Punching Applications

Punching

More bang for a buck! That's the simplest way to put it. Putting a coating on a punch will make a punch last 8 - 10 times longer.

In punching applications, most of the wear is on the side of the punch as it is being stripped out of the sheet metal. With a coated punch, the edge holds up much longer, side wear and galling are greatly reduced, and the coating is still there to provide the same benefits even after the punch is sharpened. In addition, one usually doesn't have to remove as much material to get a sharp edge compared to an uncoated punch.

Alpha™, TiCN and TiN are the primary coatings we offer for punching applications (please see the "Coatings Offered" pages for more detailed information on these three coatings).

The typical lead-times are one to three days for Alpha™ and one to five days for the other coatings.

Have you ever wondered why tooling and steel suppliers downplay coatings?

What do you think would happen to their sales figures if all their customers were suddenly getting ten times the tool life?

We coat many different types of punch materials, including A-2, D-2, M-2, etc. Some customers are concerned about drawing back some tool steels during the coating process. This may happen with some materials, but it usually doesn't affect the performance of the punch (please see FAQ for more information).
