Customer Questions & Answers

I don't see an attachment that allows using a cut off wheel with this. I only see the package of grinding stones.

There's no mention of any Husky attachment piece (arbor?) to secure a cutting wheel to this and I didn't see anything when I was at HD to allow me to use a cutting wheel. Does HD sell such a device and why isn't it listed as a necessary accessory?
Asked by: LeoH
Granted, I am new to the whole air tool thing, but I was looking for a small cutting device to remove bolt heads and the fact that the page shows cutting discs, as well as grinding stones, often sold with this device led me to believe it would operate a cutting disc as it was, or at least, with an added cutting guard. I find that grouping confusing if you're not knowledgeable about this tool and its purpose.

Can you use a cut off wheel with this tool?

Asked by: Brady
Yes. You'll need to pick up a cheap mandrel, but I use 3" cutoff wheels on a regular basis.

Where is this tool manufactured?

Asked by: CC
This is a high quality professional quality tool that's manufactured in Taiwan. This grinder features reduced noise, higher torque output and a precision collet for more centricity and "Lower Run out". Most grinders in the retail market are manufactured in China, are noisy, feature cheap bearings so the operation is not smooth or precise. On top of that, Husky also offers the longest warranty in the market with 2 years.

Rated 5 out of 5 by from Great product that works very well. This die grinder is a perfect fit in my hand. Most others are too small and weak on power. This one has strong power and the perfect amount of controllable RPMs.

Rated 5 out of 5 by from Good product at a good price. I have had this Die Grinder for a few months.Only use it occasionally,not every day like some people.It has plenty of power for a small grinder.Seems like quite a bit more than the "cheapie" die grinders that I have used before this.I like the size,and feel of this.A few of the guys that I work with went out,and bought the same one it went over so well.Deffinately recommend this to others.
