When you take a look at all of the different options for buffing and polishing products, it’s easy to get a little lost in what is the best tool for what you need at a given time. Each of these tools has different uses and benefits that you should consider before tackling your buffing job. We’d like to help clear things up by comparing the different types buffing and polishing attachments for various power tools you might come across.
Airway Buffing Wheels
At EmpireAbrasives.com, we sell 3 styles of 8” Airway buffing wheels. They are all made with a 3” center plate and a ⅝” arbor hole. They have been designed to be used on an angle grinder, bench top lathe, polisher/sanding machine, variable speed polisher, and more.
Each of these buffing wheels are 16-ply, meaning 16 cotton layers are attached to the center plate. They are attached in a special way that creates pleats throughout the entire wheel. These pleats allow for extra airflow during buffing and allows the buffing wheel to run at cooler temperatures protecting the airway buffs from overheating, which can extend the product's life as well as the workpiece.
The main difference you’ll see between each airway buff is the color treatments. Each color signifies a different level of hardness for each wheel. The hardness/stiffness of the airway buffs should be considered for which step of the buffing and polishing process you’re on, as well as what metal you are working with.
Orange Mill Treated - These are the firmest airway buffs. The stiffness of the orange airway buffing wheels allows them to both cut and color aggressively. These generally work best for the beginning stages of buffing, often using black magic or brown tripoli buffing compound.
Yellow Mill Treated - Yellow treated wheels are 15% less stiff than the orange mill treated. While you can use the yellow mill treated airway buff for both color and cutting, it is ideally suited for color with light cutting. You will likely get the best results from this colored airway buff when using green rouge buffing compound.
Untreated White Domet Flannel - White airway buffs are the softest and most delicate of our three airway buffs. The white flannel is an ultra plush option for getting an ultra high luster and perfect mirror finish. Unlike the treated counterparts, there is no noticeable stiffness.
The airway buffs are designed for you to use the edge of the buffing wheel for the actual polishing, while evenly applying buffing compound bars as the cutting agent. This method is called edge buffing and is commonly used when polishing metal with a buffing wheel or an angle grinder.
This buffing wheel must be used with a specific ventilated flange as to prevent delamination from the steel center. We also recommend always raking your buffing wheels between uses. This will help to prevent compound build up and remove any hardened and burned-on compound from the edges of your wheel. This will help extend the life of your airway buff and help you get more consistent results.
Sisal Buffing Wheels
At EmpireAbrasives.com, we also carry sisal buffing wheels, another buffing and polishing wheel known for their aggressive cutting capabilities. Sisal buffing wheels are made from cellular fibers formed into a thin cord that the buffing wheel is constructed from. These fibers are known for their high strength foundation in creating binders’ twine, cords, ropes, etc. They are naturally abrasive, and the cellular fibers are also grease absorbing.
Our sisal buffing wheels are all closely stitched with a ¼” stitch spacing and spiral sewn. The hardness of the buff is within the spacing of the stitching. The ¼” stitching is the most popular especially when you want a hard buff.
These buffing wheels will provide both polishing and cutting action. Sisal buffs are often the first buffing wheel used for cutting processes, especially for harder metals like stainless steel or iron. They will also remove things such as: stretcher stains, polishing wheel grit lines, light die marks, orange peel, etc. They are most commonly used for finishing roll formed, drawn, and stamped metals. When combined with cloth, they can cut and finish stampings in a single operation prior to preplating.
It also runs cooler due to the airflow from the center of the buff. Sisal buffing wheels have been designed to be used with a bench grinder, bench polisher, bench top lathe, or buffing machine.
When using a sisal wheel it is common to have to add more buffing compound in short intervals such as every 30 to 60 seconds. If using the sisal wheel in combination with the black compound does not take out your scratches then you will need to do further sanding on your workpiece.
In order to extend the life of the wheels and avoid accumulating hardening compounds, it is recommended that you rake your sisal buffing wheels.
Conventional Buffing Wheels
Muslin cotton style buffing wheels are made of high quality, soft muslin cotton. They can come in sewn 20-ply and a loose 60-ply. Muslin cotton is very similar to cotton flannel buffing wheels. The higher the ply count is then the thicker the buffing wheel will be. You can get these buffing wheels as small as 4” and as large as 10” from EmpireAbrasives.com
Spiral Sewn Muslin Buffing Wheels
These are typically one of the most popular wheels chosen for buffing and polishing work. The plies of the cotton muslin cloth are sewn together spirally with ¼” spacing. The tighter spiral sewing allows the wheel to become harder/denser and thus more pressure can be applied to it.
