Sawing Metal

Another possibility is to use a cut-off saw with a Steel Demon blade. I have an old battery-operated Makita 7.25" saw that I use to cut just about anything - within its range of course. I have cut 2" square tubing for a 2" x 72" grinder I am building. Takes about 25 seconds to make one cut using this saw. It's pretty amazing. I had an old Grizzly bandsaw and that was taking over 3 minutes to make a similar cut.

And the dry cut saw will do it in 5-10 seconds :) Having the right saw for the job makes a world of difference.

Oh, and I agree, bandsaws are generally slow.

Can't be slower than a hacksaw.......
lol I mean, depends on the hacksaw :D

Have any of you guys used a inverted jigsaw.
Rockwell makes a BladeRunner that looks interesting for small shops with a variety of cutting required.
Just looking for some first hand experiences.

Kinda like a scroll saw but without blade support on both sides?

They say it can handle some metal cutting, but it seems to be a light weight hobby saw for wood. I am guessing Aluminum would be the only metal it would cut.

Never use an inverted one, but my Bosch top handle jigsaw has probably cut 10x more metal than wood in it's lifetime. Works really well for sheetmetal too, and sometime I prefer it to plasma.

Are you talking about bar and plate . . . or just sheetmetal ?

Mostly sheet, but lots of angle and tubing too. It's chewed through some aluminum plate (1/4"-1/2") a time or two as well. Even some 1" tooling plate. I used to keep it in my box at work, but took it home as I always needed it more there. Nothing worse than needing a tool at home you have at work, or the other way around.

If I didn't have a horizontal bandsaw I'd still use it for 45* mitering of angle (ex 2x2x1/8"). Really quick, and imo way better than a portaband, or angle grinder. Super easy to follow layout lines, and get a nice fitting joint.

Variable speed is what makes it so versatile. And good blades are necessary.

For a good while it was my only metal cutting tool besides a recip saw, and angle grinder at home. I don't use it much anymore because I have better options, but I should bust it out more as it IS pretty handy to have around. Portaband tends to be the go to because it hangs on a hook next to the vise. Even if it isn't always the best tool for the job.

EDIT: one of the best reasons I liked it so much is that it was quiet. I hate air tools, and loud angle grinders etc. I'd rather take a bit longer, than listen to that racket. It's also pretty clean too. Chips just fall to the floor, and don't get flung around the shop all over the place. I used a wax stick lubricant on the blades too.

I never considered using my jigsaw on metal. What blades do you prefer?
I just buy home centre blades. they are cheap, expendable, and reach inside enclosed circles when I need them. For heavier cuts I use the reciprocating saws-all type saw with a metal blade - it works well enough when I have to cut stuff outdoors.

I was fortunate enough to get a pretty large quantity of Starrett bimetal blades in an auction lot many years ago for pennies on the dollar, but have used bosch blades as well. Maybe others? Slow speed will make your blades last exponentially longer, thats where the variable speed comes into play and is pretty essential. It's just another cutting tool where proper speeds and feeds are vital to it's survival.

I like the JIG SAW for cut-off purposes.
- Little heat buildup
- No sparks
- Small blade cost (Use the HSS blades for metal)
As @DanDubeau says, variable speed control is a ‘must’ option.

Another vote for the Bosch jigsaw. I’ve cut up to ¼” steel bar with it. I’ve also used it for cutting propane cylinders as there’s no sparks.
It cuts thin aluminum almost as easy as it does wood. The Bosch blades are far superior to the regular Home Depot type blades.

I’ve used my Bosch jigsaw on aluminium, I’m reluctant to try it on steel as it’s primarily a woodworking tool.

I’m suspecting I should try it before I commit to a portaband saw.
