Car seat cushion single-layer circular hole hollow discharge punching knife empowers interior cutting and processing

Zhongqi Precision Single layer Circular Hole Punching Knife is specially designed for punching single-layer flexible materials such as leather, clothing, automotive interiors, foam, etc. It adopts SKH55 high-speed steel and hollow discharge structure, balancing durability and processing efficiency.

The cutting tools are divided into two standard specifications: 7 × 13 (outer diameter Φ 7mm) and 6 × 13 (outer diameter Φ 6mm), with a unified total length of 13mm and a clamping section of 7mm. They are compatible with most CNC cutting equipment tool holders and easy to install. Cone shaped precision grinding of the cutting edge, smooth punching surface without burrs, and thin material processing without tearing or fuzzing.

The entire range covers aperture sizes ranging from 0.8 to 5.0mm, with both models available in stock aperture sizes and support for customized non-standard aperture sizes. The 7 × 13 models cover a full size range of 0.8 to 5.0mm, while the 6 × 13 models are equipped with mainstream micropores and mesopores. Special pore sizes can be processed as needed, suitable for various processing needs such as tag holes, breathable holes, positioning holes, etc.

The tool substrate is made of SKH55 high-speed steel, which is strengthened by heat treatment, has high hardness and good toughness, and is not easily broken by high-frequency stamping. The cutting edge is durable and wear-resistant, greatly reducing the cost of tool replacement. Core hollow straight discharge design, punching waste is smoothly discharged from the inside of the blade body, eliminating material blockage and stopping, adapting to continuous operation of automated assembly lines, stabilizing the accuracy of circular hole size, and reducing the loss of defective products.

Suitable for non-woven fabrics, thin leather EVA、 Single layer materials such as film and luggage fabrics are punched, and regular specifications are available for quick delivery. The outer diameter, aperture, and length can all be customized non-standard, making it the preferred punching tool for cost reduction and efficiency improvement in the cutting and processing industry.
