What is a Crack Chasing Blade?

A crack chasing blade for angle grinder is designed specifically for widening and deepening cracks in concrete, brick, or masonry. Unlike standard cutting blades, these blades feature a segmented design that allows for precise control over the cutting depth while minimizing the risk of damaging surrounding surfaces.

Features of Crack Chasing Blades

  • Segmented Design: Allows for efficient cutting and prevents the blade from binding.
  • Depth Control: Helps you target specific depths to ensure a clean repair job.
  • Durability: Made from high-quality materials to withstand intense grinding and cutting.
  • Versatility: Suitable for various materials including concrete, brick, and stone.

Choosing the Right Crack Chasing Blade

Blade Material

Blades are generally made from different materials, each designed for specific applications. Here are the most common types:

  • Diamond Blades: These are the most effective and durable, but they can be pricier. Ideal for professional use.
  • Tungsten Carbide Blades: A more affordable option that's suitable for less intensive jobs.

Blade Size

You’ll also want to consider the size of the blade. Common diameters include 4.5”, 5”, and 7”, and the choice often depends on the size of the angle grinder and the intended application.

Number of Segments

More segments can mean smoother cuts, but it may take longer to complete the job. Fewer segments will enable faster cutting but might leave a rougher finish.

Tips for Using Crack Chasing Blades Effectively

  1. Safety First: Always wear appropriate protective gear, including goggles, gloves, and a dust mask.
  2. Prepare Your Surface: Clean the area around the crack to remove debris and dust, which ensures better visibility and cleaner cutting.
  3. Proper Technique:
    • Use a steady, even pressure.
    • Allow the blade to do the work; forcing it may lead to unwanted damage and a rough cut.
  4. Cooling Breaks: Give your blade time to cool down to prevent overheating, which can shorten its lifespan.

Common Issues and Solutions

  • Blade Binding: This usually happens when excessive pressure is applied. Relieve pressure and adjust your angle as needed.
  • Uneven Cuts: Inconsistent speed can cause uneven cutting. Maintain a constant speed for the best results.
  • Chipping: To avoid chipping on the edges of your cuts, consider making shallow passes first and gradually deepening them.

Maintenance of Crack Chasing Blades

To prolong the life of your crack chasing blade for angle grinder, proper maintenance is essential:

  • Clean Regularly: Remove dust and debris after each use.
  • Inspect for Damage: Check for wear and tear, replacing the blade if there are significant damages or dullness.
  • Store Properly: Keep the blade in a dry place to prevent rust and corrosion.
