Milwaukee 6148-6 4-1/2-Inch Magnum Sander/Grinder

by Milwaukee

Product Description

The 4-1/2in. 5.5 amp grinder is ideal for getting into tight spaces where other grinders can not. Its low profile and light weight make it perfect for those lighter duty sanding and grinding projects. The tool is double insulated (two prong cord) and incorporates the industry standard 5/8-11 threaded arbor. Like its heavy duty big brothers, it also has spiral bevel gears for optimum transmission of torque to the work piece. The comfortable body grip style is easy to hold onto, and in conjunction with the supplied side handle, allows for maximum operator control. The wheel guard can be moved around the spindle (without the use of tools) for greatest operator protection. Sold as a grinder with guard, this tool can be used as a sander. U.S.A.

5.0 out of 5 stars Milwaukee Rocks...OK, it Grinds, March 17, 2000

This review is from: Milwaukee 6148-6 4-1/2-Inch Magnum Sander/Grinder (Tools & Home Improvement)

I used my 6148-6 sander grinder with a wire brush to clean rust off a mower deck. The tool had plenty of power. Two features that I particularly liked (besides the power): the three position extra handle. At one point, it was too awkward to get at the deck with the handle to either side, but being able to work with it atop of the grinder, was great. Second, the safety paddle switch was a real plus. Having used another grinder without the switch, I used to worry about dropping the tool and have it continue to operate. The Milwaukee paddle/safety was unobtrusive and effective. Great tool. Don't forget your eye, ear and respiratory protection.

5.0 out of 5 stars Excellent Grinder/Cutter!, August 3, 2004

This review is from: Milwaukee 6148-6 4-1/2-Inch Magnum Sander/Grinder (Tools & Home Improvement)

I built a fireplace in my basement and needed a grinder/cutter to shape the stones as I put them on the fireplace. This tool worked great. With a diamond blade it cut the stones like butter and the grinder wheel fine tuned the stones so they fit perfectly. The three position handle was especially convenient in the shaping and cutting the stones when I found myself in an awkward position. The motor had plenty of power and didn't bog down. Removing and installing the blade guard was a little awkward until I got the hang of it. One of the previous reviewers complained about the wrench and how difficult it was to use. I found it easy to use and had no trouble changing blades and wheels. I highly recommend this tool.

5.0 out of 5 stars Durable powerhouse, September 4, 2006

Stingersplace "Stinger" (Louisiana) - See all my reviews

This review is from: Milwaukee 6148-6 4-1/2-Inch Magnum Sander/Grinder (Tools & Home Improvement)

I bought this grinder more than a year ago and have used it weekly with periods of daily use. It is an 8.5 amp, 10K rpm single speed machine and one of my favorite tools. I'll admit it. I don't treat it nicely. The guard was set aside the first day I used it. I now generally keep a 5" grinding wheel on it and it does eat them quite voraciously but that's its job. I also have a third party sanding back (from Home Depot) that is nice for finishing metal or roughing wood. I've also used the flap sanding wheels but they are a bit pricey. I like the spindle lock on it because you can reach it with your thumb, thus allowing the replacement of wheels without tools for some people.

The only time that it has ever failed me was my fault for putting it in the vise (by the body). It refused to turn on. When I took the case off to see what was wrong I noticed that I had pinched the cable connecting the brush to the motor and it had jammed the brush. A quick flick and the brush popped back in its place and all has been well since.

I have had it running for as long as 4 hours straight and it just continues to run without complaint. The lock on the switch is plastic and is starting to show a tiny bit of wear but it still works so I'm not complaining. I've ground down hundreds of ugly welds, sharpened a lot of drill bits and chainsaw blades, and cut off a lot of heavy steel bars, bolts etc. I've never stalled it, it has scads of power.

Basically, I've given it a good workout and it is still going strong. Enough said.
