HAWK needs help.

[Wheat]

I'll try by best to respond to your question Hawk. Went to the LWS, saw my buddy there. Told him what I was doing and needed for aluminum. He recommended the Rex-Cut type-27 wheel. Said he's been selling them alot lately to the trade industry. I use the the wheel for dedicated aluminum use only. Not to sure what you mean by "sigma" No real other idenification markings to assist....HTH.....

Hawk,

After reading your post I went to the Rex-Cut site (link posted above by burninbriar)and ordered some of the Sigma-Green wheels for both steel and aluminum. Thanks for the great tip on a "new to me" product!

Great Stuff!

Bob,

I know they are expensive by regular grinding wheel standards, but very much worth it. I used a 7" Sigma Green wheel this evening that is pretty much worn out from grinding on AR400 and 110-18 welds both wet and dry. The wheel is basically slick. I used it to cut out several spray arc 5/8" rebar where I had missed a couple of measurements. It just zipped right on through them!

Hawk,

Thanks for the report. It's great to find good products that can make a project go much faster! I'll never have to use them the way that you do but if I do have to grind, I don't want it to take forever.

Where to buy Rex-Cut Sigma products

Where is the best place to purchase a some Sigma grinding wheels to try. None of my local supply houses carry them and want me to order a whole case. Is it best just to order from the manufactures website or is there an internet dealer that has better prices.

BTW, I purchased a 7" anti-vibration Bosch grinder and love it. I can grind for 3 or 4 hours at a time and still feel my hands.

I purchased some to try right from the manufacturer site. They really seem to cut well and last longer than standard grinding wheels.
