KATO Tang Break-Off Tools are for use with 1, 1-1/2, and 2 diameter length inserts.
For 2-1/2 and 3 diameter add a -30 to the end of the part number. For example, CAB-06-30 is a 6-32 tang break-off tool for 2-1/2 and 3 diameter inserts.
For insert sizes larger than 1/2" or 12mm use standard needle nose pliers to remove tangs.
