Reciprocating Saw Blades for Suspension Bolts?

What tool are you using to get through them? Only reason I ask, is I started with an air saw but like you, had little impact on the bolts. Then I switched to an electric recipricating saw with Dewalt blades (from B&Q I think) and with some perseverance, I got through each of them. I'd allow 30 mins of heartache for each bolt though!
Also, don't be tempted to cut corners.... I thought by using a grinder with a 1mm cutting disk it would be quicker. I had to take the guard off to get it in the space and ... BOOM! ... the disk shattered, hit me in the face and needed 15 stitches from under my chin to my lip... on New Years eve too!
Hope this helps...

I'm using a reciprocal saw. I switched to the blades that TangoVTEC recommended; they are miles better than the ones I was using but I'm still taking a long time to get through a bolt, and I'm still getting through blades. I'm using WD40 as a ghetto cutting fluid. It took about 60 mins to get through one side of a bolt and 90% of the second side. Not sure if I'm just doing something wrong here. I also don't have the clearance to cut the bolt without cutting the bushing on one side - the other was fine though.
The Internet™ seems to suggest that a Freud Diablo Extreme Metal Cutting blade is the way to go - tungsten carbide teeth and seems massively more potent than anything else. Problem is they seem to be stupidly expensive and completely unavailable in the UK.

I cut two 150mm RSJs with those Bosch blades. The trick is take your time as the blades hot up very quickly and get blunt. Cut for a minute, rest for 5 or 10 minutes. BTW WD40 is crap for that purpose, use engine oil - any will do.

i use snap-on blades and it usually takes 1 blade per bush and 1 blade for both caster it's the rubber of the bush that trashes the blade, the main thing is to run the saw slow, the faster you run the saw the quicker you'll trash the blade and wd40 is as much use as a chocolate fireguard you need proper cutting fluid

The rubber increases heat,that makes sense
