SOURCE: Black & Decker 4 1/2 grinder gets very hot

You will see vents near the head of the grinder. Make sure your hands are not blocking when in use. Also another thing I like to do with my grinders is removed the head cover (gear box) and replace the lube with a good grade of grease. I suspect if you open yours it will look like an orange wax substance. Clean and re-lube. They do run on the warm side.

SOURCE: I have a DW402 4.5'' angle grinder and do not know how to remove the blade to install a new one. Could someone help please?

On top of the head there is a button to press to lock the blade arbor. Press it down and turn the blade by hand until it locks in place. Then you need either a spanner wrench or nut wrench depending on which arbor nut you have. Grinders usually come with whichever wrench they need. Most grinders have an arbor nut with two or four holes and require a spanner wrench with two studs that fit into two of the holes to remove the arbor nut. Some have an arbor nut with a hex fitting, like a regular nut & bot setup, that the arbor wrench fits on. If you don't have the proper wrench sometimes you can get the arbor nut off with a pair of vice grips or pliers. You will want to turn the nut in the same direction as the blade spins when the grinder is on to remove it. When you put the new blade on, get the arbor nut hand tight, it is self tightening and will get tighter as you use the grinder.

The button on the top of the gearcase is used to lock the shaft only when you are tightening the nut. It is of no use when removing the nut. The DW402 was an early model and made no provision for removing the nut.

Hi...I have a Black and Decker 4247 angle grinder that I haven't changed the disc on in YEARS...I can't remember if the clamp nut is right hand threaded or left...please help! Thanks lots!


Which ever way your grinder spins when turned on is the same direction the lock nut has to be turned to remove it. This makes sure it's self tightening when in use. More often than not they're right-tight, left-loose.

I was given an old grinder a while back (and not told it needed a handle, but luckily found one), but don't know how to get the wheel/blade off to put on another. There is a "key" with it,...


there is usually a spindle lock on the gearcase somewhere that you need to depress while turning the spanner wrench. If this fails what I have done to remove a "stubborn" wheel is use a punch UNPLUG TOOL FIRST and hit against one of the holes counterclockwise to loosen the nut.

How do I remove the cover of the black and decker angle grinder.It stopped working,I think a wire is loose inside,but i cannot get it open to see if I am right. Can anyone help? Thanks. Gerry


Hi Gerry,
The body of the grinder should be in two halves. Normally there are two or more screws holding the plastic parts together but these may be hidden behind plastic stoppers. See diagram:

http://servicenet.blackanddecker.com/Products/DetailDiagram?isId=true&productNumber=11651&selectedType=16337#

Remove the screws and it should be possible to split the case.

Hope this helps!

I have a 7" angle


There are 3 versions of the 7" grinder model 4074. Sears Parts Direct has the manual for sale http://www.searspartsdirect.com/partsdirect/part-number/BLACK-DECKER-Parts/Grinder-Parts/741333-00/0009/900/Model-4074/1228/0721050?keySuffixId=NA&productTypeId=x&searchModelNumber=4074&subCompDesc=Unit%20parts&brandDesc=BLACK&DECKER&modelDesc=7 .

Black and Decker has pdf versions of the manuals for many of their products are here: http://www.blackanddecker.com/manuals.aspx . However, check the model number on the grinder. 4074 doesn't come up as a valid model. The usual model numbers start with alphabetic characters to indicate the type of tool. The site lists where to look for model numbers.

I hope this helps.

I need a clamp nut for a B&D angle grinder model #6247. Where can I purchase one??


The clamp nut for angle grinders have a standard thread.
It should be possible to get one at a large tool store. You may have to buy a new wrench for tightening the nut though.

You don't. It's a double insulated tool.
