Spanner for 0.8kW er11a spindle

Hi guys,
The spanner I was sent has slowly wore away and now it just spins round the shaft rather than grip into the indent.
I'm not 100% sure where to purchase another one from.. when I search for ER11 spanner etc. I just get links to the larger spanner for the actual nut. I'm looking for the other one, to stop the spindle spinning as I try and tighten the nut.
Any ideas? I've tried a 13mm spanner here but it's too small.. and my 14mm is too loose.


Many thanks for any help!

between the two would be a 17/32" or grind a fraction off jaw of an old unwanted 13mm

Cheers.. I took a smidgen off an old 13mm and all was well again.. much easier with a decent spanner too.. rather than the thin little thing I was sent with it.
So I managed to get my bank holiday project finished in the end.. cheers!
