Types of white mirror punch holes
This is a circular blade with a cutting edge that has been polished many times after being machined by a lathe to improve the sharpness of the product. During the punching process, because the blade is sharp, the punching pressure due to friction is reduced, allowing the cutting surface to be sharp and the height accuracy to be improved.
Like the mirror-coated blades, it has high sharpness and is rust-free, and can punch adhesive materials and materials in the food industry.
