Review on BHA Metal and Stainless Steel Thin Cut Off Wheels for Angle Grinders, 4 inch x .040 inch x 5/8 inch - Pack of 25 by Robert Hole

I have been using pneumatic and electric grinders for over 39 years and have used many different types of grinding wheels from grinders to power cutters and these wheels have held up very well, Anybody With a little familiarity with large cut-off wheels, I know that it's important to make sure the wheel is centered on the hub of the grinder, which prevents vibration from an off-center wheel. I use a Milwaukee grinder and these discs fit the hub perfectly. The cutting disc will fail prematurely if you use force instead of letting the disc do the work, or use the disc as a grinding disc and use the outside or inside of the disc, causing the disc to fall apart! These wheels are very well preformed
