Customer Questions & Answers

Was is the part number for a Type 1 Closed Guard for D28402W Grinder, and where can I find one?

The manual says I need one for cutting metal, but the manual does not give a part number for the Type 1 Closed Guard for DeWalt Grinder 4.5 inch Model D28402W. Thanks, Freddy
Asked by: Freddy
White Cap or HD Supply has one, but I think they are moving toward the newer version of this model. Good Luck

Customer Reviews

10-amp 4-1/2 in. Small Angle Grinder is rated 4.4 out of 5 by 38.
Rated 5 out of 5 by from Great small grinder I bought this grinder in 2010 after a much cheaper brand melted on me and caught fire. I could not be happier. I've beat this grinder for hours and days at a time and it takes everything I throw at it, from cutting steel and cast iron, to grinding metal, to cutting brick and block and concrete, to wire wheeling rust scale... All the while being run for hours straight in the sun, choked with brick and mortar dust, and dragged through the dirt. Even when I push hard it barely slows down, and has never given me a single problem. I wish it had come with a case but that's a minor detail, Whether you are an amateur or a pro, this little grinder will not disappoint.

Rated 5 out of 5 by from Best Grinder Overall This is one of the most used of all my power tools. Its portability is outstanding for getting into cramped spaces. It has the power of a larger grinder for cutting, brushing and if I really need to say....grinding. I am impressed!!!! Its the handiest tool I have. My friends always want to borrow it...I have recommended it to countless workers on jobsites. It is by far, the best grinder I have ever owned.

Rated 3 out of 5 by from Great for home use only! Runs good. But, over heats when used for more then 20 minutes. Brushes need replacing, often. Great for home projects. But, not for industrial use.

Rated 5 out of 5 by from A must have tool! I bought this grinder as a main tool for the rust repair/ restoration of my 77 GMC step side. It does everything I bought it for and I keep finding new uses for it. I plan to buy another just to speed up the process, so I am not switching ends so often.

Rated 5 out of 5 by from Buying a second one Love this grinder. Bought one for the shop at work and it gets beat up and has never had a problem in over 2 years. Am buying another one tomorrow for home. Only thing I would like is a sturdy box to lug it around in.

Rated 5 out of 5 by from qualit product At first I purchased a cheaper brand of angle grinder. I didnt even get what I paid for. It was worth buying a quality brand. Its works well and has lasted for a few months with no issue and extreme use.
