Poly-Di® Polycrystalline Diamond Dies
When die life and wire production efficiency take precedent over wire surface finish, consider a Poly-Di wire die.
Poly-Di wire dies are manufactured with polycrystalline diamonds, a durable synthetic material with a highly polished surface finish that minimizes friction for an exceptional resistance to die wear, cracking and breakage.
You get significantly longer die life, excellent wire roundness and highly predictable die wear with a good wire surface finish.
