About ER20 Collets
ER20 collets are an industry standard (DIN 6499) self-extracting collet. They are available in 1/64" increments from 1/32" to ½" in diameter. They are also available in metric sizes from 1 mm to 12 mm. This holder is very nice for almost all milling and drilling operations.The ER20 collet is a self-extracting style. This means that the collet must be mounted into the nut first, then the nut and collet assembly are put into the collet holder. If these steps are not taken the collet and/or nut may be damaged and there will be very little holding capacity of the collet. A close inspection of the collet nut will reveal that it is not symmetrical. An area of the retaining ring is cut away. With the collet held at an angle, it is tipped into the cut-out area and will snap into place. With the collet correctly mounted in the nut, the collet will be pulled forward and out of the collet holder taper when the nut is slightly loosened, resulting in self-extraction.
