Broke down and bought a metal chop saw.
Permalink  

After 20 years of cutting project metal with a 6" zip wheel on a medium angle grinder ...I'm done with it. Binding, broken wheels, sparks and dust in the face. Not safe at all, but I've been lucky.

So I bought a Skill Saw 14" Friction cut off saw. Not the cheapest, but not so expensive either. Seems to feel pretty sturdy. We used this type of saw at the mill and beat the crap out of them. They'd die, and right in the dumpster they'd go.

You know, I was flopping back and forth between friction and the new carbide cold saws. But you know what, I've decided I'd rather deal with some dust, sparks and a new wheel every so often rather than deal with metal chips. Disks are about $25.

Yea, I can't stand little sharp cuttings. No matter what, I always will end up with one in the foot. And apparently they go absolutely everywhere with the cold saws.

 

Thoughts?

Thoughts? Just one. I'm jealous. I've been contemplating one of those for a long time as well.

I bought a used band saw last year but there are times where the chop saw would be ideal (like about an hour ago when I was cutting angle iron with a band saw, which sucks...)

Congratulations, I'll be waiting to hear how you like it.

14 inch is a great choice, how many amps is the motor? Work would buy them with low amp motors, very easy to stall out

15amps.

Should be fine for lighter project material. Thickness will rarely be more than 3/8 or so. The trick is a good disc and the correct pressure.

I remember as youd get past half life of the disc they seem to lose their oomph. Maybe its an excess rpm thing? Youd end up with lots of sparks but no progress.

 Don't you find the little cutoff wheels on the diegrinder are the same way? Once they are down to about 1/2 they don't work worth crap.

I have had a Princess Auto Chop saw for probably ten years. It was also rated for 15 amps but I found it trips a 15 amp breaker easily sometimes on startup. I also have a couple of 110 volt 20 amp plugs for my mig welder so I usually plug the saw into the 20 amp and dont have any problems with it.

Maybe at that point it runs out of abrasive? Ends up with more resin?

Id originally thought that maybe you could fit a carbide blade into a friction saw, but the frictions high rpm (3200?) makes that a no no. The carbide blades are limited to 1500 or they overheat or throw a tooth.

 it would be nice if they had a soft start. Perhaps the pricey ones do?

 The newer ones may be using soft start technology. My saw is about 15 years old and still works well. The starting current spike of a 15 amp motor will easily trip a 15 amp breaker. Of course the saw was on sale (cheap) when I bought it. Price was definitely the determining factor.
