    Replacement 100mm angle grinder ?

    I have a number of 100mm angle grinders, one with a cutting disc, one with a grinding disc and one with a big wire brush (there is also a 125mm and a huge Wolf grinder which kicks a bit on startup !).

    Anyway, my favourite which is currently abused with a big wire brush fitted for removing rust from hubs, axle casings etc. is starting to fail.
    At the weekend, after a short spell of vibration, it lost all drive. Turned out that the screws holding the guard also hold the front of the gearbox in place and had come loose. Tightened them and it was working again but it is getting noisy.
    I purchased it in the UK at least 30years ago and it's had a hard life. Used for grinding & cutting then in more recent times it's been used for wire brushing It's a Black & Decker (Made by Black & Decker Italy) and only 450W. Probably out of warranty by now so I need a replacement.

    The question is do I buy a name brand or a cheapy to replace it ?
    My 125mm is an Ozito cheapy and the rubber cord protector where the cable exits the handle broke after a few uses over maybe 2 years. The B&D cord protector is still intact ! Do big names mean a better quality ? Will I be able to find one to last as long as the old B&D ?

    I'll run the B&D till it fails but I will need another soon......

    1. Virtually every new power tool is now made in China, make of that what you will.

    2. Lots of people buy cheapies from Bunnings etc and are happy with them, just don't expect any spare parts to be available for them when they break.

    3. I am now a 100% Dewalt user, I think they are great performers. A new one:

    DeWalt Angle Grinder with Toggle Switch 800W 100mm 4" Power Corded DWE4001-XE | eBay

    And a hardly used one.

    DEWALT DWE4001-XE 100mm (4") ANGLE GRINDER - 800W | eBay

    The last grinder I bought was over 20 years ago - a Hitachi, which is still going strong. No idea where these are made now - I guess China as is everything else so not sure what the quality of those is now.

    I have a similar issue with a cordless drill at the moment - my 18 year old used and abused daily Snap On has **** the speed controller so it only goes flat out now, and doesn't brake when you release the trigger. Still wondering what to replace that with. Tried a DeWalt that a friend had but that didn't have a brake in it either, so pretty useless for what I need unless these is a model that does that - it certainly had no issues drilling some 1/2" holes in 6mm steel.

    There seems to be a lot of love out there for DeWalt so I guess it must be pretty decent overall.

    I just buy the cheapies nowadays. The last $20 4” grinder I bought lasted five years. I then bought 3 $25 XU1 4” grinders from Bunnings, cutter, grinder, and flap wheel. Still going after two years with plenty of work. Worth having the extras just to save time swapping around blades. If need be you can find cheap carbon brushes on eBay to fit anything to keep them going.

    I got given an XU1 cordless drill - it lasted 1/2 day - 2 charges of the battery. Had some decent GMC stuff - mostly woodworking stuff which I only use infrequently so that's probably why. I killed dads cheapy grinder in one use too, so depends how much you expect from them. My 125mm Hitachi gets to cut up 1/2" plate and other such stuff - stalled it more times than I can remember, had smoke coming out of it and it still going strong. Would like to see that from a cheapy.

    Bunnings

    Buy it (whatever) from Bunnings, (no, I don't have shares), 2 or 3 years replacement warranty. Even for cheap as chips models.

    Regards

    Hehe i have an aldi 1000W grinder with a variable spped that goes up to 7!(??).

    I dont fabricate much metal stuff but it seems to go ok.

    If its for wire brushing stuff on the car maybe a battery powered one might be the go for the comvenience factor.

    A few builders i know use the ozito stuff due to the warranty (1yr commercial and 3yrs private). They just replace them if anything goes wrong, so if you abuse it and it breaks in 3 years go get a new one. Its no good if it dies during something important though...

    In my line of work, and the sites I visit, it's not uncommon to see a pile of dead grinders on the workshop floor. Foundaries are the worst for it.
    Anything from the cheapies, up to hitachi, metabo, fein... they all die the same. I cut the middle and got a cheap model from a good brand- a little chinese metabo 4" 800W job. Suits me fine for what I need it for.
    If you are a home gamer, go cheaper. Most of the cheapies these days will die before you need to get brushes or bearings for it, and even the primo ones have that much design obsolescence in them that spares will be hard to come by.
    Most of the big manufacturers have Chinese made, and home country made products at different price points. Metabo for example have Chinese stuff, and their high end German stuff.

    The XRP models with the 3 speed gearbox certainly stop the instant you release the trigger. And with my big hands I can do some serious damage with one of them. Cranked over a VW 1200 Beetle engine with one.

    Just about all of the power tools I get for work are Makita and they cop a flogging all day everyday. The Makita 100mm angle grinder is only about $90-100. It's what I bought for home also, except in 125mm.
    Cheers
