The makers set the speed, only var one I seen was a black and deckerMake sure you do not exceed the recommended rpm.as they can and do explode ,
i have a makita and a bosch 115mm grinders . don't like the shape of the bosch ,not nice to hold . i've had a switch go on a makita before now . have used these skinny discs exclusively since i first saw them ,in Portugal. a year later they brought them out in the UK, i can remember the shops giving away individually wrapped blades as free samples . i also use one of these . the blades seem a bit dear ,but i found a way of extending blade life ,so they're not so bad .https://www.screwfix.com/p/evolution-rage4-1250w-185mm-electric-chop-saw-230v/97351
i have seen 9'' skinny blades and i'll never be brave enough to try one
The cut edge would be exposed and depending on how the alloy was prepped would have a factor if it chips or not.Hi Nigel,
If I was to use that chopsaw on powder coated aluminium extrusion, would it be likely to chip the powder coat?
No guards on them.When you go into the finer finish most are vari speed.View attachment 101250View attachment 101251
On the grinder yes but not on the mop .No guards on them.

not sure tbh ,but i think if you wrapped it with a couple of layers of masking tape and took it slowish ,it would be ok ,after all the coating is a resin so i imagine it's flexible enough not to shatter .Hi Nigel,

on the other hand ,an angle grinder might cause burning
You can buy a bench tool for angle grinders which looks like a wood saw, just clamp it in and away, as nig says tape the end and keep it cool with water.Yes we sometimes cut some of the thicker stuff with an angle grinder Nigel. Only problem with that is you have to do it free hand and one little wobble and it's a piece ruined.

Don't you have a chop saw for wood? The tungsten tooth blade is good on the alloy a light spray with wd40 or tallow to stop the saw blade clogging up.Thanks Trev might be a cheaper option.
The majority of cuts are on thin aluminium trim either straight cuts or 45 degrees, but they do have to be accurate.
