Default chop saw blade life

Hi All,

I've been using the heck out of my Fein Slugger 14" chop saw, and it is already in need of a new blade.

Due to the possibility of user error, does anyone have any do's and dont's when cutting metal, that could prolong the life of the blade? I'm just cutting away with little idea if I'm doing something to shorten the blade's life.

Are you cutting with mild down pressure? If you getting a lot of smoke/dust you have too much down pressure. Blade brand also makes a difference. Better blades is longer life.

Also, what material is the blade? Is it rated for what you're cutting? Fiber or metal blade? Some are meant for ferrous/iron, some are soft metals, some are masonry. I can't usually tell the difference on the fiber blades unless I pay real close attention to the label--and I almost always grab the wrong one off the hardware store shelf when I buy replacements.

Looks like that saw is made for using metal saws. I think most people think of
14" chop saws as abrasive saws like my Milwaukee.

But either way, they are likely the most expensive way to cut metal. The
blades are not cheap and they do not last very long.

Their niche is portability so you can make a few cuts on site and finish a job
they are not the right choice for shop or production cutting.

You'd be better off with a cheap HF bandsaw for shop cutting vs. a chop saw.

And since you have a Fein you can probably afford a decent band saw.

Thanks. What I needed to hear. I have the HF and it's doing a fine job. I got the Fein because I wanted something that could cut faster and, as you mentioned, the portability aspect. So, I guess I'm over using the chop saw when I could be using the HF for the same cuts.

Yup, chop saw = abrasive blade
Drycutter = carbide tipped blade turning at a lower rpm

Yup again

I would add size/space, cleanliness, cut quality to their advantages.

I love my bandsaw but man does it take up a lot of space. I've changed the blade once in the 10 years I've had it so running costs are negligible, but if I was to charge it rent it would be a killer.

I had an evolution mitre saw way back when they were a new concept and I remember the manual had some instructions for maximising blade life which from what I've read over the years since does make a difference but I forget the specifics

That's an industrial cold saw. Usually runs HSS blades, maybe 80-100 rpm max for steel, faster for non-ferrous.

I have a drycut chopsaw. Your Fein looks exactly like my saw from Princess Auto.

Blades are around $160. There are ways to get long life out of the blade.
1. know for a fucking fact that you are cutting mild steel only. A band saw will cut tougher alloys with no harm.
2. fasten the steel securely in the vise.
3. do not try to cut anything too short, that could roll or move in the vise.
4. if you have ignored the above and killed a couple of teeth, pull the blade and have them replaced in a saw shop. Well worth it for 5.25 a tooth.
5. And never let some idiot hanging around the shop try to use it.

Also use a good quality blade. I use a 14" metal Devil with 60-70 teeth, or a Tenryu blade with same specs. They last the longest. I now get about 6 months out of a blade before I need a tooth or resharpen.

They will cut fast and last a long time if you are careful. I always have a spare blade so I never have to stop what I'm doing, and don't make " just one more" cut if a tooth is K.O'ed
