Achieving clean, precise, and durable results when removing mortar, repairing expansion joints, or grooving concrete surfaces requires the right tool for the job. The GVHAKG Diamond Grinding Disc (125 mm x 6.35 mm x 22.23 mm) is engineered to meet the demands of both professional tradespeople and serious DIY homeowners. Combining robust construction, optimized diamond concentration, and versatile wet/dry operation, this disc delivers efficient material removal across a wide range of masonry applications.

Precision Technical Specifications

Designed with exacting standards, this diamond disc offers consistent performance job after job:

• Disc Diameter: 125 mm – ideal for standard angle grinders and dedicated joint cutters.

• Segment Width: 6.35 mm – perfectly suited for standard mortar joints, cracks, and paving gaps.

• Segment Height: 10 mm – provides ample working depth for thorough cleaning and grooving.

• Number of Segments: 9 – strategically arranged for smooth, vibration-reduced rotation.

• Arbor Size: 22.23 mm – compatible with the majority of power tools on the market.

Wide Range of Applied Materials

This 6.35 mm wide milling disc is built to tackle the toughest construction materials with ease. It is highly effective on:

• Concrete and reinforced concrete

• Blocks and bricks

• Mortar and cement-based renders

• Pavement stones and natural stone

• General masonry and plaster

Whether you are restoring old brickwork, preparing surfaces for repointing, or cutting channels for utilities, this disc provides the cutting aggression needed without excessive wear.

Superior Balance and Diamond Concentration

Performance is not just about sharpness – it is about stability and longevity. The GVHAKG 125 mm disc features a higher diamond concentration within each of its 9 segments. This advanced formulation ensures:

• Enhanced Cutting Speed: Removes material faster, reducing user fatigue and job time.

• Long Service Life: The dense diamond distribution extends the usable life of the disc, offering better value over time.

• Excellent Operational Balance: Precision-engineered segments minimize vibration, resulting in smoother handling and cleaner, more accurate grooves.

Versatile Operation – Wet or Dry

Flexibility on the job site is critical. This diamond grinding disc supports both dry and wet cutting methods, allowing you to adapt to site conditions, dust control requirements, and material hardness.

• Dry Cutting: Ideal for quick indoor or outdoor repairs when water access is limited. The segment design promotes efficient heat dissipation to prevent warping.

• Wet Cutting: Recommended for prolonged continuous use or when minimizing airborne dust is a priority. Wet cutting also extends the disc's lifespan by keeping the diamond segments cool.

This dual capability makes it the go-to choice for professional bricklayers and homeowners alike, enabling fast and efficient mortar removal, joint refurbishment, and concrete surface cleaning.

Broad Tool Compatibility

The 125 mm diamond milling disc is designed with universal application in mind. It is suitable for mounting on:

• Joint milling machines (joint rakes)

• Wall slotting machines and wall chasers

• Most standard 125 mm angle grinders (with 22.23 mm bore)

Before installation, always verify that your tool's maximum speed rating meets or exceeds the disc's operational specifications to ensure safe and optimal performance.
