What Grit Flap Disc For Sharpening Mower Blades

There are a few things to consider when purchasing a grit flap disc for sharpening mower blades. The first is the type of material the disc is made from. There are two main types of flap discs: those made from aluminum oxide and those made from zirconium oxide.

Aluminum oxide is the cheaper of the two options and will work well for most people. However, if you are looking for a disc that will last longer and provide a better finish, you may want to consider spending a little extra on a zirconium oxide disc. The second thing to consider is the grit of the disc.

The higher the grit, the finer the abrasive and the smoother the finish. For most people, a 40-grit disc will be sufficient. However, if you are looking for a really smooth finish, you may want to consider a 60- or 80-grit disc.

Finally, you will need to decide what size disc you need. The most common sizes are 4.5 inches and 7 inches. However, you may be able to find discs in other sizes as well.

The size you choose will depend on the size of your mower blades and how much metal you need to remove.

If you’re looking for a grit flap disc to help you sharpen your mower blades, you’ve come to the right place. In this blog post, we’ll go over what grit flap disc is best for sharpening mower blades. We recommend using a 36 grit flap disc for sharpening mower blades.

This grit will give you a nice, even edge on your blades without taking too much material off. If your mower blades are especially dull, you may need to start with a coarser grit flap disc, like 24 grit. But for most blades, 36 grit is a good starting point.

If you’re not sure which grit to use, or if you’re having trouble getting a good edge on your blades, stop by your local hardware store or ask a professional. They can help you choose the right grit flap disc for your needs.
