* Important Performance Reminder:

The “HRC55” workpiece hardness rating is based on standard machining parameters and recommended conditions.
In actual use, performance and tool life are affected by many factors, including:
- Workpiece material and hardness
- Cutting speed, feed rate, and depth of cut
- Coolant/lubrication method
- Machine tool rigidity and clamping stability

For optimal results, please consult our technical team for parameters tailored to your application before bulk production.

What are coated carbide inserts?

Coated carbide inserts have a layer of another material, such as titanium or aluminum oxide, to enhance their hardness and heat resistance.

Can carbide inserts be used for all materials?

While carbide inserts are versatile, they are not suitable for all materials. They work best with hard materials like steel and cast iron.

Can carbide inserts be sharpened?

Yes, carbide inserts can be sharpened, but it requires a special grinding wheel made of silicon carbide or diamond.

How do I choose the right carbide insert?

The choice of carbide insert depends on the material you’re working with, the type of cut you’re making, and the machine you’re using.

Can carbide inserts break?

While carbide inserts are extremely durable, they can break under excessive force or if used improperly.

How do I maintain my carbide inserts?

Regular cleaning and proper storage can help maintain the longevity of your carbide inserts. Also, avoid using them on inappropriate materials or at incorrect speeds.
