Diamond segmented grinding wheel MODECO 115 mm MN-78-132 for angle grinders

Diamond segmented grinding wheel MODECO 115 mm MN-78-132 for angle grinders is a replacement accessory designed for 115 mm (4.5") angle grinders. The wheel has a segmented diamond rim that enables efficient removal of concrete, masonry, natural stone and other hard materials while improving cooling and chip clearance during intensive grinding and shaping tasks. It is manufactured for use in construction, renovation and masonry applications where controlled material removal and durability are required.

Advantages

The segmented diamond rim provides rapid cutting and consistent performance on abrasive surfaces while segments promote air flow to reduce overheating. The wheel construction balances aggressive material removal with extended service life compared with non-diamond alternatives. Its 115 mm diameter and standardized arbor size make it compatible with most compact angle grinders, offering convenience for handheld grinding, chamfering and surface preparation.

Suitable for

• Grinding and shaping concrete and cement surfaces
• Removing mortar, plaster and thin layer coatings
• Profiling and smoothing natural stone and masonry
• Surface preparation before sealing or levelling

Key specifications

• Diameter: 115 mm (4.5")
• Design: segmented diamond rim for effective material removal and cooling
• Primary materials: concrete, masonry, stone and other hard building materials
• Intended use: handheld angle grinder operations
• Typical working tasks: grinding, shaping, profiling and removal of coatings or mortar

How to use

Install the wheel on a compatible 115 mm angle grinder following the grinder manufacturer's instructions and ensure the wheel is mounted securely with the correct flange. Always use appropriate personal protective equipment (eye protection, hearing protection, dust mask and gloves). Start the grinder at no-load speed to check for run-out and listen for unusual vibrations. Operate at recommended grinder speed and apply steady, moderate pressure; avoid forcing the wheel to prevent overheating or premature wear. Allow the wheel to cool periodically during extended use and clear accumulated debris from the work area.

Usage recommendations

Use water suppression only if the wheel and your grinder are rated for wet grinding; otherwise operate dry with adequate dust extraction. Match wheel speed and material hardness: for very abrasive concrete use shorter passes and frequent inspection of the rim. Replace the wheel when diamond segments are worn down to the safety line or when cracking, warping, or excessive vibration is observed.
