Tool recommendations (UK) for torgue/impact bike servicing

[iceman]

I have a fairly comprehensive socket set (for nuts, screws, etc) but I'm contemplating working on the clutch/belt/pulley, etc so could do with some tips on suitable, good but not very expensive tools for such work - such as impact drivers, torque thingy-m-jiggy, electric screw-driver that may have some of that functionality. It would be good to have a minimum set such as get away with 2 tools rather than 3, but rather than purchase the wrong thing or crap-ware, any recommendations?
Does an electronic screwdriver/impact tool work with normal bits from a large socket set or do they need their own make or bits?

Impact wrenches require sockets that are designed for impact wrenches; harder metal. They are labeled as such. Using regular sockets with them is dangerous because the may break and turn into missiles.

I started off with a manual impact wrench which you use by striking it with a hammer. That pushes & torques the bolt. Later I got an electric impact wrench; what a godsend ...

When I had a Burgman 400, I built my own variator tool to hold it still while removing/replacing that bolt. (for replacing the belt)

Impact tools are better for large stuff. These bikes are tiny composed of alloys that will strip in the wink of an eye
the homemade variator tool-good idea
sometimes though an impact might be the only solution-like a clutch?
and why do manufacturers still insists using Philips head screws
you can't over torque them and you can't get them out

You'll see impact tools used for variator/clutch removal in videos online.
Their use is questionable for the job.
Would you hit the end of your crankshaft repeatedly with a hammer...?

Far better imo to use the correct holding tools which are far cheaper and just as easy to use.
For the variator you need a two pronged holder and for the clutch drum a large strap wrench will suffice.
Both can be had for a combined total of around £20 (the pair)
