Bihui 4.5" (115mm) Diamond Polishing and Grinding Flap Wheel

The Bihui 4.5" (115mm) Diamond Polishing and Grinding Flap Wheel (DPM Series) is a professional-grade, multi-action surface dressing attachment engineered for shaping, beveling, and smoothing dense architectural materials. Combining the aggressive material removal of a diamond cup wheel with the fine control of a polishing pad, this heavy-duty wheel is highly recommended for tilers, stone masons, and countertop fabricators. Built with a combination of industrial diamond and silicon carbide flaps arranged in a high-efficiency spiral layout, it allows operators to clean up rough cut edges and fabricate factory-smooth finishes on porcelain and natural stone using a standard angle grinder.

Why Choose the Bihui 4.5" Diamond Flap Wheel?

• Aggressive Spiral Turbo Design: The overlapping flaps are configured in a specialized spiral turbo layout. This geometric arrangement optimizes airflow to keep the workpiece cool while delivering an exceptionally fast, smooth, and vibration-free grinding action that minimizes operator fatigue.

• Upgraded Metal Backing Plates: Unlike standard economy flap discs that utilize flimsy fiberglass or plastic backings, these premium wheels feature a reinforced, heavy-duty metal backing plate. This structural upgrade drastically increases the working lifespan of the disc, ensures perfect balance, and prevents flexing under heavy lateral pressure.

• Hybrid Diamond & Silicon Carbide Flaps: Constructed with a high-performance blend of industrial diamond grit and durable silicon carbide. This advanced material composition provides the extreme hardness needed to slice through dense vitrified glazes, while maintaining the flexibility required to contour smoothly without gouging the stone face.

• Available in Three Professional Grit Levels: To guide an edge seamlessly from initial heavy stock removal down to a refined, pre-polished finish, the series is offered in three task-specific variations:

  • #60 Grit: Ideal for fast, aggressive grinding, rapid stock removal, heavy edge shaping, and rough beveling.

  • #120 Grit: Perfect for general-purpose smoothing, removing saw marks, and cleaning up chipped tile edges.

  • #200 Grit: Optimized for fine refining, micro-finishing, and preparing tile edges for an immaculate, hone-finished display.

• Universal Angle Grinder Compatibility: Engineered with an industry-standard 22.23mm bore, allowing the wheel to drop directly onto the spindle flange of almost any standard 115mm or 125mm small angle grinder without needing specialized adapters.
