Arrow Segment Diamond Cup Wheel for Concrete & Coating Removal

1. Arrow Segment Diamond Cup Wheel – Aggressive Concrete Grinding & Surface Preparation

The ALSKAR DIAMOND Arrow Segment Diamond Cup Wheel is designed for construction contractors, concrete surface preparation specialists, and masonry professionals who require fast, effective material removal.

Featuring distinctive arrow-shaped diamond grinding segments, this cup wheel concentrates abrasive contact along the leading edges of the segments to support aggressive grinding and efficient stock removal.

The arrow segment geometry is particularly suitable for removing concrete surface irregularities, thin-set mortar, cementitious residue, and selected hard surface coatings.

Unlike densely arranged turbo grinding wheels designed primarily for controlled surface refinement, the Arrow Segment series focuses on rapid surface preparation and material removal.

Available in 4″, 4.5″, 5″, and 7″ diameters, this series provides practical options for localized repairs, concrete edges, and larger surface preparation applications.

With both 5/8″-11 threaded and 7/8″-5/8″ non-threaded arbor configurations, the ALSKAR Arrow Segment Cup Wheel can be selected for a range of compatible angle grinders.

2. Arrow-Shaped Diamond Segments for Fast Material Removal

The distinctive feature of the ALSKAR Arrow Segment Diamond Grinding Cup Wheel is its angular, arrow-shaped diamond segment geometry.

Each arrow segment forms a defined leading edge intended to concentrate grinding pressure on the working surface.

Aggressive Grinding Action

The arrow-shaped geometry is designed to engage concrete and cement-based materials efficiently, helping remove uneven surface layers and localized high spots.

Efficient Surface Preparation

The wheel is particularly useful during the early stages of surface preparation, when removing unwanted surface material is more important than achieving a fine decorative finish.

Open Segment Configuration

Wide spaces between adjacent arrow segments provide pathways for grinding debris to escape from the working area.

This open configuration can be helpful when removing cementitious residues and suitable hard coating materials.

5 mm Metal-Bonded Diamond Segments

The wheel features metal-bonded diamond grinding segments with a 5 mm abrasive height.

Segment dimensions and quantities vary according to wheel diameter, providing size-specific configurations for different grinding applications.

Durable Steel Cup Construction

The steel cup body provides structural support for the grinding segments, while circular openings in the body allow airflow and debris movement.

Together, these design features make the ALSKAR Arrow Segment series a practical solution for demanding concrete surface preparation tasks.

3. Applications & Recommended Materials

The ALSKAR Arrow Segment Diamond Grinding Cup Wheel is intended for aggressive grinding and surface preparation of concrete and cement-based materials.

• Follow the grinder and accessory manufacturers’ mounting instructions.

The correct arbor and wheel diameter are essential for safe operation and effective grinding performance.

6. Professional Grinding Performance & Safe Operation

The ALSKAR Arrow Segment Cup Wheel is intended for demanding grinding applications where concrete material must be removed efficiently before additional surface treatment.

Surface Preparation

The arrow-shaped grinding segments help remove uneven areas, hardened mortar, and selected residues from concrete surfaces.

Grinding Debris Clearance

The open spaces between arrow segments allow grinding debris to move away from the work area, helping maintain abrasive contact.

Dust Control

Grinding concrete and masonry can generate hazardous respirable crystalline silica dust.

Use appropriate dust shrouds, extraction systems, and respiratory protection in accordance with applicable regulations.

Wet & Dry Operating Conditions

Follow the specific wheel’s approved operating method.

For dry grinding, use compatible dust-control equipment. Wet grinding may only be performed when the wheel, grinder, and water-delivery equipment are approved for wet operation.

Safe Working Practices

Always use the proper guard, approved mounting hardware, and suitable personal protective equipment.

Never exceed the maximum rated RPM marked on the grinding wheel.

Stop immediately if the wheel becomes damaged or exhibits unusual vibration.
