320 粒度 研磨套，3 入

These sleeves fit the drum sander perfectly and the 320 grit leaves a noticeably smoother finish than the lower grits I'd been using. I'm glad the pack comes with three, since I tend to wear them out fairly quickly on hardwoods.

Slapped a set of these on my drum sander and the 320 grit is perfect for final passes without tearing up the wood. Each sleeve held up through a full project without shredding.

Finally getting that silky smooth finish I was after on my last project — these sleeves hold up way better than the cheapies I've been using. The 2-inch diameter fits my drum sander perfectly, and three in a pack means I won't run out mid-sanding.
