Assuming you were cutting a piece of 1/8"x1 1/2" flat bar in a chop saw with it laying flat in the vise. Which is the best way to cut it? With the blade contacting the front (part closest to you) of the material first, the center of the flat bar or the rear of the flat bar? Thanks......

The best way to cut flat bar with an abrasive chop saw is with the bar in a vertical position. The smaller the section the blade encounters, the more efficently it cuts.

linc, I went out and tried it after I read your post. One thing for sure - it doesn't get as hot! Maybe that's the way to go. Thanks for the reply..Comment

Do NOT cut flat bar verticaly. After the abrasive blade gets hot, you will NOT get square cuts.
As far as where to start the cut, first off, I've never used a chop saw that was adjustable that way, and second, I really don't think it matters. If it cuts, it cuts.Comment

Sorry, Mike I have to disagree with you...I always cut flat bar vertical. If the blade doesn't give you a straight cut, the problem is in the blade, or the saw, or both. I have a makita that cuts perfect every time and its' 15 years old. i also have a Dewalt 871 that is new, and I have never had a decent cut on it. (see my previous post on it). I have used HF blades and have had good luck with them. The Dewalt blades do bend, and IMHO are too dangerous to use.

Glad to see you back, Rocky....I tried one vertically last night and it doesn't get nearly as hot as cutting across the flat. As for straightness, it was as straight I guess but I do know that the blade flexes. It's a DeWalt blade. Are you saying that the blades from HF are better? If not, in your opinion, what blades do you suggest using?Comment

The HF blades are slightly thicker and stand up well. Cutting flatbar laying down can lock up the blade due to the heat build up. It's a good way to break a blade. I know...I've done it.Originally posted by Mowjunk

Good deal, Rocky....That's what I needed to know. I still like those dogs you raise. One day.......maybe in the not too distance future, when I retire and have more time to spend with it, I might look you up for one of those pups. In the meantime, I have Mr. Heinz57...lol.
Thanks to all who replied. It's good to have information like this basically at our finger tips.Comment
