# K3 + K4 Punch and Forming Tool Set | \u00d8 8 mm<\/p>\n
**Part Number:** 700349<\/p>\n
This professional tool set, belonging to the Wiel\u00e4nder+Schill XSeries product family, has been specifically developed for the preparation phase of installing **Flow Form Rivet (FFR)** rivets. The set supports the process of punching, reshaping the material, and calibration, ensuring a perfect fit and optimal quality of the rivet joint.<\/p>\n
The tool set consists of durable components meeting the highest quality requirements, which guarantee precise and repeatable results during body repair work.<\/p>\n
## Product Description and Application<\/p>\n
The combined use of K3 and K4 tools is essential for the proper installation of FFR rivets with a diameter of 8.0 mm. The process consists of two main steps, which are realized by the two separate elements of the set:<\/p>\n
1. **Punching (K3):** The K3 punch precisely prepares the hole with the desired diameter.
\n2. **Forming and Calibration (K4):** The K4 forming head then gently reshapes the material around the hole and calibrates the edge of the hole so that the Flow Form Rivet can optimally adhere and fasten to the body components.<\/p>\n
This two-step process ensures that the mechanical strength and durability of the rivet joint comply with strict OEM (Original Equipment Manufacturer) specifications.<\/p>\n
