HARFINGTON M8x0.75 Cobalt HSS TiCN Coated Plug Hand Tap - Metric Threading Tap For Stainless Steel & Tough Materials

About This Product

Tackle tough threading jobs with confidence using this HARFINGTON M8x0.75 metric plug hand tap, made from premium 6542 cobalt high-speed steel with a tough TiCN (dark silver-black) coating.

The added 5-8% cobalt boosts hardness to 67-68HRC, improving wear resistance, heat tolerance, and toughness—far better than standard HSS for cutting stainless steel, titanium alloys, high-temp alloys, and other challenging materials.

The TiCN layer outperforms TiN (gold) in hardness and reduces chip adhesion, oxidation, and peeling for cleaner cuts and longer tool life.

Straight flutes ensure fast downward chip evacuation, making it efficient for through-holes or shallow blind holes while delivering more complete threads than taper taps.

Specs: M8x0.75 thread, 6.2mm shank diameter, 71mm total length, 4.8mm square head, right-hand cutting.

Versatile for mild steel, aluminum, iron, copper, hard plastics, and re-threading damaged threads.

For best results, align properly, apply even pressure, back off periodically to clear chips, and use cutting oil or lubricant.

A reliable choice for machinists, hobbyists, or pros needing precise, durable metric threads.

Add this cobalt plug tap to your toolkit and enjoy smooth, accurate threading on tough jobs every time.
