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 uncoated or TiN coated taps, our products feature longer service life, stable running and fewer replacements, perfectly matching high-volume automated CNC production.

Applicable Working Scenarios
- Deep hole & blind hole machining: No chip clogging risk, effectively avoid tap breakage.
- High-speed & continuous mass production: AlTiN coating withstands cutting heat for long-cycle operation.
- Precision component manufacturing: Produce smooth, high-strength threads with tight dimensional tolerance.
- Recessed cavity & confined space: Optional long shank design meets extended reach requirements.
- 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
(Optimized for roll forming process; ensure proper thread profile and low tapping torque)
Metric Thread (Standard Pitch)
| Thread Size | Pitch (mm) | Recommended Pre-Drill Diameter (mm) |
|---|---|---|
| M3 | 0.5 | 2.80 |
| M4 | 0.7 | 3.70 |
| M5 | 0.8 | 4.60 |
| M6 | 1.0 | 5.50 |
| M7 | 1.0 | 6.50 |
| M8 | 1.25 | 7.40 |
| M10 | 1.5 | 9.30 |
| M12 | 1.75 | 11.10 |
Additional Notes
- AlTiN coating performs best at high cutting temperatures, suitable for dry cutting and semi-dry cutting.
- For stainless steel and high-hardness alloy steel, use high-quality extreme-pressure tapping fluid to further extend tool life.
- Pre-drill size shall follow the table strictly; improper hole size will cause excessive torque, thread defects or tap fracture.
- Custom sizes, special pitches, non-standard lengths and logo engraving are acceptable.
