Material & Durability of Insert Chips

Insert chips are essential cutting tools in modern machining operations, and their performance is heavily influenced by the materials used in their construction. The most common material is cemented carbide, but alternatives such as ceramic, cermet, high-speed steel (HSS), and coated variants offer specialized benefits for different applications. Selecting the right material directly impacts tool life, cutting efficiency, surface finish quality, and suitability for specific workpiece materials.

Common Materials Used in Insert Chips

Cemented Carbide

Cemented carbide is the most widely used material for insert chips due to its excellent balance of hardness, toughness, and wear resistance. It is composed of fine tungsten carbide (WC) particles bonded with a metallic binder, typically cobalt. This microstructure provides exceptional resistance to abrasion and deformation under high mechanical stress.

These inserts excel in machining ferrous and non-ferrous metals, maintaining a sharp cutting edge over extended periods. Their durability makes them ideal for high-volume industrial applications such as turning, milling, and drilling. Additionally, cemented carbide inserts can be optimized through different grain sizes and cobalt content to suit specific cutting conditions—finer grains increase hardness, while higher cobalt levels improve toughness.

Ceramic

Ceramic insert chips are primarily made from aluminum oxide (Al₂O₃) or silicon nitride (Si₃N₄), offering extreme hardness and outstanding thermal stability. Unlike metal-based tools, ceramics retain their hardness even at temperatures exceeding 1,200°C, making them perfect for high-speed dry cutting operations where coolant use is limited or avoided.

They are especially effective for machining hardened steels, cast irons, and superalloys—materials that generate intense heat during cutting. While ceramics are more brittle than carbide, their ability to withstand thermal shock and resist wear at elevated temperatures allows for faster cutting speeds and longer tool life in appropriate applications. However, they are not recommended for interrupted cuts or operations with vibration due to their low impact resistance.

Cermet

Cermet (a portmanteau of "ceramic" and "metal") combines the best properties of both material types. Typically composed of titanium-based compounds (like titanium carbonitride) bonded with metallic elements such as nickel or molybdenum, cermet inserts offer high hardness, excellent wear resistance, and good thermal stability.

They are particularly effective in precision finishing operations on steel and stainless steel, delivering superior surface finishes and consistent dimensional accuracy. Cermet inserts also exhibit strong resistance to built-up edge formation, a common issue when machining sticky materials. While not as tough as carbide, they outperform it in continuous high-speed cutting scenarios where edge retention and smooth finishes are critical.

High-Speed Steel (HSS)

Though less common in modern indexable insert applications, high-speed steel is still used in certain specialized or economical tooling setups. HSS contains alloying elements like tungsten, molybdenum, vanadium, and chromium, which enhance its hardness and heat resistance up to approximately 600°C.

These inserts offer excellent toughness and are more forgiving in applications involving variable cutting depths, interrupted cuts, or unstable setups. Their ability to be resharpened multiple times makes them cost-effective for low-volume or general-purpose machining tasks. However, they wear faster than carbide or ceramic inserts and are generally limited to lower cutting speeds, making them less suitable for high-efficiency production environments.

Coated Insert Chips

While many inserts are used in their uncoated form, advanced applications often require coated variants to enhance performance. Coatings such as titanium nitride (TiN), titanium carbonitride (TiCN), aluminum oxide (Al₂O₃), and diamond-like carbon (DLC) are applied using physical vapor deposition (PVD) or chemical vapor deposition (CVD) techniques.

These coatings significantly improve wear resistance, reduce friction between the tool and workpiece, and act as a thermal barrier, protecting the base material from heat damage. For example, TiN-coated inserts have a golden hue and offer improved lubricity and oxidation resistance, extending tool life by up to 300% in some cases. Multi-layer coatings are increasingly common, combining hardness, toughness, and thermal protection for optimal performance across diverse materials—including stainless steel, titanium, and abrasive composites.
