What are the disadvantages of cemented carbide tools?

If you're in the machining industry, you've probably heard about cemented carbide tools. They're known for their durability, hardness, and resistance to wear and tear. However, like any other tool, they also have their downsides. In this article, we'll explore the disadvantages of cemented carbide tools.

1. Cost.

One of the biggest disadvantages of cemented carbide tools is their cost. These tools are more expensive than other types of cutting tools, which can be a significant drawback for businesses trying to cut costs. The initial investment in cemented carbide tools is higher, and they may not be the best option for smaller companies or those with limited budgets.

2. Brittle nature.

Cemented carbide tools are extremely hard, which makes them prone to brittleness. This means that they can easily break or chip if not handled with care. If a cemented carbide tool is dropped or used incorrectly, it can result in damage that renders the tool useless. This brittle nature can lead to frequent tool replacements, increasing maintenance costs.

3. Limited applications.

While cemented carbide tools are great for certain applications, they may not be suitable for all machining needs. These tools are best suited for high-speed cutting operations on hard materials like steel, stainless steel, and cast iron. They may not perform as well on softer materials or in applications where high temperatures are involved. This limitation can restrict the versatility of cemented carbide tools in certain industries.

4. Difficult to sharpen.

Unlike some other cutting tools that can be easily sharpened, cemented carbide tools are much harder to sharpen. Once the cutting edge becomes dull, it may need to be replaced rather than sharpened, adding to the overall cost of using these tools. This can be a hassle for businesses that rely on sharp tools for their daily operations.

5. Environmental impact.

Cemented carbide tools contain tungsten carbide, which is a heavy metal and can have negative environmental impacts if not disposed of properly. In addition, the manufacturing process of cemented carbide tools can produce harmful emissions and waste. As sustainability becomes more important in today's world, businesses may need to consider the environmental impact of using these tools.

Overall, while cemented carbide tools have many advantages, it's important to be aware of their disadvantages as well. The high cost, brittleness, limited applications, difficulty in sharpening, and environmental impact are all factors to consider when choosing cutting tools for your business.
