Mirka 23-615-320 5" Bulldog Gold 8-Hole 320 Grit Grip (Hook and Loop) Sanding Discs - Gold is designed for finishing and heavy stock removal. The durable aluminum oxide grain delivers a fast, exceptionally long lasting cut. Proprietary backing is stronger than other competitive brands using traditional backing. High strength resin bonding for superior grain support. A special stearate coating is used to maximize resistance to clogging and loading. A uniform, semi open coat design produces an even, consistent scratch pattern.

With the 320-grit, you get an amazing, silky finish on your wood surfaces. You can stop sanding at 220-grit, but if you take another step to 320, the wood really is beautiful to the touch! I use these discs all the time on cutting boards and table tops.

I used these disks on my Bosch random-orbit sander. The hook-and-loop backing is strong and holds on through rough sanding. The aluminum oxide sanding material lasts for a good amount of time. I have bought other brands of sanding discs that do last longer, but the Mirka discs definitely hold up well.

The discs are packaged in a sturdy box with a cover, which makes it easy to dispense them as needed. Also, having them stored in a box keeps them clean, which helps the hook-and-loop function. This actually helps out a lot in the shop. Other brands come wrapped in plastic, and you have to find a container for them, or let them sit on a shelf and get full of sawdust. I appreciate this extra touch.

The paper stock is somewhat thin, but this does not really affect their use. Since they are stored in a box, they stay flat. Other brands, which are stored in bags, get curled up on the edges.

Bottom line: these are good quality sanding discs that last for a good amount of time, are a good value for the money, and are packaged in a convenient way.

Don't run out!  Jun 22, 2000 By Wayne Cease
I like to get the boxes of sand paper so I don't run out. These match my Dewalt DW421 just like they are suppose to.

They line up easily and are easy to attach and detach later. But they stay put while in use.

It is much easier to get a smooth finish if you step your way up through the grits. Get them all and work your way up and you will get a nice smooth finish.

I don't always go to 320 grit, but many of my projects have a more natural finish (oil, shellac and wax) so those really nice the 320 grit for a super smooth finish.

Best Sandpaper for the Money  Apr 08, 2007 By T. Malyszko
I've been using Norton Brand for years just because it is readily available locally. When it came time to stock up, Mirka was recommended, so I decided to give it a try, especially since a 50-pack costs $17, vs. $9 on a 10-pack of equivalent Norton Sandpaper.

After using the Mirka for a few weeks, there is no comparison. The Mirka last longer and the 320 grit leaves a smoother finish than any other 320 grit paper I've used. As I use up my Norton paper, I will be replacing it exclusively with Mirka H&L disks.

Great value  Nov 29, 2010 By Bobby Orr "scasmflop"
These sanding discs work great and have a better life than the home-improvement chain alternatives. Being a fraction of the price makes them a very good value. If you are purchasing for the first time, make sure to figure out whether your sander takes 5-hole or 8-hole sanding discs.
