Thread: Better than Sliced Bread

Yes always wear eye protection... A 4am dash to the hospital yesterday reminded me of that (after 7 hours of lying in bed as I could not shut one eye), although the stuff I had in my eye got there after rubbing my eye with my hands (that had fine cast iron dust on them) not actual grinding or machining..

I agree - I use the 1mm thin discs designated for stainless to cut all sorts of metal...they work absolute wonders.

The only apparent negative is that the thin blades have no tolerance for being out of alignment.

You have to start straight and finish that way otherwise the blades snap easily.
Given the high rpm the angle grinder spins at there is a potential for thin broken sections to be ejected at high speed.
We have been using them at the school and find that a suitable technique is to grind a straight groove in the surface of the item to be cut.The blade then follows the path of least resistance and is more likely to stray off the straight line and possibly shatter.
This is course is fairly limited to thin walled applications.

All I can say is that " I LUV EM "
All my grinders now run stainless thin kerf wheel for cutting.

I started using the Flexovit wheels which were OK, then saw some really cheap deals which looked good. I could rarely get a full cut out of them - wearing them down to the hub in minutes. Then I found the Hitachi ones, I'd swear they were indestructible, they'd have to be for the price, but worth every cent!

Hoes the price comparison of the Hitachi discs against the others .
I paid $2.97 for the 125mm discs a while back .I think they were flexavit brand.

Apparently the eye heals so fast that you have less than 24 hours to get the shaving out before the surgeon will have to dig the splinter out. Also there are plenty of people with red rust spots in their vision from angle grinder use without glasses.
