Achieve Professional Polishing Results on Floors, Worktops & Decorative Stone

The Right Lines 180mm Diamond Polishing Discs are engineered for efficient polishing of stone, concrete, and terrazzo. Their larger 180mm diameter makes them ideal for use on 7-inch hand-held polishers and walk-behind floor polishers equipped with a grip (hook & loop) backing pad. They offer faster surface coverage compared to standard 100mm discs—saving time and delivering exceptional results on granite, marble, terrazzo, and polished concrete.

✅ Key Features:

• Large 180mm Diameter: Speeds up polishing on wider surfaces such as floors, worktops, patios, and wall claddings.

• Grip Backing: Compatible with most 180mm (7") hook backing pads on hand-held or floor polishers.

• Versatile Use: Suitable for polishing granite, marble, terrazzo, quartz, and exposed aggregate concrete.

• Dry or Wet Use: Designed for dry applications, but can be used wet for extended disc life where water use is appropriate.

• Efficient Progression: Choose from individual grades or a full 7-disc set to achieve your desired finish—from grind removal to mirror polish.

🧱 Applications:

• Polishing stone floors, edges, and small surface areas

• Restoring shine to granite and marble countertops

• Refinishing terrazzo and exposed aggregate concrete

• Removing light grind marks or scratches

• Achieving a satin to reflective gloss finish

📦 Available Grades:

• Grade 50: For initial surface leveling and removing grinding marks

• Grade 100 / 200 / 400 / 800 / 1500: For progressive refinement and scratch removal

• Grade 3000: For semi-reflective to high-gloss finish

Also available as a Complete 7-Disc Set (Grades 50–3000) for full polishing systems.

🔧 Technical Specifications:

• Disc Diameter: 180mm (7")

• Material: Diamond-impregnated bonded matrix

• Backing: Loop (Velcro®-style) for use with hook pads
