Frequently Asked Questions

Q1: What are tungsten carbide inserts used for?

A1: Tungsten carbide inserts are primarily used in CNC machining, turning, milling, and cutting applications. Their high wear resistance and toughness make them ideal for working with cast iron, steel, non-ferrous metals, and composite materials.

Q2: What material grades are available for these inserts?

A2: The available grades include C2, C5, ZK10UF, and ZK30UF. These provide different balances of hardness, impact resistance, and wear tolerance to suit a variety of industrial machining needs.

Q3: Which grade is best for rough turning and heavy-duty machining?

A3: The C5 uncoated grade is most suitable for rough turning, planing, and semi-finishing of carbon steel and alloy steel, thanks to its high strength and resistance to thermal shock.

Q4: Are these carbide inserts suitable for precision drilling?

A4: Yes. ZK10UF and ZK30UF are fine-grained tungsten carbide alloys that are specifically designed for high-precision applications such as hole machining and finishing of non-ferrous metals.

Q5: Can I order custom shapes or sizes of tungsten carbide inserts?

A5: Yes. FOTMA offers custom manufacturing of inserts based on client-provided specifications or drawings, ensuring the tools match your machining requirements perfectly.
