Question: Will these fit a Ryobi OSS450 oscillating sander?
Document: I've got the Porter Cable handheld spindle sander that I occasionally attach to a bench like a traditional model but wasn't able to find the full range of drums through the manufacturer. These fit perfect and allow for a lot more flexibility in my work.
I have three sets of these sander drums. One came with my sander and I bought 2 additional sets. If you use a spindle sander frequently you will find that changing from one sanding sleeve grit to another is a major pain. I keep 100 grit on one set, 150 on the second, and 240 on the third.My spindle sander is not a POWERTEC sander, but these drums are exactly the same diameter and length as those that came with my sander.
works OK
The new drums are too tight in my sanding sleeves. It is a tuff job to get the sleeve off when I want to change the sleeve to another grit.
I wonder why  you get 6  sanding sleeves and only 5 tubes to put them on. You are short the small one.
Answer: yes
