To add to and re-emphasis the importance of safety when using angle
grinders, especially when working alone (there isn't anyone to run one to
the hospital in case of mishap.)
I gave myself a pretty good gash one time with one of those 4 1/2 inch
grinders. Didn't bleed to death but thought I was going to at the time. I've
also had a disk on a 71/2 inche Milwakee explode on me when grinding on a
piece. The FACE SHIELD, did I mention that I was wearing a FULL LENGTH FACE
SHIELD, by the way the Face Shield that I was wearing saved my eyes.
If I haven't been clear let me reiterate that it is just plain dumb,
foolish, ignorant and otherwise lacking in any form of consideration for the
well being of oneself to not wear a faceshield every time an angle grinder
or dremel tool is used.

> Dear all. When using a grinder, please remember that the RPM, Rounds Per
Minute is at least 5000 RPM and many time much higher. The grinder cuts by
speed of the wheel and the grit surface. That means a heck of a lot of
"energy", much more than the rated horsepower. If it is a small dremal tool,
the possible 'kick' will not generally be hard to handle, maybe a cut finger
or a gouge. but when using any grinder bigger, unless you are really

a welder, grinder, auto body repair and so on, I have seen my professionals
really get hurt by one "little 4- or 6- inch angle grinder ( a 4" grinder is
usually traveling about 5,000+ feet per minute at the grinding edge, with 6
inches much faster). In addition, if you take "chunk" out, it usually
requires plastic surgery. I know because that happened to me when a

my fingers off. Took some plastic surgery to put is all back together. I was
lucky as another worker was able to take me to the emergency room, then six
hours sin surgery and months of healing. Another buddy I worked with
"ground" through his leg, cutting a muscle and a artery and limps to this

a mask, wear goggles, wear leather gloves, wer a leather or camvas apron, no
loose clothing or hair. Best to be done outside as you can never get

SOME INSTRUCTION/HELP IF NEEDED. ALSO HAVE SOMEONE AROUND JUST IN CASE. WE

ALWAYS concentrate on the job in hand. I was cutting up a large metal brick
makers trolley, and I forgot that it was not my small 6" one (easy for me to
cope one-handed although not to be recommended), I took my mind off the job
in hand and the bloody thing kicked back and smacked me under the chin,
knocked me over and added a further 8 stitches to my count of many.
