Professional 7” Double Row Diamond Cup Wheel Economy

This 7” double row diamond cup wheel is a cost-effective option for contractors and operators who need dependable prep performance at a more economical price point. Its double row segment design provides consistent grinding action and solid surface contact, making it a practical choice for general concrete preparation with hand grinders.

Key Features

• Double row segment design: Built for consistent grinding performance and efficient material removal on concrete surfaces.
• Economy price point: A practical option for users who want reliable day-to-day prep performance while keeping tooling costs under control.
• Medium bond 30 grit: A versatile specification for general prep and surface preparation on a wide range of concrete slabs.
• 7/8 inch arbor: Made for compatible hand grinders using a standard 7/8” arbor setup for secure fitment.
• 7” diameter: Covers more surface area efficiently while maintaining control on hand-held grinders.

Applications

Suitable for general prep, concrete surface preparation, surface cleaning, and opening the concrete prior to coatings, overlays, 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.
