Aren't you satisfied with just a simple coating? By adding "polishing," the lifespan increases to 7.6 times.

We will publish the results of the lifespan comparison test between the coating-only case and the case where polishing is combined with the coating. The unprocessed pierce punch had a lifespan of 17,000 shots, while the coating alone achieved a lifespan of 50,000 shots. However, by adding "polishing," it jumped to 130,000 shots. This test demonstrates that the final lap after coating significantly reduces surface roughness (Rz0.32) and dramatically decreases friction resistance. High-quality surface treatment requires appropriate groundwork and finishing polishing. *Check out the materials packed with astonishing lifespan test data now.
