TiAlN Coated Roll Form Tap

Product Overview

Our AlTiN Coated Roll Form Taps adopt advanced cold forming technology without generating chips. Combined with high-performance AlTiN (Aluminum Titanium Nitride) coating, these taps deliver exceptional high-temperature resistance, low friction and excellent anti-adhesion performance. They are ideal for tapping hard-to-machine metals, especially stainless steel, alloy steel and heat-treated parts. Compared with TiAlN coated taps, our products feature longer service life, stable running and fewer replacements, perfectly matching high-volume automated CNC production.

Applicable Working Scenarios

  1. Deep hole & blind hole machining : No chip clogging risk, effectively avoid tap breakage.
  2. High-speed & continuous mass production : AlTiN coating withstands cutting heat for long-cycle operation.
  3. Precision component manufacturing : Produce smooth, high-strength threads with tight dimensional tolerance.
  4. Recessed cavity & confined space : Optional long shank design meets extended reach requirements.
  5. General machining workshops, OEM factories and metal fabrication lines .

Machinable Materials

  • Stainless steel: 304, 316, 316L, 430, duplex stainless steel
  • Alloy steel: 42CrMo, 34CrNiMo6, SCM435, 40Cr and other quenched & tempered alloy steel (≤ 38 HRC)
  • Carbon steel: Mild steel, medium carbon steel, high carbon steel
  • Non-ferrous metal: Brass, copper, aluminum alloy
  • Cold-forged & annealed structural steel

Recommended Pre-Drill Size Chart

Additional Notes

  1. AlTiN coating performs best at high cutting temperatures, suitable for dry cutting and semi-dry cutting.
  2. For stainless steel and high-hardness alloy steel, use high-quality extreme-pressure tapping fluid to further extend tool life.
  3. Pre-drill size shall follow the table strictly; improper hole size will cause excessive torque, thread defects or tap fracture.
  4. Custom sizes, special pitches, non-standard lengths and logo engraving are acceptable.
