ER series collets are used with both HSK 63F and some ISO-30 toolholders. ER Collets are a higher angle than SYOZ or RDO Series collets and in our experience provide less holding power depending on the application. Ask us we may have an option to offer you a conversion to the SYOZ toolholder style. The size of the collet should match the shank size of the CNC router bit. Also sometimes known as DR, RD, ESX, AR, & BR style collets. 

To use: Snap collet into the nut before threading the nut onto the spindle or tool holder, then insert the router bit to the desired depth, hand-tighten, then torque to proper tightness ideally with a torque wrench. (Torque wrenches available upon request).
