Tungsten Steel Pentagonal Cutting Blade – 5-Sided Carbide Knife for Valve-Mouth Bag Cutting

This tungsten steel pentagonal cutting blade is a specialized industrial knife designed for valve-mouth bag cutting and packaging machinery. Its five-sided geometry provides multiple cutting edges and is suitable for machines requiring a durable, wear-resistant cutting blade.

The blade is manufactured from high-quality tungsten carbide / tungsten steel material, providing high hardness, excellent wear resistance and long service life compared with conventional steel cutting blades.

Designed for Valve-Mouth Bag Cutting

The product is specifically intended for valve-mouth bag cutting applications (阀口袋切割专用). It can be used as a replacement cutting component in compatible industrial bag-making, packaging and processing machinery.

Five-Sided Pentagonal Design

The distinctive pentagonal blade design provides multiple cutting edges around the blade. Depending on the machine design, another cutting edge can be positioned for use when an existing edge becomes worn, helping improve blade utilization and service life.

Tungsten Carbide Construction

Tungsten carbide is widely used for industrial cutting tools because of its high hardness and resistance to abrasive wear. This makes the blade suitable for repetitive cutting operations where conventional blades may wear quickly.

Important Size Information

Pentagonal cutting blades are manufactured in different outer dimensions, thicknesses, center-hole profiles and positioning-hole arrangements. Compatibility cannot be determined from the blade shape alone.

Before ordering, compare the blade's overall dimensions, thickness, center mounting hole, positioning-hole diameter, hole spacing and cutting-edge geometry with the original blade installed in your machine.
