4 1/2" X 7/8" 研磨片 TYPE 29 (斜角) - ZIRC 進口 HD (雙層厚度) MACRODISC.

The double thickness on these flaps really holds up under heavy pressure, and they cut through rust and welds faster than standard discs I've used.

I've been using this on my angle grinder for heavy weld removal and it holds up way better than the cheaper discs I tried before. The angled Type 29 shape really helps with getting into tight spots without burning through too fast.

The double thickness really makes a difference—this disc lasted through a full day of grinding down welds and still has plenty of life left. The Type 29 angle let me get into tighter spots without flipping the tool around constantly.
