Dremel 4485 - Collet Nut Kit

This is a DREMEL Quick Change Nut/Collet Set which allows for quick and easy  
                   bit changes without the use of a wrench.                    
                                                                               
FEATURES: The quick change collet nut is made of steel and is knurled for easy 
            finger-tip bit changes.                                            
          Each collet is a slim, aluminum tube used for holding a bit.         
          Each collet features small identification rings around its shank.    
            These rings correspond with the size of the collet:                
              0 rings = 1/8"                                                   
              3 rings = 3/32"                                                  
              2 rings = 1/16"                                                  
              1 ring =  1/32"
