ValueMax 3-Piece Heavy Duty Cold Chisels Set - CRV Steel

The ValueMax chisels are crafted from high-quality CRV (Chrome Vanadium) steel, known for its durability and hardness.

The chisel blades have a hardness rating ranging from HRC 53-60, ensuring they can withstand significant force and maintain a sharp edge.

This set includes three cold chisels in sizes 10mm, 12mm, and 16mm.

Yes, these heavy-duty chisels are suitable for working with materials like concrete, masonry, and stone, as well as woodworking applications.

The handles are treated with a plastic coating to prevent oxidation and rust. Ensure the tool is kept dry for optimal preservation.

While heavy-duty, these chisels are best suited for precision cutting and shaping. For large-scale demolition, specialized tools might be more appropriate.

The tail end is annealed (softened) for added flexibility and to absorb shock, reducing the risk of the chisel splitting or fracturing under impact.

Ensure the cutting edge is sharp. Sharpen the chisel using a sharpening stone or file. Verify you are using the correct chisel size and type for the material.

Inspect the handle connection. If it's a plastic coating issue, it may indicate damage. For a securely fitted handle, ensure no debris is between the handle and the chisel body. If the handle is damaged, consider replacement.

Rust can form if the chisel is stored in a humid environment or not dried properly. Clean off rust with fine-grit sandpaper or a wire brush and dry immediately. Apply a light coat of oil to the blade for protection.
