Which grit flap disc would leave the smoothest finish on metal?
When it comes to finishing metal surfaces, flap discs with very fine grits are typically the best choice. Fine grit flap discs will offer the smoothest and most consistent surface finish. Generally, discs with grit between 80-120 will do a good job at finishing, although this can vary depending on the job and the material being worked on.
For tougher materials, a finer grit like 120-150 may be necessary. Generally, the finer the grit, the finer the finish you will achieve. When using a finer grit, it is important to move slowly and steadily over the surface to ensure an even finish.
What is the difference between Type 27 and Type 29 flap discs?
Type 27 and Type 29 flap discs are both abrasive discs used for grinding, finishing, blending and polishing on metal and wood surfaces. The main difference between the two discs is the shape. Type 27 discs typically have a flat, angled surface and are designed for vertical grinding applications.
The airflow that they create gives them a smoother finish than Type 29 discs. Type 29 discs are cone-shaped, allowing them to be used in more aggressive applications since they can reach into recesses and tight spaces.
The shape also helps to create several smaller dust particles that can be vacuumed up easily. Each disc also uses a different grit size, with Type 27 discs typically being 40 grit, 40+ grit, or 60 grit and Type 29 discs typically ranging from 40 grit to 120 grit.
The larger the grit number, the finer the finish generated.
What grit flap disc is for sharpening mower blades?
For sharpening mower blades, a 40-grit flap disc is usually recommended. A flap disc is an abrasive wheel made of overlapping abrasive-coated fabric flaps fastened around a center hub. When the wheel is spun, the flaps spin against the workpiece, allowing it to grind, polish, and deburr.
The 40-grit flap disc is the perfect choice for sharpening mower blades since the relatively lower grit leaves a rougher surface, which is what you want for a mower blade since it helps improve cutting performance.
However, if your mower blades are particularly dull and require a lot of sharpening, you may want to start with a 36-grit flap disc to remove more material quickly. Always remember to make sure the mower blades are properly secured in a vise for safety.
Can you use flap wheel to sand wood?

Before you start sanding, make sure to use a grinding disc to remove any larger pieces of material from the wood surface. Also, it is important to select a flap wheel that is designed for sanding wood.
Once secured to your power tool, pressure must be even, steady and light and you should use the tool over the entire surface. To ensure a smooth finish, you should use multiple grits, starting from a 60-grit and successive finer grits up to and remaining at a 120-grit.
Flap wheels can also be used to remove rust, paint and sealants.
What grit flap disc should I use?
The grit of flap disc you should use for a particular project will depend on the material and the type of work you are doing. Generally speaking, you can use a coarser grit flap disc (40, 60, or 80 grit) for material removal, and a finer grit flap disc (120, 120+, 150, 180, or 220 grit) for finishing.
If you are working on a softer material, like aluminum or paint, you will likely want to start with a lower grit like 40 or 60. If you are working on harder materials, like steel or stainless steel, you may want to start with a higher grit like 120 or 120+ depending on the type of finish you are looking for.
Generally the higher the grit, the finer the finish.
What are flap discs used for on an angle grinder?
Flap discs are designed to be used on an angle grinder and are used to cut, grind, or finish metals and other materials. The discs are made up of overlapping pieces of sandpaper or abrasive-coated material that form a blocked shape.
These discs are rotary-driven and are rotated at a high speed when being used.
Flap discs are most commonly used for polishing, grinding, blending, and finishing applications. When using a flap disc, the overlapping pieces of material form a cushion effect that allows them to be used on surfaces with curves, contours, and angles for a smoother and more even finish.
Flap discs are also used for high-level stock removal, making them ideal for grinding applications. They can be used on stainless steel, iron, non-ferrous metals, composites, and exotic metals.
When selecting a flap disc, there are many factors to consider, such as grit type and size, bond type, abrasive type, and angle of attack. Additionally, the direction of travel and the speed of the blade should also be taken into consideration.
The right disc will ensure the best results for any given job.
Do flap discs expire?
No, flap discs do not have an expiration date as they do not have any ingredients in them that would spoil or expire over time. The abrasive material used to make flap discs is made of hard minerals that are designed to last and resist wear over long periods of time.
As long as your flap discs are stored properly and not exposed to water or extreme temperatures, they should last you for a very long time. It is always a good idea to use the oldest discs that you have stored first, as they may be more brittle over time and thus be less effective.
Can you use an angle grinder flap disc for wood?
No, you cannot use an angle grinder flap disc for wood. Angle grinder flap discs are designed to be used on metal surfaces and can generate excessive heat when used on any other surface. Additionally, flap discs are designed to create a fine finish on metal surfaces, while woodworking projects often require a rougher finish which would not be achieved using an angle grinder flap disc.
