Rust can be a huge nuisance when it forms on tools, cars, or any other metal surface. It’s often difficult to remove and can cause significant damage if not addressed quickly.
There are a few different methods you can use to remove rust, and one of the most popular methods is using a grit flap disc. But what grit flap disc should you use for rust removal?
In this article, we’ll discuss the different types of grit flap discs and their uses, so you can choose the right one for your project.
What are grit flap discs and what do they do?
Grit flap discs are abrasive discs that are designed to remove rust, paint, and other debris from metal surfaces. They are typically made from aluminum oxide or zirconia, and they come in a variety of sizes and grits.
Grit flap discs are attached to a power drill or grinder and they spin at high speeds to remove rust quickly and efficiently. When choosing a grit flap disc for rust removal, it’s important to consider the size of the disc, the type of metal you’re working with, and the severity of the rust.
How to remove rust with a grit flap disc? Step By Step
To remove rust with a grift flap disc follow the steps:
1. Choose the right grit flap disc
The first step is to choose the right grit flap disc for your project. If you’re working with a small area of rust, you can use a lower-grit disc. For larger areas of rust, or tougher rust, you’ll need a higher-grit disc.
2. Attach the disc to your power drill
Once you’ve chosen the right disc, attach it to your power drill or grinder. Make sure that the disc is securely attached before turning on the power tool.
3. Hold the power tool steady
When you turn on the power drill or grinder, hold it steady as you move it across the surface of the metal. Apply gentle pressure as you work to avoid damaging the metal.
4. Move the disc in a circular motion
Move the power tool in a circular motion as you work your way across the surface of the metal. The abrasive action of the disc will remove the rust quickly.
5. Repeat as necessary
If necessary, repeat steps 2-5 until all of the rust is removed from the surface.

Which grit is best for rust removal?
The best grit for removing rust is typically in the range of 36 to 60. The higher the number, the finer the abrasive and the less aggressive it will be on the metal surface.
For most applications, a 40 or 50-grit flap disc will work well. If you’re working with a small area of rust, you can use a lower-grit disc. For larger areas of rust, or tougher rust, you’ll need a higher-grit disc.

What is difference between Type 27 and Type 29 flap discs?
Type 27 flap discs are flat. Type 29 flap discs have a slight angle, allowing for more aggressive grinding. The type of disc you use will depend on the application.
For most applications, a Type 27 disc will work well. If you’re working with a small area of rust, or if you need to remove rust quickly, you can use a Type 29 disc.
What is easiest way to remove rust quickly?
There are a few ways to remove rust quickly, including:
- Using a power drill or grinder with a grit flap disc
- Using a wire brush attachment on a power drill
- Using sandpaper or steel wool by hand
The easiest way to remove rust will depend on the amount of rust and the size of the area you’re working on.
If you have a small area of rust, you can remove it by hand using sandpaper or steel wool. For larger areas of rust, or tougher rust, you’ll need to use a power tool with a grit flap disc or wire brush attachment.
Can I use a grinder to remove rust?
Yes, you can use a grinder to remove rust. The best way to do this is to attach a grit flap disc to the grinder and work slowly and carefully over the rust.
What are sanding flap wheels used for?
Sanding flap wheels are abrasive tools used for finishing metal surfaces. They are mounted on a power tool, such as a grinder, and spun at high speed.
Flap wheels are made of overlapping strips of abrasive material, which wear away at the surface of the workpiece as they spin. This action produces a smooth, even finish.
Flap wheels are used for a variety of applications, including removing rust, preparing metal surfaces for painting, and polishing metals.
Grit flap discs are a popular choice for rust removal because they offer a combination of abrasion and cutting power. They can be used on both ferrous and non-ferrous metals and come in a variety of sizes to fit different applications.
Rust can be a huge headache to remove, but with the right tools and techniques, it can be done. When used correctly, it can quickly remove even the most stubborn rust stains.
Make sure to use caution when using this type of disc, as it can create sparks and fly debris. Be sure to read the manufacturer’s instructions carefully before using one of these discs.
