Angle Grinder Cutting Discs: Materials, Applications, and Selection

Angle grinder cutting discs are indispensable tools in industrial processing, construction, and DIY projects. They come in various types based on material, application, and manufacturing process. This article provides a detailed classification of cutting discs and their applicable scenarios to help you choose the most suitable tool.

1. Classification by Material

Resin Cutting Discs (Grinding Wheels)

Resin cutting discs are mainly made of resin binders and abrasives (such as aluminum oxide and silicon carbide), offering high cutting power and wide applicability.

• Applicable Materials: Metal, stainless steel, stone, etc.
• Features:
  • Low cost and economical
  • Fast cutting speed and high sharpness
  • Wears out quickly, shorter lifespan

Diamond Cutting Discs

Diamond cutting discs embed diamond particles into a metal matrix, making them suitable for cutting high-hardness materials.

• Applicable Materials: Tiles, marble, concrete, glass, etc.
• Features:
  • Fast cutting speed, high wear resistance
  • High cutting precision, long service life
  • Relatively high cost

Alloy Cutting Discs (Tungsten Carbide Blades)

Alloy cutting discs, usually made of tungsten carbide, are designed for cutting softer materials.

• Applicable Materials: Wood, plastic, bamboo products, etc.
• Features:
  • High precision, smooth cutting without burrs
  • Suitable for high-speed cutting
  • Higher cost but very durable

2. Classification by Application

Metal Cutting Discs

• Primarily resin cutting discs, suitable for steel, stainless steel, aluminum, and other metals.
• Good cutting ability but wears out quickly.

Stone Cutting Discs

• Mainly diamond cutting discs, used for tiles, marble, granite, and other hard stones.
• Sharp cutting with minimal chipping.

Wood Cutting Discs

• Equipped with alloy blades, suitable for wood, bamboo, plastic, and similar materials.
• Fine cutting, ideal for woodworking.

Concrete/Brick Cutting Discs

• Primarily diamond saw blades, used for cutting concrete, bricks, asphalt, and other construction materials.
• Highly durable, ideal for heavy-duty applications.

3. Classification by Manufacturing Process

Sintered Diamond Cutting Discs

• Manufactured through high-temperature sintering, ensuring strong bonding, suitable for wet or dry cutting.
• Ideal for construction sites and stone processing.

Electroplated Diamond Cutting Discs

• Diamond particles are plated onto the blade surface via an electroplating process, making them suitable for precision cutting of glass, ceramics, and other brittle materials.
• Extremely high cutting accuracy, suitable for high-end applications.

Laser-Welded Diamond Cutting Discs

• Uses laser welding to bond the blade head to the base, making it resistant to high temperatures and heavy-duty cutting.
• Suitable for industrial-grade cutting with a long lifespan.

4. Classification by Edge Shape

Continuous Rim Cutting Discs (Smooth Edge)

• Suitable for tiles, glass, and other brittle materials, reducing chipping during cutting.
• Ideal for precision cutting applications.

Segmented Cutting Discs (Toothed, Wavy Edges)

• Suitable for high-hardness materials such as concrete and stone.
• Excellent heat dissipation and high cutting efficiency.

How to Choose the Right Cutting Disc?

When selecting an angle grinder cutting disc, consider the following factors:

1. Cutting Material: Different materials require specific disc types.
2. Cutting Needs: Whether you need high-speed cutting, precision cutting, or bulk processing.
3. Safety: Choose high-quality discs to prevent accidents caused by poor manufacturing.
4. Cost-Effectiveness: Select a product that meets your needs while offering the best value.

Summary

Angle grinder cutting discs come in many types, each with unique advantages and applications. Understanding the different materials, applications, and manufacturing processes can help you select the most suitable cutting disc, improving efficiency and extending tool life.
