BIG Kaiser offers a variety of collets.
In 1987, BIG Daishowa was the first company in the world to laser mark the collet grade on every collet.
Each ERC and New Baby collet is inspected twice (0° and 180°) at 5 times diameter to guarantee the runout accuracy of 1 micron at the nose, and 3 microns at 4xD. The "AA grade" is marked on only those collets that pass the inspection process for accuracy.
