Yes, with a chain whip too.

Yes. No issues with Ultegra-6600

yes

Yes it will. I just did it myself, as an almost complete novice.

Yes but you need a chainwhip tool also

Yes as that's what I currently use

Yes - Shimano and SRAM are the same lockring.

Hi, This works fine on SRAM cassettes aswell as Shimano one

If anything says that it is "Shimano compatible" then it will work on SRAM. Shimano and SRAM have the same compatibility standards.

Not possible with this product, 40nm is nipped up to compress the spring washer then through a clockwise rotation equal to about 15 minutes on a clock face (from 1/4 past to 1/2 past! when looking from above) it's not very tight.

40nm is quite a lot, and would probably lead to stripping the thead on an alloy lock ring. just use good judgement. A good rule for approximate tightness of any thread is to tighten by hand without much force then tighten another 1/8 of a turn. For a cassette then check for any movement on the freehib body. remember you can always tighten more but if you strip a thread....problems.
Manufacturers torque values tend to be maximums, i do use a torque wrench and usually find that checking after i have tightened by hand and checked the component for any movement that the actual torque value is 1/3 under stated max value. hope this helps.

Torque is not preset. I guessed.

Use a torque wrench and if it is not preset stop at 40NM.

No; you need a Campag cassette removal tool.

No. Shimano is compatible with SRAM but NOT campag. Campag has a slightly different lockring pattern.

NO

Freewheels and cassettes are different things. This fit's cassette types - 8-9-10 speeds.

it fitted my 11-28 shimanno

It's a simple remove wheel, remove quick release skewer, insert guide pin through axle, line up lock ring with splines on tool, push home. Using a chain whip hold the cassette with the handle pointing the oposite way to the remover, push down on remover (lockrings are anti clockwise un do) should only be done back up firmly (40nm ish) make sure it's for the right cassette maker or it may not engage the splines.

This tool worked perfectly on my shimano ultra 10 speed cassette and was easily deep enough to engage with splines

yes

The locating pin requires a hollow axle, buy a remover which uses a spanner for solid axles.
