5” Diamond Cup Wheel | 7/8 Inch Arbor (Black)

Professional 5” Diamond Cup Wheel

This heavy-duty 5” diamond cup wheel is built for aggressive concrete grinding, heavy-duty removal, and demanding surface preparation. Its compact cup design delivers strong cutting action, consistent surface contact, and reliable material removal, making it a practical choice for contractors using hand grinders where control and removal performance are important.

Key Features

• Segmented cup design: Built for dependable grinding performance and efficient material removal on concrete surfaces.
• Medium bond 16 grit: Designed for heavy-duty removal applications where a more aggressive cutting action is needed.
• 7/8 inch arbor: Made for compatible hand grinders using a standard 7/8” arbor setup for secure fitment.
• Heavy-duty steel body: Built for durability, balance, and dependable performance in demanding jobsite conditions.
• 5” diameter: Offers strong control and access for detailed grinding, edge work, and smaller surface areas.

Applications

Suitable for heavy-duty removal, aggressive concrete grinding, surface preparation, coating removal, and opening the concrete prior to overlays, coatings, or repair work.

How to Use

1. Choose the correct specification and diameter for your application.
2. Mount the cup wheel securely onto the grinder using the proper 7/8” arbor hardware.
3. Maintain a steady RPM and do not force the cup. Keep it moving in a smooth, consistent motion to avoid gouging the surface.
4. Ensure the grinder is in good condition. A clean, straight spindle and flange will reduce wobble and wear.

Tips & Tricks

• Inspect your grinder’s bearings, spindle, flange, and dust shroud. A bent spindle or dirty flange can cause wobble and uneven wear.
• If using with a dust shroud, make sure there’s only a small gap (around 1/8”) between the shroud and the floor for optimal vacuum suction.
• Follow up with a finer grit cup wheel for a smoother finish if needed.
