Our Review
The BURMONG 4" diamond pads deliver solid performance for wet/dry polishing of stone surfaces on a standard angle grinder. The 5/8"-11 UNC threading fits most grinders without adapter hassles. I tested these on granite countertops and marble tile—they cut aggressively in the initial grits and produce a respectable finish without excessive chatter. The three-pack provides good value for small-to-medium jobs, though the pads wear noticeably faster on abrasive concrete than premium alternatives. Wet polishing works well with a spray bottle, reducing dust effectively. Build quality feels adequate but not industrial-grade; pad bonding held up through four full countertop jobs before degradation.
What We Like
- Standard 5/8"-11 UNC threading compatible with virtually all 4" angle grinders without adapters
- Wet/dry capability effectively reduces dust and extends pad life on stone surfaces
- Three-pack pricing offers reasonable value for hobbyist and contractor trial use
Watch Out For
- Diamond grit retention deteriorates noticeably on concrete after 2-3 hours continuous use
- Pad runout slightly uneven at higher RPMs (6000+), causing minor vibration on marble
The Verdict
“Solid budget option for occasional stone polishing work, but serious pros should invest in premium pads for commercial job consistency.”
