HSS Forming Taps (Roll Taps) – Chipless, Stronger, Longer Life

Why Forming Taps Are Better Than Cutting Taps

Forming Taps (also called Roll Taps) do not cut material — they displace it by cold forming. This process creates threads with 20-30% higher tensile strength, no chips, dramatically longer tool life (often 5-10× longer than cutting taps), and excellent surface finish.

They are the best choice for ductile materials: aluminum, copper, brass, low-carbon steel, stainless steel, and even some titanium grades.

Amony offers three popular specifications that cover most production needs:

1. HSS-E Forming Taps, JIS Standard, TiN Coated

Most versatile model, JIS precision, excellent for aluminum, copper, low-carbon steel and stainless steel.

2. HSS-E UNC Forming Thread Tap, TiN Coated

American Unified Coarse thread, perfect for US standard parts in automotive, machinery and consumer electronics.

3. HSS-E Long Shank Forming Taps, TiN Coated

Extended shank (150–300 mm) for deep cavity forming in molds, large workpieces and hard-to-reach areas.

All taps are made from premium M2/M35/M42 cobalt HSS, with TiN coating as standard. Pre-drill size is typically 0.1-0.2 mm larger than standard cutting taps.
