxide finish work together to resist heat and wear, extending tool life in demanding applications. The spiral flute design makes chip removal easier in blind holes, supporting deeper threads and cleaner finishes in a variety of metals. Ideal for machine shops and job sites where reliable, repeatable tapping is required for M6 x 1 components in assemblies, enclosures, and vehicles.
