Professional 7” S Style Diamond Cup Wheel

This heavy-duty 7” S style diamond cup wheel is built for aggressive concrete grinding, adhesive removal, and demanding surface preparation. Its S-style segment design delivers strong cutting action and fast stock removal, making it a reliable choice for contractors using hand grinders on concrete surfaces where tough removal performance is needed.

Key Features

• S-style segment design: Built for aggressive grinding performance and efficient material removal on concrete surfaces.
• Soft bond 16 grit: Designed for aggressive grinding and adhesive removal applications where fast 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.
• 7” diameter: Covers more surface area efficiently while maintaining control on hand-held grinders.

Applications

Suitable for aggressive grinding, adhesive removal, 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.