This is commonly used for cutting metal as the spiral sewn muslin buffing wheels excel at both cutting and coarse buffing. They also excel at cutting down more fragile workpiece materials. Each spiral stitched buff is crafted from premium muslin woven cotton cloth that contains between 64-68 threads per inch! The cloth layers are then stitched together from the center and sewn in a circular spiral pattern up to the outer edge of the buff. These have been designed to be used with a bench grinder, bench polisher, lathe, or a drill with a proper mandrel.
Pro Tip - As you use a spiral sewn muslin buff, the edges will wear away, getting closer to the stitching. You can cut away and remove the outermost stitching to use the wheel longer. Removing the stitching also makes the wheel less dense and can be taken out if you need a softer buffing surface. Simply cut the string and pull out the threading.
Loose Cotton Muslin Buffing Wheels
Loose cotton buffs are used with polishing compounds and are perfect for the final finishing work. These buffing wheels come in 60-ply and are unstitched like the spiral-sewn alternative, but are sewn once around the arbor hole. The edge of these buffs are soft and feel almost felt-like.
Because of the softness of these wheels, they conform to the workpiece you are polishing as you apply pressure. This makes them the perfect solution for curves, contouring, and any other awkward angles/crevices much more easily than their sewn counter parts. They also naturally generate less heat than their stitched counterpart.
The loose cotton muslin buffing wheels are also excellent for light cutting and coloring on nearly all metals and plastics.
Like the spiral sewn, they are designed to be used with a bench grinder, bench polisher, lathe, or a drill with a proper mandrel.
Felt Polishing Discs
Felt polishing discs and wheels are crafted from tightly compressed, high-quality Australian wool. The felt polishing discs are medium hardness and are used for all-purpose buffing and polishing with various polishing pastes or buffing compounds. They are versatile and can be used with any compound for both polishing and cutting. They retain their edge, and are excellent for angles and corners.
Black Hawk Abrasives Polish Plus felt discs have been specially designed to offer flexibility to polish on contoured surfaces while providing a cooler working action to prevent burning on the workpiece of discoloration. They are available in the 4.5” x ⅞” Flap Disc, 4.5” x ⅞” Flat Disc, 2” Quick Change, and the 3” Quick Change.
The polishing flap discs work great with angle grinders. Whereas the quick change polishing discs are versatile and with the backing pad can be used in die grinders, drills, and air grinders.
Buffing Drums
Buffing drums are specially made for the final stages of both buffing and polishing on different metals and some wood surfaces. The drums have a much larger surface area than other polishing tools with a wide 4” wide working surface. That allows the operator to cover a lot of surface space and cut down on the time spent buffing and polishing for large projects such as: RV’s and airstreams, full vehicles, and large metal fabrication prep work. EmpireAbrasives.com’s selection of buffing drums have a hub that fits a ¾” keyed shaft and were created to be used on surface finishing machines and linear grinding machines such as: burnishers, burnishing machines, contouring grinders, and surface conditioning tools.
Spiral Sewn Buffing Drum
Black Hawk Abrasives’ spiral sewn polishing drums are made of soft premium muslin cotton sheets that have been stitched together in a spiral pattern that starts from the center of the drum and sewn circularly to the outer edge of the buffing drum.
These drums are to be used with a buffing compound and are specially designed for the first step in cutting, coloring, and polishing surfaces. Due to the size and design they are able to cover larger areas much more quickly than a standard polishing disc. They are a favorite buffing tool among many auto body workers and metal fabricators since they can help polish large jobs in less time than standard buffing wheels.
Flap Buffing Drum
Black Hawk Abrasives’ flap buffing drum is a great last step for polishing and buffing larger workpieces. They have been designed to work well on both flat and curved surfaces. This gives the operator the ability to create a perfect mirror finish on various different materials. The continuous rotation of the drums combined with the one-way pulling motion allows the operator to avoid buffing swirls when using the flap buffing drum unlike when using polishing wheels that spin and often create these swirl patterns.
The premium felt wool flaps have been positioned radially and fan out from the drums center. This design will allow air flow through the flaps and reduce heat on both the drum and the workpiece. Like all polishing wheels, each drum should be dedicated to one polishing compound and be reused with that compound only. A buff rake to get the hardened pieces off.
