7 × 7/8 بوصة قرص رفرف نوع 27 (مسطح) REG ZIRC الولايات المتحدة (سايكلون بواسطة أندرسون) 8600 دورة في الدقيقة 40 حبيبة

That 40-grit bite is no joke — it chewed through rust and mill scale on my steel table in minutes without loading up. The 7/8 arbor fit my grinder like a glove; no adapter needed. For the price, this flat disc is a workhorse for aggressive stripping jobs.

Took off a solid 1/8 inch of weld bead in a single pass with this 40-grit disc, and it still had plenty of life left for the next joint. The flat Type 27 shape lets me get right into tight corners without burning up the backing.

The 40 grit on this 7-inch disc chews through welds fast, and the Type 27 flat profile lets me get a smooth finish without digging in. It held up for a full afternoon of heavy grinding on steel, which is more than I can say for cheaper options I've tried. Worth the money for the runtime alone.
