Recommendationd for the best type of 'blade' to put into an anglr grinder to cut through 'angle iron' much appreciated - available from Srewfix would be good.

They do work amazingly well. I was surprised how quickly one of those cut through a 1.5 inch stainless propshaft. It was so good I cut it again just for the enjoyment of using such an effective tool.
Wouldn't fancy cutting a lot of feet with one as they are quite noisy but for a quick job they are brilliant.

just make sure you wear leather gauntlets and a proper polycarbonate face shield. Slitting discs will break up if you lose conentration for a second.

I wouldnβt fancy cutting 7ft of 10mm base plate with a jigsaw. Much better to use a disc. (A lot of discs!!!)

And ear defenders, and if in a poorly ventilated shed, a dust mask. I prefer tig welding gloves (Toolstation for about a fiver), as I find I canβt grip it safely for long periods using heavy gauntlets.

I'm only removing the caravan towing hitch, all be it I'll be hanging over the stern so a fair warning about using safety gear.

If you really want to do a professional job cutting a boat in half then a Plasma cutter is the way to goπ www.r-techwelding.co.uk/plasma-cutter-r-tech-p30c/Will cut up to 12mm but a bigger one would be betterπ But for a tow hitch a slit disk will be fine. Don't use it for anything other than cutting as it will disintegrate.

and there we were, imagining you cutting a boat in half ................................
.............................. spoilsport!!
PS for thick steel, say 8mm or more, I would prefer to use a grinding disc.
I have just sold a 225mm grinder used for heavy steelwork, and for cutting concrete with a diamond blade. The inertia is evident when you squeeze the trigger - it takes 5 seconds to build up speed - and you need to hold it firmly and be aware of the gyroscopic effect.

I've used a 225 grinder with diamond disk for cutting a doorway in engineered bricks (wall was 3 bricks thick so cut needed to be from both sides plus a lot off bodging afterwards) - never again........

I handed my old Bosch 9" grinder along to a professional steelworker
It had done me proud had done a lot of work and still looked good but it's now too heavy for me to handle (it's their Millenium Special which weighs half as much again as the modern ones) 21 years old and still going strong.
anything I need to cut or grind now has to be a 115mm or plasma

A friend used a cutting disk to make an adjustment to my motor bike rack. All well and good then bang! the disk disintegrated. A piece of it went clean through the cratch cover of a boat moored nearby, a small piece neatly removed a piece of flesh from my arm and what I presume was a larger piece split his forehead wide open, hospitalising him. Not sure whether we were unlucky, he didn't know what he was doing or that this things happen from time to time. Either way, once bitten twice shy, I wouldn't use one personally.

Bloke I know used slitting discs to cut several porthole holes in the side of a 4mm thick steel cabin. He was fine. He's a pikey and knows how to handle power tools. He is also very detailed in his descriptions. He told me the disc will actually bend a bit but there is a limit to how far it will go before it comes apart.
As far as I know he's never been in hospital but at 60 he has shit hearing and knackered knees and bad eyes so probably not been very careful !
