Prehardened EDM Blanks

We use prehardened tool steel blanks in our EDMs. The blanks are hardened and ground. We just pull the right thickness off of the shelf and indicate it in.

These blanks enable us to produce a completed tool in just a few hours. We just burn it, then wire it and its done.

There is no need to buy individual pieces and machine or heat treat them. It is a huge time savings for us.
