Pioneer has updated our collet offering to meet the high demands of precision cutting tools and high performance applications.
Note: Due to extreme cost increase by supplier GERC collets will be discontinued April 2019.
Pioneer Stainless Steel Collets are only available in a 5 micron (0.0002”) TIR @ 3D.
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.
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.
Available in ER11-ER32 in select sizes.
