   Hi,
   Couple of thoughts. First you drilled too large for the holdfast to bite in. Redrill or more likely rout for an even larger hole and glue in a bushing to this hole. The holdfast has to fit the ID on that bushing then for it to hold tight.

   Or inlay a piece of steel into your bench top [steel is dangerous on a bench top so be aware, you could try brass but it's gonna dent up fast I think] that is the right size for the holdfast.

   You just need to make a smaller hole so the holdfast bites into a larger area. Good luck.
