The proper technique is not to use a spanner. Clamp a vice to a hut door. Secure tool in vice jaws then slide onto freewheel. Using hands on wheel/tyre rotate anti-clockwise. This gives more leverage than even the largest adjustable spanners which would be the second best suggestion.

hi I am not 100 percent sure on your question but as a general rule cassettes produced after 1980s use Hg(hyperglide) removal tool , I think yours is 35mm , you would be better off getting a park tool they are made and described accurately to fit XTR disk brakes
