P1 EXV™ Single Row Cup Wheel EXV04CH

Pearl P1 EXV™ Single Row Cup Wheel — Aggressive Grinding & Coating Removal on Concrete and Masonry

The Pearl P1 EXV™ Single Row Cup Wheel (EXV04CH) is a 4" sintered diamond cup wheel engineered for professional-grade grinding and coatings removal on concrete, block, stone, and other masonry materials. Designed for contractors and trades professionals who demand fast stock removal, the single row segmented configuration delivers a more aggressive grinding action compared to double row alternatives. Compatible with both wet and dry operation, this cup wheel mounts via a standard 5/8"-11 arbor and is built using Pearl's DST (Direct Sintering Technology) for consistent segment performance throughout the wheel's life.

Technical Specifications

Product Attributes

The P1 EXV™ line is available in both single row and double row configurations, as well as 4" and 7" diameters, giving contractors the flexibility to match the wheel to the job. The single row design prioritizes aggressive stock and coating removal over the smoother finish profile of the double row variant, making it the right choice when speed of material removal is the priority.

Key Features & Benefits

Single Row Segmented Design for Aggressive Removal

The single row configuration provides faster stock removal and a more aggressive grinding action than double row cup wheels. This makes it the preferred choice when contractors need to strip coatings or grind down high spots quickly without sacrificing control.

DST – Direct Sintering Technology

Pearl's Direct Sintering Technology bonds the diamond segments directly, producing consistent cutting performance from the first pass to the last. This manufacturing process contributes to the wheel's durability and reliable segment integrity under demanding job site conditions.

Wet or Dry Operation

The EXV04CH is rated for both wet and dry use, giving contractors the flexibility to adapt to job site requirements. Wet grinding helps control dust and extend wheel life, while dry operation allows for use where water is impractical.

Standard 5/8"-11 Arbor Compatibility

The 5/8"-11 threaded arbor is the industry-standard mount for angle grinders, ensuring broad tool compatibility without the need for adapters. This allows for fast wheel changes and straightforward integration into existing tool inventories.

Professional Grade Performance at Competitive Value

The P1 EXV™ series is positioned to deliver professional-grade results at an excellent price point, making it one of the best values in the diamond cup wheel category according to Pearl. Contractors can maintain productivity without overspending on consumables.
