i used a 3/8 inch spade bit, tight but you tap them in place with a plastic mallet after putting in a small amout of j-b weld. since the ahrends grips have no washer it is necessary to drill a small hole all the way through to be able to tap them out from the back untill you drill a little at the time to get them to fit flush. it took 30 minutes.
practice on a piece of scrap wood first.
