Yes, carbide end mills can be re-sharpened, but it's best done by professionals to maintain proper angles and cutting edges.

Yes, coatings like TiN, TiAlN, AlTiN, and DLC can improve wear resistance, reduce friction, and enhance heat resistance.

● Choose the right tool for the job.

● Use recommended cutting speeds and feeds.

● Apply proper coolant.

● Inspect and replace worn tools regularly.

● Store tools in a dry, clean environment.

Carbide end mills offer higher cutting speeds, longer tool life, better surface finishes, and greater heat resistance compared to high-speed steel tools.

Consider the material you're machining, the type of milling operation (slotting, contouring, profiling), tool dimensions (diameter, length, shank size), and any specific coatings needed (e.g., TiN, TiAlN).

Carbide end mills are made from carbide and cobalt, offering high wear resistance and speed. Tungsten carbide milling tools are specifically made from tungsten carbide, known for extreme hardness and heat resistance.
