TiN hard-coating punch
TiN hard-coating punch
(OP)
Is there any benefit to coating punches with TiN? I've seen it on drill bits. A rep suggested it as a method to increase the life of our tooling. We punch 0.050" wide by 1.25" slots in 0.050" thick SS304. The punches don't last very long and cost a bundle to replace because they are a custom shape.
Anu information or help would be welcome !!
Thanks in advance !!

coco...I would agree that a coating would most likely not help a chipping problem. Finer grain or higher cobalt content would be the way to go.
