Carbide is a type of high-speed steel that is commonly used in cutting tools, such as pencils, scissors, and other precision instruments. It has a hard, wear-resistant surface and can be sintered at high temperatures to create a strong bond. Carbide also has excellent corrosion resistance and can be formed into a variety of shapes and sizes.

On the other hand, high speed steel (HSS) is a different type of steel that is typically made from carbon or alloy steel. It is known for its strength and toughness, but it can also be prone to dulling and pitting if not properly sintered. HSS is often used in applications where high strength is needed, such as automotive parts or gears.
There are several key differences between carbide and HSS:
1. Composition: Carbide is primarily composed of carbon and rare earth elements, while HSS is made from carbon or alloy steel.
2. Wear resistance: Carbide has a harder, wear-resistant surface than HSS, which means it can last longer and be more durable.
3. Corrosion resistance: HSS may be more prone to corrosion than carbide, especially when exposed to moisture and oxygen. This can cause rust and scale buildup over time.
4. Shape and size: Carbide is typically available in a range of different grades and specifications, including fine, medium, and fine points. HSS, on the other hand, is usually made in a larger diameter and shape than carbide.
To determine whether you need carbide or HSS, consider the specific application and the level of wear and tear that you expect your tool to encounter. If you will be using your tool frequently and expect it to have a rough or aggressive working environment, you may want to choose carbide. If you anticipate your tool being used in a less demanding environment, such as in moderate manual tasks, HSS may be a better choice.

In summary, carbide and HSS are both types of high-speed steel with their own unique properties and uses. Understanding the differences between them is important for choosing the right tool for your specific needs.
