Product Description

Amazon.com

The first thing we noticed about this grinder is just how little it is, both in dimensions and weight. But switch it on, and it does the work of the big guys. The barrel of the tool is small, so it fits beautifully in your hand, and the auxiliary handle lends great control and comfort, installed either on the right or the left. Right on top of the motor housing is the power switch; we like it there for convenience as well as safety. Despite its small size, this grinder's definitely not lacking in power, with a max no-load rpm of 11,000, and the price makes it a great choice for both the professional and the home do-it-yourselfer or hobbyist. It's an unusual size: It's half an inch smaller than the standard small grinders we're used to seeing (though it offers the same max rpm), but it doesn't really make a difference in maneuverability or working in tight spaces. Makita always goes the extra mile in quality, and here, they've sealed the motor and bearings so contaminants don't shorten the tool's life. Wheel changes are easy and fast, and vibration is surprisingly low for its rpm.--Kris Jensen-Van Heste

2.0 out of 5 stars Accessories hard to find, August 1, 2002

By A Customer

This review is from: Makita 9523NBH 4-Inch Angle Grinder (Tools & Home Improvement)

I've owned mine for about 4 years and am content with the power, performance and price. However, this grinder uses a smaller mounting shaft than the incrementally larger 4 1/2" grinders. I am finding that accessories like wire brushes and such are getting more and more scarce in store shelves. Home Depot, which sells this grinder, did not have any brushes for this tool when I recently visited. If you're only going to use grinding wheels, you can probably find them easily enough. I believe the small size of this tool also limits the maximum diameter of wheels and brushes. You can certainly save a nickel by getting this one, but unless you are on a super-tight budget, get a 4 1/2" version.

One positive on this tool: if I'm not mistaken, it is designed to be used with AC and DC power, so you can run it off of a generator.

4.0 out of 5 stars Nice tool for the money, August 24, 2000

This review is from: Makita 9523NBH 4-Inch Angle Grinder (Tools & Home Improvement)

I like to have a little more versatility in my tools but for the same price as a Skil grinder you can have the quality name of Makita.

5.0 out of 5 stars Great Grinder! But a 4.5" grinder would be better., August 20, 2007

This review is from: Makita 9523NBH 4-Inch Angle Grinder (Tools & Home Improvement)

I bought this grinder 3 years ago and it is still kicking. I use it for cutting tile, concrete backerboard, AND grinding cement areas.
As with any power tool you must be patient with them and not to overload them. When applying pressure to the unit do not let the RPMs decelerate too low otherwise the unit WILL burnout.

When I purchase my next grinder it will be a 4.5" grinder because most accessory blades do not come in this 4" size.
