Diamond polishing disc Distar 100 mm P30 for grinding and polishing stone and concrete

Diamond polishing disc Distar Ø100 mm, grit P30, designed for mechanical grinding and polishing of natural stone, engineered stone and concrete surfaces. The disc has a diamond abrasive layer that provides effective material removal and surface preparation. It is intended for use with angle grinders and polishing machines that accept a 100 mm sanding/polishing accessory and is suitable for the coarse grinding stage prior to finer polishing.

Advantages

The diamond abrasive composition ensures fast stock removal and consistent wear across the working surface, while the P30 grit provides coarse cutting for leveling and smoothing. The 100 mm diameter offers control and access in confined areas and along edges. The disc construction balances aggressive grinding performance with predictable life span, making it suitable for both single-site corrections and larger surface preparation tasks.

Suitable for

• Removing unevenness and high spots on natural stone and engineered stone
• Coarse grinding of concrete floors and small concrete elements
• Preparing surfaces before switching to finer diamond pads or polishing compounds
• Edge and detail work where a smaller diameter disc is needed

Key specifications

• Diameter: 100 mm
• Abrasive type: diamond layer
• Grit size: P30 (coarse)
• Intended materials: natural stone, engineered stone, concrete
• Typical applications: grinding, leveling, surface preparation

How to use

Mount the Distar 100 mm P30 diamond polishing disc on a compatible angle grinder or polishing machine following the tool manufacturer’s mounting instructions. Operate at the recommended speed for diamond discs and apply light, even pressure to avoid gouging. Move the disc across the surface in overlapping passes to achieve uniform removal; keep the tool moving to prevent overheating and uneven wear. For dry grinding ensure appropriate dust extraction; for wet grinding use a controlled water feed if the disc and machine support wet operation.

Usage recommendations

Begin with the P30 disc for coarse leveling, then progress through finer grits to achieve the desired finish. Use personal protective equipment, ensure adequate ventilation or dust extraction, and follow the grinder manufacturer’s safety guidelines. Inspect the disc before each use and replace it when diamond segments are worn or the disc no longer cuts effectively.
