    9" Grinder comparison

    called Makita again, they could not give me the handle thread size...voids warranty... The Makita GA9040S actually looks more comparable to the Metabo W26-230. The input watts on the GA9040S are 1,800 and the output watts are 2,600. I kind of like the W26-230 a bit more because of the great...

    9" Grinder comparison

    Are most handles for 9" grinders interchangeable between brands? can I for example take the handle from a Metabo W26-230 and use it on a Makita 9020S? I've noticed that with smaller grinders the bolt threads do vary. for example my Makita and Bosch handles are not interchangeable.

    9" Grinder comparison

    Yeah I called Makita(as well as Metabo and Norton) this morning. The Makita tech said that they don't rate their grinders by Horsepower or torque. discovered the Makita GA9040S a moment ago just before checking this thread lol How does the Makita GA9040S compare to the Metabo W24-230 and...

    Does anyone know how much horsepower or torque the Makita GA9020 has?

    9" Grinder comparison

    I believe that more specifically it states Minimum Load SpeedWhatever that means... But I agree with you in that the speed varies depending on the amount of resistance you put against the spin, probably up to the point of stopping the spin completely... I am just trying to figure out what my...

    9" Grinder comparison

    the 7" Metabo runs at higher RPM but has less torque. its No Load speed of 8,500RPM drops to a Load speed of 5,800RPM The 9" Metabo runs at a No load speed of 6,600 which drops to a Load speed of 4,500RPM

    9" Grinder comparison

    Are the rated RPMs on a grinding disk referring to the no load speed or speed under load? for example if a grinder has a no load speed of 6,600RPM and a load speed of 4,600RPM then can I use a grinding disk with a max speed of 5,000 RPM?

    8,500RPM with a 7" disk vs 6,600RPM with a 9" disk Which is better for 1/2" mild steel?

    9" Grinder comparison

    Wow thanks! Those are the W22-180's and W23-180's but they don't seem to be available in the US The W24-180(seems similar...) runs at 8,500RPM while the 9" models run at 6,600RPM Which is better for mild steel? From what I've "read" it's usually better to get the 9" since you then have the...

    9" Grinder comparison

    Thank you, this is very encouraging. The first job for this grinder will be to help me process 3,600feet of W12x26 I-beams for use as beams in a house I'm building. still have to calculate the sizing/dimensions for the 12 posts(probably something like W8x28).. Anyways, whichever grinder I use...

    9" Grinder comparison

    looks like i'm down to comparing the Metabo W24-230 vs Metabo W26-230 I have found both at significantly lower prices than list/retail. is the W26-230 worth spending $100 more than for the W24-230? they seem to be quite close in specs(page 30)...

    9" Grinder comparison

    Thanks! Great idea. If I get a 9" grinder that runs at 6,500 or 6,600 RPM, will that be compatible with the Norton Norton III grinding wheel(top speed 6,000RPM?) http://www.righttoolusa.com/p/Norton-Norzoniii-Grinding-Wheel-6-4-3-4-X-2-X-5-8-11-78173741.html?gclid=CLrKn5LBh8QCFdgOgQod11EALA...

    9" Grinder comparison

    Any attachments/guides for a Hypertherm powermax 45? I guess just using a straight edge will do the trick... Still want a powerful grinder to make great weld surfaces quickly. already have a few smaller grinders(Makita and a Bosch with speed control). the Bosch is beginning to whine
