Wielander+Schill Tool Box Punching Kit Ø 6.7 mm | 700143
Product Overview
The Wielander+Schill Tool Box Punching Kit Ø 6.7 mm (SKU: 700143) is a highly specialized, OEM-approved accessory kit designed for precision hole preparation in automotive collision repair. Modern automotive manufacturing utilizes ultra-high-strength steel (UHSS) and advanced aluminum structures that often prohibit traditional drilling, as drill bits create heat, burrs, and leave behind metal shavings that can cause corrosion or damage internal cavities.
This kit allows technicians to cleanly punch exact 6.7 mm diameter holes through hard structural panels, creating the perfect tolerance required for the subsequent installation of high-strength blind rivets. Engineered specifically to interface with the force-supporting PushPull PP 90 cylinder of the Wielander+Schill XPress 800 and XPress 1000 riveting systems, this 3-part kit delivers clean, factory-grade hole preparation in a fraction of the time it takes to drill.
Key Features
-
Precision 6.7mm Punching: Specifically sized to create the exact 6.7 mm diameter hole required by European OEMs for specialized high-strength blind rivets.
-
Drill-Free Hole Prep: Eliminates the use of drill bits, ensuring no heat-affected zones (HAZ), no sharp burrs, and zero metal shavings falling into enclosed structural pillars.
-
Ultra-Hardened Tooling: Both the K1 punch and B67 punching die are manufactured from industrial-grade, hardened tool steel to easily shear through advanced high-strength automotive steel (AHSS) and aluminum alloys.
-
SKR Punching Rings: Includes a pack of 50 sacrificial SKR punching crowns (rings) that assist the main punch in shearing the metal cleanly and evacuating the punched slug.
-
Seamless Integration: Designed exclusively to fit the Wielander+Schill PushPull PP 90 retraction cylinder, harnessing up to 90 kN of hydraulic force for effortless punching.

Ideal Use Cases & Applications
-
High-Strength Blind Riveting: Essential for preparing panels where specialized 6.5mm or 6.7mm structural blind rivets are required by OEM repair procedures (e.g., Mercedes-Benz, BMW, Tesla).
-
Structural Pillar & Rocker Panel Repairs: Perfect for use in enclosed cavities where traditional drilling would leave metal shavings trapped inside, leading to future rust and corrosion.
-
Multi-Layer Panel Joining: Highly effective at punching clean holes through stacked layers of high-strength steel or aluminum without misaligning the panels.
Common Questions (FAQs)
Q: Why does the kit include a 6.0 mm punch for a 6.7 mm hole?
A: The 6.0 mm K1 punch is the central driving pin. It works in conjunction with the 6.7 mm SKR sacrificial punching ring (crown) and the 6.7 mm B67 receiving die to cleanly shear the metal to the final 6.7 mm diameter. The SKR ring prevents the metal from distorting as the punch pulls through.
Q: Can I use this kit with a standard XPress 800 short-stroke cylinder?
A: No. This punching kit requires the specific retracting force of the PushPull PP 90 cylinder. Standard short-stroke cylinders only push, whereas the PushPull cylinder is required to cleanly pull the punch back through the thick structural metal after the hole is made.
Q: Are the SKR punching rings reusable?
A: No. The SKR punching rings (SKU: 700142) are consumable items. The kit includes 50 pieces to start. They act as sacrificial crowns during the punching process to ensure a flawless, burr-free edge.
