Summary: Good sandpaper for hardwoods
Comment: I have been using this Mirka sandpaper (grits from 80 to 220)on my Porter Cable sander for about six years. I build fine furniture and find that the Mirka paper holds up well on cherry and walnut. It cuts fast and seems to last a fairly long time (a few hours of sanding time). When it does wear out I typically keep a few sheets around to use as a "finer" grit or to do hand sanding. I have not had any sheets disintegrate. It also holds well to the hook and loop on my P-C.

Summary: Good value for $
Comment: Bought a box of this to go with my PC 343 sander. Don't make the same mistake as I did. The PC 343 is 8 hole. This sandpaper is 5 hole!
But other than my mistake in ordering it, I have used it with the PC343 and it sands and sands and sands! The paper is heavyweight and last a lot longer than what I was using with my C-backed 3M sander. Picks up dust reasonably well considering I am only using approx 2 or 3 out of the 5 holes. Probably the best sand paper I have used in a long time.
Price is alright if you are buying just one box. I have found suppliers selling it for $16 for all grits. If plan on getting several boxes or the higher grits, it is available from other online suppliers for $16 a box (Plus $6 shipping). Just do some surfing, you may get better deals from time to time with store promotions.

Summary: From a Professional that knows the difference!
Comment: I make a quality product and I know that quality abrasives make a big difference. Before I finished using the 1st disc, I KNEW I was using a quality product. Lasts twice as long as others, yielding a superior finish with less fatigue.
This is one of the best discs I have ever used, and the price makes these Mirka discs an outstanding value!

Summary: Don't run out!
Comment: 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.
