    ER UP Collet Test

    The picture above is a standard ER collet and a Stainless Steel Collet that were submerged in Chicago tap water for 3 months. The stainless collet showed no corrosion anywhere compared to the standard collet. collets

    420 Stainless is a 12% Chromium high carbon material which provides high hardenability and superior corrosion resistance. 420 Stainless allows us to harden the collets to Rc45, similar hardness as most standard ER collets in the market today.
