Multi tool to cut pipe

I have to cut a pipe in a very tight and awkward position. The only way this can conceivably be done is by using a multi tool. The problem of course is the cut won't be straight and I'm wondering how this may affect the joint when soldered and whether the joint will fail.

Why won't it be straight? If it's that tight to get to, how are you going to be able to solder it safely?

I can get it close enough, but it's a multi tool so it;s inevitable there will be some deviation.
 
1. Make sure the pipe is completely empty of water, particularly if using a mains powered multi-tool.
2. Cut it as straight as you can.
3. Make sure you deburr the cut edges inside and outside the pipe.
4. If it gets cut at a slant, provided the shorter and longer sides aren't more than a few mm different (say 4 or 5), it will be fine soldered into a normal fitting.
5. Consider using a file to square up the ends before deburring.

Sounds like you doubt your ability, practice first but as asked earlier how are you going to solder it, tight against what?
 
Some photos of the pipe, showing its position, and length from the nearest immovable fixing on each side, might be informative
 
Normally a pipeslice can do the job...rotate it with pump pliers.
 
Get a piece of insulation tape and wrap it around the joint to provide a straight line. Cut with multitool using HSS or bimetallic blade. That should cut within 1mm of straight which will be good enough. I've done it myself.
 
All those copper fillings will find there way into the steel radiators....and can cause pinholing.
