How do you attach a Bosch (SDS bit) to a wedge bolt to spin it to create a shoulder to pull it out? The only threaded SDS attachments I've been able to find are taps.

Wedge anchor removal (by Greg German)


He suggests reaming out the 3/8" coupler nut to 1/2". I found an sds-3/8" adapter and just had to tap 24 tpi threads into one end of the coupler nut for it to fit. Either way should work. Here's one of the adapter tools.
