Diamond Grinding Disc MAR-POL 125 mm for Concrete, M14, 2 Segments (M08787)

Diamond Grinding Disc MAR-POL 125 mm for Concrete, M14, 2 Segments is a cutting tool designed for use with 125 mm angle grinders that accept an M14 arbor. The disc features two segmented diamond cutting segments specifically shaped for grinding, smoothing and leveling concrete surfaces. It is intended for material removal, preparing rough concrete for coatings or further finishing, and for light to medium concrete repair tasks.

Advantages

The segmented diamond design ensures efficient debris removal and faster material cut, while the diamond abrasive provides consistent wear resistance and long life during surface grinding. The M14 threaded arbor makes attachment to a wide range of angle grinders quick and secure. The disc’s geometry is balanced for steady operation and reduced vibration, helping to maintain surface flatness and operator control during use.

Suitable for

• Grinding and leveling concrete floors and slabs
• Surface preparation before applying coatings, adhesives or sealants
• Removing surface irregularities, laitance and thin layers of screed
• Concrete repair and renovation tasks requiring controlled material removal

Key specifications

• Diameter: 125 mm
• Arbor thread: M14
• Segment type: 2 segmented diamond segments
• Intended material: concrete
• Tool compatibility: angle grinders designed for 125 mm discs

How to use

Mount the disc securely on an angle grinder with an M14 arbor following the tool manufacturer’s instructions and ensure the grinder is unplugged or battery removed while fitting. Use appropriate protective equipment such as eye protection, dust mask or respirator, hearing protection and gloves. Start the grinder and make steady passes across the concrete surface at a controlled speed, avoiding excessive pressure which can reduce segment life and cause uneven grinding. Allow the diamond segments to do the work, and periodically inspect the disc and work surface for progress and wear.

Usage recommendations

For best results, use with a dust extraction system or work in well-ventilated conditions to limit airborne concrete dust. Select an angle grinder with appropriate power for steady operation and follow safety guidelines for abrasive tools. Replace the disc when cutting efficiency noticeably decreases or if segments show significant wear or damage.
