Faithfull FAI1156SDG Depressed Centre Stone Grinding Disc 115 × 6 × 22 mm

This specialised depressed-centre grinding disc is crafted for efficient stock removal on stone, concrete and masonry surfaces. The 115 mm diameter and 22 mm bore ensure compatibility with standard 4½″ angle grinders, while the 6 mm thickness provides a robust platform for aggressive material removal with improved durability.

The depressed-centre shape allows the disc to present at an angle (typically around 45°) to the workpiece, offering enhanced access and control when grinding flat surfaces or removing cement mortar, paving, or tile adhesive. Engineered with a resin-bonded and fibreglass-reinforced matrix, this disc meets safety standards for abrasive wheels and is designed for grinding use only — not for slicing or cutting tasks.
