4 Inch Diamond Grinding Cup Wheel LDEXIN Grit Disc for Marble Granite

Description

Product Overview

The LDEXIN 4 Inch Diamond Grinding Cup Wheel is engineered for demanding industrial applications where precision and durability are paramount. Constructed with a high‑concentration diamond grit #30 brazed onto a robust metal core, this cup wheel offers aggressive material removal while maintaining a smooth finish. The disc measures 100 mm (4 inches) in diameter with a 16 mm (5/8 inches) arbor bore, making it compatible with a wide range of grinding machines. Weighing just 3.21 oz, the wheel balances lightweight handling with the strength needed to cut through granite, marble, steel, iron, and masonry. Its design promotes efficient heat dissipation, especially when used with water cooling, extending the wheel’s service life and reducing wear.

Key specifications include a 30‑grit diamond concentration that ensures rapid cutting action, a brazed bond that secures the diamonds firmly to the wheel, and a versatile bore size that fits standard 5/8 inches arbors. The product is packaged as a single 4 inch disc, identified by model JJ001280, and meets rigorous industry standards for safety and performance.

Usage

This cup wheel excels in both wet and dry grinding scenarios. In wet applications, the water coolant reduces friction, prevents overheating, and minimizes dust, making it ideal for indoor environments and for cutting delicate materials like porcelain tiles or glass. Dry grinding is suitable for outdoor or high‑temperature tasks where water is impractical. The wheel’s aggressive 30‑grit profile is perfect for shaping, profiling, and removing excess material from stone countertops, concrete slabs, and metal components. Professionals such as stone fabricators, metalworkers, and construction crews will find the wheel’s reliability and speed valuable for meeting tight project deadlines.

Because the wheel is designed for a 5/8 inches arbor, it fits most standard bench grinders, angle grinders, and portable rotary tools. Users should always secure the wheel firmly, verify the machine’s RPM does not exceed the wheel’s rating, and employ appropriate personal protective equipment, including eye protection and hearing protection.
