Regardless of the specific use to which an angle grinder would be put are
there any general characteristics you would recommend that would be worth
I know that that is rather vague but an angle grinder is not something that
would get used too often so it is hard to give specific uses. But I guess
that there are some common characteristics to help explain the wide variance
I have a cheapo 9" grinder. The only drawback I am aware of is that it
is exceedingly heavy. I've never used a good one, so I can't be sure
that's the only difference in practice. However, hefting them in the
shop, the cheap ones are double the weight.
For occasional use, look at the Aldi/Lidl special offers. For more
regular use, look at buying Makita or a similar well known brand name.
I have four or five Aldi type ones, each with different blades. all
115mm except one of 125mm. 115mm disks are cheaper, the grinder lighter
and easier to get into tight spots.
A cheap green Bosch 4.5" is a good general purpose tool for slashing
bits of metal. It's the tool of choice for buggering about with cars and
small scale masonry work.
However, if you need to chop concrete on a regular basis, you'll need a
Well if unsure of the use, then its safest to assume cutting masonry
will be a likely task. That really suggests that one with good bearing
ans switch sealing against dust, and adequately protected armature windings.
Since even top name grinders are not expensive, I would suggest going
with one of those.
You have not specified the size of machine you are looking at, but for
general purpose use one can probably assume 4.5". For masonry work a 9"
is more useful.
Something with an "industrial" rating will designed for continuous use -
this is worth having as I have seen many people burn out cheap grinders
simply by using them for 20 mins.
I got a Bosch 115 model. Very nice soft start. Happily get the same
model again were I to need to. From memory, it was a very reasonable
price as it was not bottom of the range. Came in a very serviceable
plastic case with enough room for quite a lot of discs.
I have a cheapo that I bought maybe 10 years ago, not sure what I bought
it for but has had ocassional use along the way, this and last summer I
have used it to cut through 3 x 2 paving slabs probably about 30 in
total. Its only a 4.5 inch so I get about halfway through and then thump
with a hammer. Its noisy its heavy but not used a lot. I only do a few
paving slabs at a time so it works for me.
