Mirka 23-615-AP

Sanding discs are made differently and are available in different sizes and grits.

I have chosen the one made of aluminum oxide grain for you.

The Mirka’s assortment of sanding discs can fit in a wide range of sanding tools such as the DeWalt DW421, Bosch 3107, 3725, and the Makita BO5010.

Aluminum oxide has proved to be not only the most effective but also durable grain that has gained trust of many professionals in woodworking.

With this Mirka kit, you get 50 sanding discs per box, whereby each grit has 10 pieces.

The grit included is 80, 100, 120, 150 and 220.

The size of these discs is 5-inch and each has 8 holes.

That being said, the discs can fit in any sanding tool regardless of the brand, as long as it accommodates 5-inch sanding discs with 8 holes.

That’s the advantage of having this Mirka kit for all your woodworking projects.

The discs’ longevity is enhanced by the anti-load stearate and by the high-strength resin bond system.

For anyone enthusiastic about woodwork projects from coarse applications to a smooth finish, Mirka’s assortment of sanding discs is the best choice.

There are sufficient discs for each grit to complete larger projects.

Word of advice: when sanding rougher surfaces, start with the lowest grit and then advance per grit.

You can jump one to the other, but not recommended to jump from, say, 80 to 220 grit.

The finish might not be as smooth as desired.

There’s no specific time.

However, since an assortment is provided, I recommend using each level of grit until the finer grit.
