Our DIN 371/376 TiN Coated Form Taps (also known as Fluteless Taps or Cold Roll Taps) represent the most efficient threading solution for ductile materials. Unlike traditional taps, these tools do not cut the material; instead, they displace it to form the thread profile.
The result is a compressed, high-strength thread with a superior surface finish. Combined with a Titanium Nitride (TiN) coating, these taps offer an ultra-low friction coefficient, preventing material galling and allowing for incredibly high production speeds in both through and blind holes.

Zero Chip Management: Since no chips are produced, there is zero risk of chip clogging in blind holes. This eliminates the #1 cause of tap breakage.
Superior Thread Strength: Because the metal grain flow is diverted rather than cut, the resulting threads have higher pull-out strength and resistance to stripping.
Exceptional Tool Life: Without sharp cutting edges to dull, and with the heat-shielding TiN coating, form taps typically last 3 to 10 times longer than cutting taps.
High-Speed CNC Performance: Optimized for synchronized tapping on modern VMC and HMC centers.
Form taps require materials with good "flow" characteristics (ductility).
Aluminum Alloys: Both cast and wrought aluminum (6061, 7075, etc.).
Low Carbon Steels: Mild steels and structural steels up to 900 N/mm².
Stainless Steel: High-ductility grades like 304 and 316.
Copper & Brass: Excellent results in non-ferrous, gummy materials.
HSSE-M35 Substrate: 5% Cobalt content provides the core toughness to handle the high pressure of the forming process.
TiN Gold Coating: Provides a surface hardness of 2300 HV, ensuring the lobes of the form tap maintain their precision for thousands of holes.
Rose-Box Packaging: Vacuum-sealed and protected in premium individual plastic tubes with high-viscosity anti-rust oil.
Q: Is the pre-tap drill size the same as for cutting taps?
A: NO. This is critical. Because you are displacing material rather than cutting it, you need a larger hole. For example, for M6 x 1.0, a cutting tap uses a 5.0mm drill, but a form tap requires a 5.5mm drill. Using a 5.0mm drill with a form tap will break the tool immediately.
Q: Can I use form taps for any material?
A: Form taps are ideal for ductile materials. They are not suitable for materials with low ductility, such as Gray Cast Iron or hard steels (>HRC 35).
Q: Do I need special lubrication?
A: Yes. Form tapping is a high-pressure process. High-quality tapping oil or high-concentration coolant is recommended to maximize the lifespan of the TiN coating.
