2. Polishing


When it comes to polishing on a bench grinder, all you have to do is remove one of the grinding wheels and replace it with a polishing wheel. The process is the same as replacing a normal grinding wheel with another normal grinding wheel.

Just make sure you get the right-sized arbor or you will have to make another trip to the store and get the correct one. The polishing wheel works best on lower speed bench presses and gives you more control over what you are doing.

The key is not to let your self be distracted and not to let your eyes wander. Keep your eyes on the wheel and the object you are polishing and keep your concentration on what you are doing.

The polishing attachment is not that elaborate and one tip you may find useful is that you may want to use an extender to help you polish correctly. An extender helps give you more room to maneuver making it easier to bring your object to a beautiful shine.

3. Buffing


When you want to do a little buffing on your metal objects, it is not that hard to do. The key is to get the right wheel to handle all the buffing duties. Like polishing, the buffing wheel is the bench grinder attachment.

Changing the wheel is the same as changing the grinding wheel and as described in the polishing section. When you use the buffing wheel, you do not want to use top speeds. If you have a variable speed bench grinder, then the lower speeds give you the best results.

Also, you will want to remove all the guards and tool rest before you buff. With those items attached, you will not have enough room to do a good job of buffing. It is possible to use a larger sized buffing wheel on a 6 or 8 inch bench grinder. You may need to buy and use an adapter to make it fit right and still give you room to work.

4. Dust Collector


It is possible to get a dist collection system to handle all the fine metal dust you are producing as you grind. Some of these systems are quite large and work with 7 and 10inch bench grinders.

They also can be quite expensive to buy. Plus, you will have to take the time to set it up properly before it makes your bench grinding life easier. Regular 6 and 8-inch bench grinders come with built-in dust ports that allow you to attach dust collection systems.

Dewalt does make a dust controller that has a universal hose fitting. It should work on most bench grinders and help you keep the dust down in your shop. The cost will range depending on the model and style you choose to use.

Knowing what to look for will save you a lot of time and possibly a lot of money. You want to make sure you get the right attachment for the bench grinder you own. Here are some characteristics to look for when searching for the right attachment:

  • Compatibility - not all attachments have a universal fit., You have got to make sure the attachment will fit your bench grinder and work safely.
  • Belt sizes - when using a linisher or sander attachment, check the belt sizes you need. Plus, look at the grit strengths. You want the right belt that will hold up and fit on the attachments.
  • Capability - for example are the dust collectors that are available for bench grinders, can they do the job and do it well? The same goes for all attachments, you do not want an inferior product on your bench grinder as that can lead to many issues later on.
  • Wheels - you want to make sure the polishing and buffering wheels will match up with your bench grinder. They need to match the arbor size plus the speed of the grinder.
  • Extension - will the attachment provide you with the right amount of extra length you need to make sure the other attachments work without interference.
  • Quality of construction - again you do not want an inferior made attachment. This will only cost you more money to replace it when it breaks or does not work properly.
  • Stability - this pertains to bench grinder stands and you need to have a stable stand if you are going to get your work done right.
  • Height - again this applies to the stand, It should be adjustable and have a fair-sized height range. Also, its platform should be large enough to hold your bench grinder with ease.

Some Final Comments

Of course, not all bench grinding attachments will fit your hobby or grinding duties. Just pick up those items that fit in well with what you do in your spare time. The key is to know what you are looking for and how to use it correctly.
