Product Description:

These sintered diamond floor grinding plates are professional-grade tools designed for high-efficiency floor grinding and polishing on concrete, terrazzo, epoxy, stone, and other hard floor surfaces.

With various shapes and sizes available, plus full customization options, these grinding plates deliver aggressive material removal, consistent finish, and long service life – making them ideal for both floor preparation (coating removal, leveling) and polishing (high-gloss finish).


Part 1: Sintered Diamond Technology – Why It Matters

Unlike electroplated or resin-bonded tools, sintered diamond has diamond grit distributed throughout the entire working layer.

 
 
Feature Sintered Diamond Advantage
Diamond throughout bond Fresh diamond exposed as tool wears – self-sharpening
Metal bond Strong grain retention, long life
High diamond concentration Aggressive cutting action
Wet or dry use Versatile for any job site
Can be dressed Renew cutting action when needed

Sintered vs. Other Floor Grinding Technologies:

 
 
Bond Type Life Cut Speed Best For Cost
Sintered (metal) ⭐⭐⭐⭐⭐ Long ⭐⭐⭐⭐ Fast Production grinding, hard concrete Moderate
Brazed ⭐⭐⭐⭐ Long ⭐⭐⭐⭐⭐ Fastest Aggressive removal Higher
Electroplated ⭐⭐ Short ⭐⭐⭐⭐ Fast Light duty, occasional Low
Resin bond ⭐⭐⭐ Moderate ⭐⭐⭐ Moderate Polishing, fine finishing Moderate

For floor grinding: Sintered metal bond offers the best balance of life, speed, and cost for most applications.


Part 2: Available Shapes – Why Different Shapes Matter

Different shapes provide different grinding characteristics. We offer:

Standard Shapes:

 
 
Shape Image Description Best For Characteristics
Round Circle / disc General purpose, even wear Smooth grinding, consistent finish
Square 4-sided block Aggressive grinding Sharp corners for faster cutting
Rectangular Long rectangle Large area coverage Efficient for wide floor grinders
Trapezoidal Wedge shape Edge work, corners Good for getting into tight spaces
Arrow Pointed triangle Aggressive cutting Maximum material removal
Double Arrow Two-pointed shape High efficiency Very aggressive, fast grinding
Horseshoe U-shape Coating removal Excellent for epoxy/paint removal

Shape Selection Guide:

 
 
Application Recommended Shape
Concrete grinding (general) Round, square, rectangular
Aggressive concrete removal Arrow, double arrow, trapezoidal
Epoxy/paint removal Horseshoe, trapezoidal
Terrazzo grinding Round, rectangular
Stone polishing Round, square
Edge work / corners Trapezoidal, small squares
Final polishing Round (for smooth finish)

Part 3: Available Sizes

 
 
Size (mm) Typical Use Grinder Compatibility
20mm Small grinders, detail work Edco, small planetary grinders
25mm Standard for many machines Most floor grinders
30mm Heavy grinding Lavina, Husqvarna, HTC
40mm Production grinding Large planetary grinders
50mm Maximum coverage Heavy-duty floor grinders
80-100mm Large single-plate grinders Walk-behind grinders

Other sizes available upon request.


Part 4: Grit Selection Guide

Floor grinding typically uses a progressive grit sequence – starting coarse and moving to fine.

 
 
Grit Cut Rate Finish Application
#16-30 Ultra-aggressive Very rough Heavy coating removal, concrete leveling, deep grinding
#30-60 Aggressive Rough General concrete grinding, surface prep
#60-120 Moderate Medium Smoothing, scratch removal
#120-200 Medium-fine Smooth Fine grinding, terrazzo grinding
#400-800 Fine Very smooth Pre-polishing, stone polishing
#1500-3000 Ultra-fine Mirror/high gloss Final polishing, high-gloss finish

Typical Floor Grinding Sequence:

 
 
Step Grit Passes Result
1 (Prep) #16-30 2-3 passes Remove coatings, flatten floor
2 (Grind) #30-60 2 passes Smooth surface, remove scratches
3 (Hone) #60-120 2 passes Fine surface, ready for polish
4 (Polish) #200-400 2 passes Satin/sheen finish
5 (Burnish) #800-3000 2 passes High-gloss, mirror finish

Part 8: How to Use

Step 1: Select Correct Plate

  • Choose shape based on application (arrow for aggressive, round for polishing)

  • Choose grit based on current floor condition

Step 2: Mount on Grinder

  • Attach plates to floor grinder using bolts or magnetic adapter

  • Ensure plates are secure and evenly spaced

Step 3: Select Speed & Pressure

 
 
Application Grinder Speed Pressure
Coarse grinding (#16-60) Low-medium (500-800 RPM) Heavy
Fine grinding (#60-200) Medium (800-1000 RPM) Moderate
Polishing (#400-3000) High (1000-1500 RPM) Light

Step 4: Grind Floor

  • Work in sections, overlapping passes

  • For wet grinding: use water to cool and control dust

  • For dry grinding: use dust extraction system

Step 5: Progress Through Grits

  • Always move to next finer grit only after all scratches from previous grit are removed

  • Clean floor between grit changes

Part 9: Dry vs. Wet Grinding

 
 
Factor Dry Grinding Wet Grinding
Dust High (requires dust extractor) None
Tool life Shorter 2-3x longer
Cut speed Good Faster
Convenience More convenient (no water) Requires water source
Surface finish Good Better
Best for Indoor with dust extraction Outdoor or controlled drainage areas

Recommendation: Use wet grinding for maximum tool life and fastest cutting. Use dry grinding with a quality dust extractor when water is not practical.
