If it is like a standard adapter, it screws into the spindle like a bit would. The bit then goes through it and is held by the setscrew on the upper section. It should not be tightened too much or the burnisher/adapter will not move up and down smoothly. Only the top that holds the bit moves.

If with the bit set as far down in the adapter as it can go and still be held by the screw, the tip does not protrude from the nose, you will have to remove the micrometer by unscrewing it.
Remember that you have to get the micrometer back to the same spot afterwords or your bits will be heighted wrong. My trick is to screw the micrometer all the way on till it stiffens. Now unscrew it till you pass '0' once then down to 10. You are now set to .010 depth and the bits should be readjusted to the '0' now set. Doing this will assure you that every time you remove the micrometer, it goes back in the same spot.
