7” Flat Diamond Cup Wheel | 7/8 Inch Arbor

Professional 7” Flat Diamond Cup Wheel

This heavy-duty 7” flat diamond cup wheel is designed for controlled concrete grinding and surface preparation, especially when working on self-leveling material. Its flat cup design helps provide consistent surface contact and dependable cutting action, making it a reliable choice for contractors using hand grinders in demanding prep applications.

Key Features

• Flat cup design: Built for stable grinding performance and consistent surface contact during concrete preparation.
• Medium bond 30 grit: A versatile specification for grinding self-leveling material and general surface preparation tasks.
• 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 grinding self-leveling material, 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.
