" 9孔（8外孔+中心孔）H&L INDASA 紅色樹脂砂碟

The eight outer holes plus center hole really do keep the dust down—my workbench stays much cleaner than with my old solid discs. They cut smoothly and the hook-and-loop backing grips tight without slipping during use.

I picked up a pack of the 6-inch size and the 9-hole dust extraction really keeps my work area much cleaner than standard discs. The red resin bonding seems to hold up well through several uses without the grit wearing off too fast.

These red resin discs cut through the material much cleaner than the old ones I was using, and the 9-hole pattern really does keep the dust down. The hook-and-loop backing holds tight even under heavy pressure, so I've been getting consistent results with my 5-inch sander.
