Cheap 3" mini grinders

[MattF]

I wonder if the batteries will fit anything else?

Neither Parkside nor Bosch.

Bought one of these a few weeks ago and have had no issues with it so far. Battery lasts longer than I thought it would and have cut through 1/2” bar no problem. Can’t complain for the price. Must be the luck of the draw.

Since I've had my partial refund, every time I try it, it works. I haven't tried to do any work with it though, so I'll have to take it back to the shed and try it.

Same here, I've cut small bolts down, metal & plastic pipe and wood frames. So far so good.

It's so tame, horses for courses and all that, has zero kick on start, lends itself to doing smaller things with more accuracy and control and hardly any noise. Have 6 other various grinders but this is my current go to for piddly stuff

Nor Milwaukee.

Tried mine today, chopped some big head fasteners too length fine, went too cut down the 10mm stubs that go on them and dead, it starts but cuts out.... bah i'll see if i can get a refund for them, i bought one for a mate for his xmas....he has the bag with it in !

I've reset the video too unlisted... available shortly

See #111 & 114 @jsf55
Had not torn it down to see where the problem is. I think it is a battery fault rather than the SW/motor side of things
But both the batteries I have do the same run off load OK very light cut run for 5/10 seconds.
Have just run a test, 2 jumper wires to battery.
Light cut almost resting on 3mm sheet lasted first cut 8mm deep from edge aprox 10/12 seconds into sheet battery cuts out 0V
Second cut 5mm 4/5Sec. cut out battery volts 0V
Third cut 1.5mm 2/3 Sec. cut out battery 0V
So mine is a battery problem thermal cut out ?? the charging port is in the battery so only the motor A diode and switch in the main body. Can I be bovvered to hunt problem down.
Battery does come apart without damage

 

[jsf55]

I thought thermal overload, but left too cool for sometime and it cut out no load, worse still no disc on and it still curt out ...bah, i'm over the 30 days too

Once mine starts, it seems to be able to run for quite some time. When it's decided to not start, it just turns a small amount, a quick flash from the battery indicator, then stops. I have no electronics knowledge so unfortunately can't contribute to the search for a solution. I'd really like to hear if there is one, particularly if it's relatively minor, as I accepted a partial refund so I'm pretty much stuck with it now. But, if discs are an issue (I was under the impression it'd take the same 75mm discs I use in my air cut-off tool, and maybe that's not the case, and I didn't check before buying) then it's not going to be much use soon anyway, and when I accepted the partial refund I was effectively accepting I've paid ~£13 for a paperweight. Should have stuck to my guns. Oh well, no use stressing over it.

Refused a refund, i wonder if i can get it further with PayPal

I have a couple of parkside versions of these small cut off saws.

But really I prefer my reversible composite body air die grinder to these battery versions.

Being reversible to control the spark direction, high RPM and good torque make the air cut off tool my go to choice. Albeit I have air reels and very good air storage etc.

It should.

I think that was their first response to me, sort of "try harder, I'm sure it works if you switch it on properly". Then we got to a 30% discount and as it was working sometimes, I thought I'd live with it. Others have had the same, but persevered and got a refund. I think I mentioned that if I don't get one, I'll just raise an issue with eBay and let them sort it out.

But really I prefer my reversible composite body air die grinder to these battery versions.

I have various air things too, but I don't always have the compressor on so they don't get as much use. This seemed as if it would be really convenient, another option in terms of different shape to get into awkward places.

 

[droopsnoot]

It should.

I didn't try it, but there were some comments earlier about making adapters and not being able to find discs. I haven't read them in detail, but hopefully I just read them wrongly. Still, doesn't matter at the moment.

They are handy to have yes. I found the 12v version stalls too easily and not much power. A 20V version is more usable. I do use them say if had a one off bolt to cut something like that. Any larger tasks and the air one comes out.

I imagine though that brushless versions would be alot more usable too so would be worth the extra £.

I messed about with mine this afternoon, i checked the batteries, one was 11.3v the other was 12v but i decided too try the Milwaukee one first with some 'jump leads' it ran fine no issue, so i put the 12v one in and it run ok, put a cut off of stainless in the vice and butchered it with the grinder, bottom of pic, all good except for a rather warm 47c battery, so maybe it's just one duff or flat battery that had little use
Put the battery on charge but after 90 mins the ked was still red and it was tea time

I'll look at it later

Big Clive has done a review today:

Good little strip down, good to know.
My yellow one does not have the battery level indicator.
Still refuses to fail but good to know about the batteries!

 

[jsf55]

I wonder if i can get another better set of batteries for mine or just heat them up !
