I rarely sand anymore, but I have a quick job with 2 and 4 1x4 pine and Id like to give the 32 boards a once-over with my random orbital sander. A few years ago my old Porter-Cable sander gave out, and I replaced it with a Bosch. The P-C had five vent holes, while the Bosch has eight. I have half-used boxes of 5-hole Mirka disks one an assortment with 50, 80, 150, 180, and 220 and the other a box of only 320. These grits have suited my needs well.
Ive been limping along with the 5-hole disks, but I figure that 8 holes would make dust collection more efficient, so Im thinking about leaving the 5-hole disks behind and moving to 8. Ideally, Id like to match the grit collection without needing to buy lots of individual boxes.
I havent bought sanding disks in forever. On first try, Mirka seems hard to buy in an assorted grit hobbyist box. There are a lot of very cheap brands unknown to me floating around Google Im wary of those. Can someone recommend a quality brand with assorted grits and 8 holes? I want to buy once and be happy with the product every (infrequent) time I use it.
