3 吋 R 型 表面調理 快速更換碟 25 包

The hook-and-loop backing on these Type R discs grabs the mandrel firmly—no slipping at all during use. I was able to strip rust off an old metal bracket in under a minute with consistent results. For a 25-pack at this price, they’re a solid value for light blending work.

These discs take rust off metal parts surprisingly fast without digging into the base metal. The 25-pack should last me a while since each one holds up well under moderate pressure.

The Type R mandrel holds these discs firmly on my grinder, which is a nice change from pads that wobble. They did a decent job cleaning rust off a metal bracket, though I found them wearing down a bit faster than I expected for light blending work.
