3 Inch Grinding Disc Compatible with HTC Grinders

The Grinding Disc is engineered for fast, consistent concrete grinding and long service life. Featuring 10 premium diamond segments with an 8 mm segment height, this grinding disc provides excellent grinding efficiency, stable performance, and even wear. It is ideal for concrete surface preparation, floor leveling, coating removal, and terrazzo grinding.

Designed for professional contractors, this 3-inch grinding disc is compatible with HTC floor grinders and delivers reliable performance on both residential and commercial flooring projects.

Grit Options

Our grinding discs are available in a wide range of grit sizes to suit every stage of concrete grinding and polishing.

Available grits include 6#, 16/20#, 16#, 20#, 25#, 30#, 30/40#, 50#, 60#, 60/80#, 70#, 80#, 80/100#, 100#, 100/120#, 120#, 150#, and 200#.

Lower grit numbers (6#–30#) provide aggressive grinding and fast material removal, making them ideal for coating removal and initial surface preparation. Higher grit numbers (50#–200#) produce a finer scratch pattern, creating a smoother surface and preparing the floor for polishing.Please contact us if you have question with grit numbers.

Bond Options Based on Concrete Hardness

Selecting the correct bond is essential for achieving maximum grinding efficiency and extending tool life.

  • Soft bonds are recommended for hard concrete because they wear faster, continuously exposing fresh diamonds.
  • Hard bonds are best for soft concrete, preventing the diamonds from wearing away too quickly.
  • Medium bonds are suitable for most general-purpose concrete applications.

Please choose the appropriate bond according to the concrete hardness chart below for the best grinding performance. Contact us if you have question with bond options.

If duties are required, the courier company will contact you directly and assist with the payment and processing.
  3. How to measure concrete floor hardness?
    Rebound test for PSI hardnessA rebound test (Schmidt Hammer test) is a quick, non-destructive method to estimate the compressive strength (PSI) and surface hardness of a concrete floor.
    Scratch test for Mohs scaleThe Mohs hardness test measures how resistant concrete is to scratching by using tools with known hardness levels. A test pick is dragged across the concrete surface, and the scratch is inspected. The highest-numbered pick that can scratch the surface represents the concrete’s surface hardness. Mohs scale ranges from 1 (soft) to 10 (hard).
