ER collects are the most widely used chucking tools in the Mechanics of today. Its versatility continues to grow. The rate of growth continues to increase. We provide various ER collets such as ER11, ER16, ER20, ER25, ER32, and ER40 collets. Also, we supply a great number of ER collet chucks for the ER collets, e.g. CAT50, CAT40, BT40, BT30, R8 Shank, Morse Taper Shank, Straight Shank, ISO40 Shank, Collet Blocks, 5C Shank, etc.
All Accusize ER collet chucks are designed and made in accordance with ISO 15488:2003(E). Especially the eccentric design of the inside of the collet nut is to help increase the capacity of the collet nut and improve the assembling efficiency of the entire tool kit.
Moreover, we have various ER collet and ER collet holder bundles that save your time of selecting collet sizes and ER collet holder types. E.g. MT2 Shank Er32 Chuck with 11Pc Collets Kit, 5C Shank ER40 Chuck with 15 Pc Collet Set, BT40 Shank and 12 pcs of Er32 Collet Set, etc. On the other side, we are increasing the number of types of ER collets and collet holders we carry. Meanwhile, we keep upgrading the quality, reliability, design and affordability of our professional tools.

The inside of the ER collet nut is intentionally designed like off-centering to help mount the ER collet much easier. It is in accordance with the requirements listed in ISO 15488:2003(E). If it is made symmetrical, the ER collet with the diameter larger than the inside size of the collet nut cannot be installed.
Assemble
Insert the ER collet into the nut at an angle. Lock it onto the eccentric groove of the collet nut and push it in. (Insert the cutter right after the step, before connect it to the holder/chuck/arbor.)
Inspection
Inspect the RPM of the ER collet, ER collet nut, ER collet holder/chuck/arbor, etc.
Dissemble
take out the tool bit, press the end of the ER collet until the collet off the position. Push it out of the nut. (after take out the nut out of the holder.)
