砂輪，氧化鋁（旋轉工具用），10 件 CLEARANCE

These grind through rust and hardened steel like nothing else I've tried, and they fit my Dremel perfectly. For a clearance price, getting ten wheels that hold up this well feels like a steal.

The aluminum oxide grit bites into cast iron and welded joints without loading up, which is exactly what I needed for cleaning up some rivets on a gate. At this clearance price, I grabbed two packs just to have them on hand.

Swapped out a rusty old bolt on my truck's frame, and these wheels cut through the rust and hardened steel like butter. The aluminum oxide grit held up better than the generic ones I've used before for that job.
