    Cutoff wheels...1/16" or 0.045"?

    I've been using a lot of 1/16" thick, 4 1/2" cutoff wheels lately. Most of the cutting with the 1/16" cutoffs has been on 1/8" up to 1" mild steel (A36) bar and rod, plus some sheet from 1/8" up to 3/8".

    It seems that the 1/16" cutoffs are becoming fewer in stock at lot's of places and the thinner 0.045" cutoffs are becoming more common. Have any of you found the thinner 0.045" to be as durable and why does is seem that more of them are being used?

    Some say the thinner 0.045" wheels have to cut less metal, therefore are quicker to cut than the 1/16" (0.0625"). It's hard for me to believe that 2/100's of an inch would make a lot of difference. I personally would think the thinner cutoffs would be somewhat more dangerous at the high RPM's of an angle grinder.

    For me anyway, I've always liked the thinnerwheels as they do seem to cut faster. Especially on stainless, they seem to zip through like butter without a lot of heat buildup.

    Using 1/16" disk you cut 38% more material than 0.045". I preter the last one

    Is it safe to cut stainless with an abrasive wheel?

    with cut-off wheels thinner is better. as for cutting stainless, my chop saw was on another job and i try not to cut stainless on the band saw so i broke out the cutoff wheel to cut some 2x1/8" flats for a security frame with no problems.

    Never had an issue with it. And thanks to all the low dollar shops, and abundance of field work,we use abrasive wheels exclusively at work. The wheels we use are marked as steel/stainless

    Looks like no one is having problems with the 0.045" cutoffs. My main concern was with them possibly breaking easier than the 1/16" ones. Of course with the thin cutoffs, you can't go "King Kong" with them.

    Chrisn, there are cutoff wheels labeled for use with stainless, as dcoffmanjr mentioned above.

    I like the thin cut-offs less heat and alot easyer on your tools.

    Builds up a little more heat but never had a problem.

    Thinner ones are easier to break. With any of them it is important to maintain the same angle throughout the cut so as to not introduce any side force or binding.

    welding, plasma cutting and grinding chromium alloys can produce chromium six. A mask and good ventilation is recommended.

    I don't cut long straights often. If I have to cut a long piece of sheet I'll snap or draw a line and make several shorter cuts. It isn't perfect but it is much safer than binding a blade and snap... OUCH!

    .045 is the way to go Walter, Flexovit razor blades or Norton stainless cutting wheels followed by Metabo super slicers.

    Re: Cutoff wheels...1/16" or 0.045"?

    Usually when I cut bar or small dimension plate, I use the white paint markers. It makes a line that is just a wee bit wider than a 1/16" wheel, so as I cut, I can get a glimpse of white on both sides of the cut to stay on track. For long cuts, I usually make a shallow scoring line first, then follow up with a deeper cut. Seems to help the wheel follow the path it's supposed to. The white is also easier to see in the shade.

    I got by accident some 14" 3/16. That was awful, it takes a lot of horsepower to drive a blade that wide. I've not seen .045

    I think the thinnest 14 inch wheels you can get are 3-32 inch thick.

    The 1/16" and 0.045" I was referring to was for 4 1/2" angle grinders, not 14" chopsaws. A 0.045" in a chopsaw would probably explode.

    Yes I run 4 1/2 angle grinders.

    Re: Cutoff wheels...1/16" or 0.045"?

    Here at our shop in the winery business we use Walter mainly and they are by far the best for us. We have used Norton,Standard Abrasive, Radnor,Weiler and Gold by carborundum abrasives. The Walters seem to hold up the best and have the best results on SS and Aluminum. You pay a little more for them but get longer life out of them as well. So they are good enough for me at work so use the same brand at home for my small business. Walter makes great Chop saw blades as we use those as well and a lot of their sanding disks as well. Im not just saying Walter is the best , but they have shown how well they hold up to the hard abuse of SS and I cut, grind and weld it daily here at work. Them some at home as well.
    As for grinding on Steel the Standard Abrasives stuff holds up pretty good and half the price as the Walters so we tend to use them for our little bit of steel use.

    I haven't seen any Walter cutoff wheels in the stores, but have seen them online. I am not familiar with them, but sounds like they are worth a spin (pun intended .

    Probably will order some and try them out. Thanks.
