5PCS 115mm Vacuum Brazed Ultra-Thin Abrasive Discs - Precision

In this review the 5PCS 115mm vacuum brazed ultra-thin multi-pore flat abrasive discs are assessed for tradespeople and serious DIYers who work with stone and tile. The bottom line: these 5" discs deliver focused, precise material removal on porcelain, glass, ceramic tile, granite and marble, and the main reason to buy is their ultra-thin, vacuum brazed construction that balances cutting efficiency with a smooth finish. The set of five gives enough quantity for multiple small jobs or progressive grit work, and this review highlights real-world performance and limits.

Key Features

• Versatile Grinding Disc: The set is suited for a wide range of hard surfaces, allowing the same disc type to be used across porcelain, glass, ceramic tiles, granite and marble.
• Ultra-Thin Design: At just 0.05 in thick, the discs provide controlled, precise grinding that helps avoid excessive material removal on delicate edges.
• Multi-Pore Surface: The patterned multi-pore face helps with efficient material removal while promoting a smoother finished surface compared with a coarse single-pore disc.
• Vacuum Brazed Bond: The brazed diamond layer adheres securely to the backing for durability under sustained grinding tasks.
• Five-Pack Convenience: Receiving five identical discs allows for rotation between tasks or replacement when one disc wears, which is useful on longer jobs.

Who It's For

These discs are best for contractors, tile setters and advanced DIYers who need a thin, precise abrasive for shaping and smoothing hard surfaces like porcelain, ceramic tile and natural stone. The set is practical for jobs where control and a fine finish are more important than aggressive bulk removal.

Those who should look elsewhere include users seeking very aggressive stock removal for heavy demolition or grinders that require thicker support for extreme lateral stresses; this ultra-thin format favors precision over brute force.

Pros & Cons

Pros

• Thin profile gives excellent control for edge work and finishing on tile and stone.
• Multi-pore face balances material removal and surface finish for cleaner results on glass and porcelain.
• Vacuum brazed construction improves durability compared with simple bonded abrasives.

Cons

• Ultra-thin discs are not ideal for aggressive, high-volume stock removal or heavy structural grinding.

Our Verdict

The 5PCS 115mm vacuum brazed ultra-thin multi-pore discs are a strong choice when precision and finish matter across tile and stone work; they offer practical value in a five-pack and the vacuum brazed build improves longevity. Buy this set if you need controlled grinding and polishing on hard surfaces, but consider thicker or more aggressive discs if heavy stock removal is the primary goal.
