Product catalog summary

Specifications:
The document outlines detailed specifications for threading tools, adhering to standards such as DIN 371 and DIN 376. It includes models like Z320VS-4, Z420VS-4, Z370VS-3, and Z470VS-3, specifying parameters such as diameter (Ø d1), pitch (P), lengths (l1, l2, l3), and diameter tolerances (d2 h6, h9).

Procedures:
It describes thread cutting and forming procedures, tailored for materials like austenitic stainless steel (DIN: 1.4301/ AISI 304). Methods include rigid tapping and the use of lubricants such as cutting oil and emulsion.

Standards and Norms:
The tools comply with standards like ISO DIN 13, ANSI B1.1, and DIN ISO 228 (BSP), and reference norms such as Norm DC and DIN 5156.

Recommendations:
For optimal performance, specific cutting speeds (Vc) are recommended, emphasizing the importance of process security in threading operations, particularly with tough materials.

Data Summary:
Tables provide detailed data on threading tool dimensions and performance metrics, including the number of threads achieved with various lubricants and cutting speeds.
