Is it possible that you have misplaced the inner clamp washer? I looked at a print on this tool and that is the only thing that I can see unless it has major bearing problems. Did this just start after a wheel change and what is the possibility that the wheels are too big and hitting the housing or there is a build up of grinding dust in the bell where the wheel turns. Most of the parts for this tool are probably discontinued. You can go to Dewaltservicenet.com and under manuals type in your model number for a copy of the breakdown that I looked at.

On/Off switch is hard to push


It's probably best to disassemble it and clean it up inside, especially if it's never been cleaned inside before.

Turns slow


Lubricate the bearings. The lube has probably hardened. The shaft should turn freely. You can clean the bearings using CRC226 available at Home Depot elec dept.

If the unit has ball bearings they may need to be replaced.

Black & Decker 4 1/2 grinder gets very hot when in use


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.

Need an on/off switch for a buffalo bench grinder model B-6CB 1/2 hp. 41/2 amp. serial #775713


I had the same problem with a Northern Tools bench grinder. These are made in China and parts are hard to come by. I had enough room after removing the old broken on/off switch to install a single pole 15 amp light switch like you use in your home. I simply installed it horizontally and then put the switch cover on. It works perfectly. If you do not have enough room then look for any 15 amp or larger switch that will fit in the housing. Any on/off switch will work. You could even mount the switch on the bench in a switch housing and run the wires from the grinder to the switch and back if need be. Just be safe and make sure there are no exposed wires. As a last resort you could remove the switch connect the wires, eliminating the switch and use a plug in wall switch such as this. 4147a14.png

Older black & decker bench grinder


Usually a new wire wheel comes with different size bushing just for the problem you are describing. Either that or take it back and get one specifically for your tool.

Bench Grinders Usage


Grinding is the fastest way to deburr a sharp corner or dress the end of threaded rod or bar stock that's been cut to length. Fit a grinder with a wire wheel, and you have a handy tool for removing rust. Then switch to a buffing wheel and you're ready to polish metal to a mirrorlike sheen. But for most of us, grinders are essential for shaping and sharpening hardened tool steel and high-speed steel.

Precision work question


Bench grinders aren't designed for precision work. In fact, they're really freehand tools that rely on a good eye and careful touch. And while you can take some tools, like drill bits or turning tools, right from the grinding wheel to the work, it's common for grinding to be a relatively coarse, preliminary shaping procedure, followed by careful honing on a whetstone.
