Welding Tips and Tricks

I have a planned project coming up, a machinist work table. I am going to use 1/2" plate for the top. I want it to be as flat as possible so I'm not going to use my cutting torch. I was thinking of using a metal blade on a circular saw & starting out with the blade at 1/8", make the cut, adjust another 1/8" make another cut and so until the plate is cut. Is it safe to use a metal blade on a circular saw? Also, what is the difference between a circular saw & the one made for metal cutting like the Milwaukee or Evolution? Thanks

As long as you use a good quality saw you shouldnt have any issues.
Metal needs higher torque so gears and motor must be up for it.

I have used an evolution blade in a bosch saw many times without problems.

Just be careful with the chips. They come off really hot and sharp.

My Milwaukie 8 inch metal saw turns at 3,700 rpm, my older Milwaukee wood cutting saw turns at 5,800 rpm. Home Depot sells a Diablo blade for steel that's speed rated for 5,800 rpm. Lowes has a different brand that is slightly more expensive. I have never used either one. I figured the $299 for the metal cutting saw wasn't outrageous and the blade for a wood saw was $40 to $60. I would have no hesitation cutting 1/2" plate with the metal saw.

At those speeds you better be wearing kevlar. Personally I will stick to plasma or torches.

Check youtube for the Milwaukee metal cutting circular saw. You'd be amazed.

Hi, thanks for the info. I'm going to order one of those evolution blades & try it out.

I use one regularly in a worm drive circular saw. It will cut your 1/2" plate in one pass no problem. Ask me how I know....

Jesus lol. Didn't feel any resistance as you were cutting whatever was on top

I was dropping in on a piece of 1/4" from above. I thought it was taking a little too long but it cut right through. The key with these blades is to not hog them. If you are making significant sparks, you are pushing the blade too hard.

Wow. Just wow.
