Stuck bottom bracket time - Hollowtech with a plastic removal tool

Is there a better tool for the job?

I've got the right spanner, but Hollowtech seems to have come in different diameters and Shimano sell this plastic adaptor ring to fit it the spanner to the smaller diameter Ultegra one I've got.


I can't get much torque on it before the plastic splines start to strip

Is this sort of thing going to fit or will it be for the larger diameter bearings?
