No. Not for a 3/8 diameter without enlarging the socket. It will work for a 23/64 diameter without modifications.
Hello Steveo, 3/8 in. hex shank fits 3-jawed chucks. This will extend your reach by 12 in. when drilling with Milwaukee hole-saw arbors.
Take a pair of pliers from the FRONT on the bottom retainer (the tabs will be on the opposite side)of each side and bend up (or down). The tabs will slide through the holes.
Yes, you can. I have used more than that connected together. I recommend periodically checking the set screws to ensure they remain tightened as on a couple of rare occasions they became loose over time. Overall, this product worked well for me.
This is advertised as a 3/8" extension. This hex extension does fit a 3/8" chuck. The receiver end is too small to accommodate conventional 7/16" hex hole saw arbors nor self-feed bits.
The widest part of this extension's shaft is about 1/2"
No 1 set screw
