    Default a grinder is a grinder, right???

    at my work, we use dewalt 4 1/2 inch grinders, they burn up pretty good too. most of the stuff i make there is aluminum and weld it, then grind it flat and smooth. for some reason not even the13 amp one has held up very well to constant hard flap wheel use. at home i use a 12 amp milwuake, and a "green, no namer" i use it for trash jobs. but the milwuake doesnt get nearly as hot. they will not purchase milwuake tools at the plant for some reason. maybe something to do with the distributor. the lws carries dewalt, so no help there. i have heard of metabo, does anyone know if they are as good as they claim them to be??

    you must be really hard on your grinders
    the dewalt gets a prity good reputation on here, as dose the millwaukie and the metabow seems to be the one of choice for thouse that have the $$ to invest in it. byt the other 2 are top choices.
    thanks for the help

    Default dewalt grinders

    At the fab shop I work in there are approximately 40 of the 4-1/2" grinders in service. WE send in approx imately 2 a month for repair...and replace probably 2 a year...paying higher prices for other brands has not seemed to justify changing brands for better quality...we tried some Ryobi, MIlwaukee, and Makita and all failed the first time past a rebuild point.

    While all were decent none were spectacular. I hate to say it but I view them as a relatively expensive consumable and in the end it comes down more to personal preference than hard and fast...this is better data.

    Good luck...use what you like and don't beat your self silly making a decision.

    I just did some research on 4.5" grinders. As far as cost goes Metabo is right in line for $$$. The milwaukee is the most expensive when comparing the same AMPS. and same featured units. Dewalt is a Black & Decker product, and one of the least expensive besides ryobi. In tests Dewalts ran the hotests under load. Ryobi outlasted the Dewalts and B&D's. Milwaukee is a very good unit less heat and ISO 9001 . Bosch, Metabo and Ryobi had very good performance, except for the ryobi switch. Best bang for the buck was Bosch when comparing 8-10 amp Grinders. Makitas were also rated well but inconsistent issues with brushes,switch and gear cases. Plus old school ergos on the makitas. Bosch and Milwaukee best warranty, but milwaukee had some preventitive maintaince in order to keep up warrranty. Which seemed like a hassle. I personally chose the bosch, then metabo and then ryobi according to reseach and the 2 local authorized repair centers for all of these units. Ryobi is definately a consumable when considering its 29-39 dollars for the 8.5 amp version, cheaper to buy new than repair. 10 amp metabo 75-85.00, milwaukees only good unit is the big 12 amper at 99-110.00 , variable speed version 159.00, bosch 8.5amper 69-79.00, dewalt 10 amp 59.00. dewalt 12 amp 75-80.00 and the largest dewalt 4.5 " 119.00.
    Keep in mind toolless wheel change option, stay away from variable speed unless its used in conjunction with a positive on off switch. Those usually burn up, especially when working off genertors and gens with load sensing pulse. small size for tight spots like makita,ryobi,bosch and metabo, rest are bulky and heavy. Look for lock on switch capability, toolless guard adjustment, (milwaukees seemed to be best) not sure of how durable it will be. Bosch and metabo have anit vibration handles too. good luck hope this helps.

    I use Metabo, work great. Also have the older Balck and Decker "professional" series which were pretty good too. Seems the 4 1/2" grinders take a beaten because I think we use them for jobs bigger than they were made for Lets see, i've ruined a Craftsman, Makita and although I love Milwaukee power tools, I used one of them up too. So far the Metabos still going, One is only about a year old the other is 3-4 yrs old.

    good luck, you'll proabably change your mind on brands a dozen times over the years. As in most things you get what you pay for, so don't pick a cheap one.
