Double Row Segmented Diamond Cup Wheel for Concrete Grinding

1. Professional Concrete Grinding & Surface Preparation

The ALSKAR Double Row Segmented Diamond Cup Wheel is a professional grinding tool designed for concrete surface preparation, leveling, smoothing, and general masonry grinding.

Engineered with two staggered rows of diamond grinding segments, this cup wheel provides effective abrasive contact for removing surface irregularities, grinding down high spots, and preparing concrete substrates for subsequent finishing or coating applications.

The double-row configuration combines aggressive grinding capability with multiple working segments distributed around the wheel.

Available in 4″, 4.5″, 5″, and 7″ diameters, the series offers different configurations for professional contractors, concrete surface preparation specialists, and general construction applications.

2. Double Row Diamond Segment Technology

Staggered Double Row Design

The distinguishing feature of the ALSKAR Double Row Cup Wheel is its two-row segmented construction.

The inner and outer rows of curved diamond grinding segments are arranged in a staggered pattern to provide abrasive contact across the working surface.

Key Design Benefits

• Two rows of diamond grinding segments
• Staggered segment arrangement
• Multiple grinding contact points
• Curved segment geometry
• Metal cup body with ventilation openings
• Diameter-specific segment configurations

This design is suitable for general concrete grinding applications requiring both material removal and surface preparation.

Diamond Segment Construction

The wheel features diamond abrasive segments designed to grind concrete, mortar, masonry, and other compatible mineral-based materials.

Each size uses a specific segment configuration:

The larger 7-inch wheel uses longer segments and a higher segment count to provide grinding coverage appropriate for its diameter.

Ventilated Metal Cup Body

The metal cup body incorporates multiple openings around the center.

These openings provide space for airflow and grinding debris during operation.

Appropriate equipment guarding and dust extraction remain essential when grinding concrete or masonry materials.

3. Recommended Grinding Applications

Concrete Surface Grinding

Designed for grinding concrete floors, slabs, walls, and other accessible concrete surfaces.

The diamond segments remove surface material through abrasive grinding, making the wheel suitable for general concrete preparation.

Concrete Leveling

Useful for reducing localized high spots, uneven edges, and surface irregularities.

The tool can be used during preparation before resurfacing, coating, or repair work.

Mortar & Thinset Removal

Suitable for grinding residual mortar, thinset, and compatible cement-based adhesive materials from concrete and masonry surfaces.

For thick or highly elastic adhesive layers, a specialized PCD coating removal wheel may be more appropriate.

Masonry & Brick Grinding

Designed for suitable brick, concrete block, mortar, and other compatible masonry materials.

Edge Grinding & Surface Preparation

Useful for localized grinding, edge blending, and preparation of concrete surfaces before subsequent finishing operations.

Typical Working Environments

• Concrete floor renovation
• Residential construction and repair
• Commercial building refurbishment
• Warehouse floor preparation
• Masonry surface grinding
• Concrete repair and resurfacing
• Tile installation and renovation preparation

4. Double Row vs. Single Row Diamond Cup Wheels

Single Row Diamond Cup Wheels

Single-row cup wheels typically feature one row of grinding segments. They are commonly selected for applications where an aggressive grinding action is required.

Double Row Diamond Cup Wheels

Double-row cup wheels distribute abrasive contact across two rows of diamond segments.

This arrangement can provide more grinding contact points and help achieve a more consistent ground surface compared with certain single-row designs.

The appropriate configuration depends on the concrete condition, bond specification, grinder, and desired material removal rate.

5. Double Row Diamond Cup Wheel vs. PCD Cup Wheel

Diamond grinding cup wheels and PCD coating removal wheels serve different primary purposes.

Double Row Diamond Cup Wheel

Primarily designed for abrasive grinding of concrete, masonry, mortar, and compatible mineral-based materials.

It is suitable for leveling, smoothing, and preparing exposed concrete surfaces.

PCD Coating Removal Cup Wheel

Primarily designed for cutting and scraping bonded coatings, including compatible epoxy, glue, mastic, and certain resin-based materials.

For projects involving thick or tenacious coatings, a PCD tool may be preferred for initial stripping.

Once the coating is removed, a double-row diamond cup wheel can be used for subsequent concrete grinding and surface preparation.

6. Available Sizes & Arbor Connections

The ALSKAR Double Row Diamond Cup Wheel is available in four diameter options:

• 4 inches — 16 Diamond Segments
• 4.5 inches — 18 Diamond Segments
• 5 inches — 20 Diamond Segments
• 7 inches — 24 Diamond Segments

Arbor Options

Every diameter is available with:

• 5/8″-11 Threaded
• 7/8″-5/8″ Non-Threaded

Select the correct wheel diameter and mounting connection based on your grinding equipment.

For non-threaded configurations, verify the required mounting flanges and reducer bushing.

7. Equipment Compatibility & Operating Safety

Before using the wheel, verify that the selected diameter, arbor connection, mounting hardware, and operating speed are compatible with the grinder.

Operating Guidelines

• Use only with approved grinding equipment.
• Verify the maximum rated RPM for the selected wheel.
• Use a suitable wheel guard and dust extraction system.
• Wear appropriate eye, hearing, and respiratory protection.
• Inspect the wheel body and diamond segments before operation.
• Avoid excessive grinding pressure.
• Follow the approved operating method for the exact wheel model.
• Do not use damaged or improperly mounted grinding wheels.

Diamond cup wheels are intended for grinding, not for saw cutting or final decorative concrete polishing.
