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

Thank you for your recent inquiry with The Home Depot. I believe it would be best to reach out to the manufacturer for assistance. The manufacturer is Dewalt and their customer service department can be reached at 1-800-4-DEWALT.

Customer Reviews

Rated 4.4 out of 5 by 37 reviewers.
Rated 5.0 out of 5.0 by Great Product Used to strip old paint off a 14' flatbed trailer. Paint was 40 years old. With a wire wheel the paint came off well. Grinder ran with no problems. Removing the side handle to get into tight places was easy. Good buy. September 27, 2015
Rated 3.0 out of 5.0 by Switch failed Switch failed at approximately 100 hours of use. Brushes are still in good order and everything else appears fine. $12 for replacement switch but i wouldn't expect a failure like this. I have a Ryobi from years ago and it is still working, probably only paid $20 for it. I was weighing the option to just buy another Ryobi for the same price of the switch and shipping for the Dewalt. August 16, 2015
Rated 5.0 out of 5.0 by Really solid unit I borrowed one of these from a friend to cut ~200 cinderblocks to build a wall. After my wall, I kept it for a while and used it for countless other cutting jobs including rebar, frozen bolts on my truck, steel brackets. When he asked for it back, I had to go buy one for myself. I think 10-Amp is really about the lowest you'd want because as the blade dulls, even 10A is only just enough to do the job. The handle can be moved to right or left side, which is great depending on the job. This tool is really great. April 28, 2015
Rated 4.0 out of 5.0 by Good purchase The angle grinder helped us cut a bearing race off a AHU shaft .this product helped with the final outcome getting the AHU up and running quickly. May 12, 2015
Rated 5.0 out of 5.0 by 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. July 27, 2013
Rated 5.0 out of 5.0 by solid well built and powerful It's an angle grinder. It does what it is supposed to do and does it well. I found it to be more powerful than I expected for a small grinder. Changing disks is easy. April 25, 2015
Rated 4.0 out of 5.0 by Great grinder Good value for the money. We abuse these cutting out mortar. The dust and sand eventually win the fight by getting into brushes and ruining the inside parts. Without the dust they perform great. March 27, 2015
Rated 4.0 out of 5.0 by Nice Grinder but take note! You have to buy the flanged bushing separately! Doesnt come with one as the description alludes to. Make sure you buy one before you get it home and realize it doesnt accept flat discs without it. February 6, 2015
