3 in Copper Diamond Polishing Pucks 100# - Long Life Pads

In this review the ComeFloor 3 in copper diamond polishing pucks 100# are examined for tradespeople who need a transitional grinding tool on concrete floors. The bottom line: these hook and loop backed pucks are designed to remove scratches left by metal bond grinding discs and leave a consistent scratch pattern, making them a practical choice for contractors preparing slabs for resin polishing. The reviewer found the aggressive copper and diamond mix durable and well suited to follow metal bond stages before moving to finer polishing tools.

Key Features

• Copper and diamond bond: The blend of professional-grade diamond powder and copper powder creates aggressive segments that remove metal bond scratches effectively.
• Transitional stage use: Designed to be used after metal bond grinding discs and before resin polishing tools to provide a consistent scratch pattern for densifying.
• Hook and loop backing: The 3 in diameter discs are easy to attach and remove from universal ride-on and walk-behind grinders, saving time on the job.
• Durability: The copper bond and diamond mix provides long using life compared with soft polishing pads when tackling coarse scratch removal.
• Universal match: Compatible with common floor grinders such as Sase, Diamatic, Lavina, Husqvarna, WolfPack and Edco, making them versatile for rental fleet or contractor kits.

Who It's For

The ComeFloor 3 in 100# copper pucks suit concrete contractors, flooring specialists, and rental operators who need a robust transitional tool to bridge metal bond grinding and resin polishing. They work well on job sites where consistent scratch uniformity is required before densifying and subsequent polishing stages.

These pucks are not aimed at homeowners doing light cosmetic polishing or anyone needing final resin polish pads; users who want a fine finish in a single step should look to resin polishing tools instead. Also, if you require a range of grit progression in one product, this single-grit set will not replace a full polishing sequence.

Pros & Cons

Pros

• Aggressive copper-diamond segments remove metal bond scratches efficiently.
• Hook and loop backing makes quick pad changes on ride-on and walk-behind grinders.
• Durable construction gives a longer working life than many soft polishing pads in transitional stages.

Cons

• Single grit 100# means you still need additional resin polishing pads for a finished shine.
• May be more aggressive than required for delicate restoration tasks.
