What is Tip Size for 71139-ND? Will it able to hold 4 mm Micro Bits?

Hello,

This part can only fit 1/4” bits, unfortunately this will not work with 4mm bits.

Hi ssankdasariya,

If you are looking for an adapter which converts a 1/4" driver to handle 4mm Micro Bits, here are a couple of options:

  • 75802 4mm Micro Bit to 1/4 drive insert bit adapter – magnetic

  • 75803 4mm Micro Bit to 1/4 drive insert bit adapter – non-magnetic
