1. Professional Multi-Point PCD Cutting Technology
The ALSKAR Crushed PCD Diamond Cup Wheel is a professional surface preparation tool engineered for removing bonded coatings and adhesive residues from concrete floors.
Unlike conventional diamond grinding wheels, this specialized coating removal cup wheel features rectangular cutting segments embedded with irregular crushed polycrystalline diamond (PCD) chips.
The numerous exposed PCD cutting edges provide multiple points of contact with the coating material, creating an effective cutting and scraping action for stripping epoxy, paint, glue, mastic, and compatible floor coverings.
Available in 4″, 4.5″, 5″, and 7″ diameters, the series is designed to meet different coating removal and concrete floor preparation requirements.
2. Crushed PCD Chip Segment Technology
Multiple Cutting Points for Coating Removal
Each rectangular cutting segment contains exposed crushed PCD fragments that engage bonded coating materials during grinding.
Rather than relying on individual large PCD cutters, the crushed-chip configuration distributes cutting contact across numerous smaller diamond edges.
Key Design Features
- Irregular crushed PCD chips integrated into rectangular cutting segments
- Multiple exposed cutting edges for coating removal
- Metal cup body with ventilation and debris-clearance openings
- Segment configurations matched to wheel diameter
- Designed for professional concrete surface preparation
Rectangular PCD Segment Construction
The rectangular segment design provides an extended working surface containing multiple exposed PCD chips.
This configuration offers an alternative cutting pattern to conventional quarter-round PCD cup wheels and can be useful for contractors working with different coating types and substrate conditions.
The ideal PCD configuration depends on coating thickness, material characteristics, adhesion strength, equipment, and desired surface profile.
3. Available Sizes & PCD Segment Configurations
ALSKAR DIAMOND offers four diameter configurations:
| Diameter | Crushed PCD Segments | 4″ | 5 Segments | 4.5″ | 6 Segments | 5″ | 8 Segments | 7″ | 12 Segments |
|---|
Each diameter is available with the following mounting connections:
- 5/8″-11 Threaded
- 7/8″-5/8″ Non-Threaded
The number of rectangular PCD segments varies according to the wheel diameter.
Select the correct diameter and arbor connection based on your grinder specifications.
4. Recommended Applications
Epoxy Coating Removal
Designed for removing compatible epoxy coatings from concrete floors before recoating, repair, or resurfacing.
Glue & Adhesive Removal
Suitable for removing selected flooring adhesives and glue residues left after the removal of existing floor coverings.
Mastic Removal
The multiple crushed PCD cutting points can be useful for removing compatible mastic and tacky bonded materials.
Paint & Resin Coating Removal
Designed for removing suitable floor paints, resin coatings, and other bonded surface coverings.
Concrete Surface Preparation
Ideal for the initial coating removal stage of commercial and industrial floor renovation projects.
Typical Applications
- Warehouse floor renovation
- Industrial coating removal
- Commercial building refurbishment
- Epoxy floor replacement
- Flooring adhesive removal
- Concrete surface preparation before recoating
Actual coating removal performance depends on the material composition, thickness, bond strength, and condition of the concrete substrate.
5. Crushed PCD vs. Quarter-Round PCD Cup Wheels
Both crushed PCD and quarter-round PCD cup wheels are designed for coating removal, but their cutting structures differ.
Quarter-Round PCD Cup Wheels
Quarter-round PCD cup wheels feature individual, relatively large PCD cutting elements. These cutters provide concentrated cutting engagement and are commonly used for aggressive removal of difficult coatings and adhesives.
Crushed PCD Cup Wheels
Crushed PCD cup wheels feature numerous smaller PCD fragments embedded in rectangular cutting segments.
This design distributes cutting engagement across multiple exposed diamond edges, offering a different cutting contact pattern for coating removal.
Neither configuration is universally better for every application. Tool selection should be based on coating characteristics, substrate condition, equipment compatibility, and the required surface finish.
6. Surface Preparation & Finishing Considerations
PCD tools are designed primarily for stripping coatings, not for final concrete polishing.
Although crushed PCD cutting segments distribute contact across multiple edges, they may still scratch, groove, or leave a coarse texture on concrete surfaces.
Always perform a small test area before starting a complete coating removal project.
After stripping, additional diamond grinding or polishing may be required to achieve the desired surface profile for a new coating or flooring system.
7. Grinder Compatibility & Safety
Before installation, confirm the following:
- Correct cup wheel diameter
- Compatible spindle or arbor connection
- Proper mounting hardware
- Suitable wheel guard and equipment clearance
- Wheel maximum rated RPM
- Grinder rotation direction
- Approved wet or dry operating method
Use suitable dust extraction and personal protective equipment during coating removal and concrete surface preparation.
Inspect the PCD cutting segments and wheel body before every use. Do not operate damaged equipment or use a wheel beyond its maximum rated speed.
For existing flooring materials, identify potentially hazardous substances before disturbing the surface.
