How to choose high-performance carbide cutting inserts and tools

In the fields of metal processing, mold manufacturing and precision parts production, carbide cutting tool inserts have become an indispensable core tool in modern industry due to their excellent wear resistance, impact resistance and long life.

However, facing the numerous brands and models on the market, how to choose carbide cutting tool insert manufacturers, suitable carbide inserts for cutting tools, and flexible and efficient replaceable insert slotting tools

We will provide you with practical suggestions and recommendations.

一. The world’s leading carbide cutting tool insert manufacturer

1. Sandvik Coromant

As a global leader in carbide tools, Sandvik offers a full range of indexable inserts (such as CNMG, TNMG models) for turning, milling and drilling. Its CVD/PVD coating technology significantly improves insert life.

2. Kennametal

Kennametal’s Beyond™ series of carbide inserts are known for their high precision, especially for stainless steel and high-temperature alloy processing. Its chip breaker design can reduce built-up edge problems.

3. Puwei

The Puwei series inserts feature innovative geometric structures, suitable for deep groove processing and heavy-duty cutting, and are ideal partners for replaceable insert slotting tools.

二. The world’s leading manufacturer of cemented carbide cutting tool inserts

The performance of cemented carbide inserts depends on the base material, coating technology and geometric design. The following are common classifications and typical application scenarios:

1. Classification by processing type

Turning inserts (such as CNMG120408): strong versatility, suitable for external cylindrical and end turning.

Milling inserts (such as APKT1604): used for plane milling and copy milling, need to pay attention to edge strength and heat dissipation.

Drilling inserts (such as TCMT): suitable for deep hole drilling, need to optimize chip removal ability.

2. Selection by coating technology

TiAlN coating: excellent high temperature resistance, suitable for high-speed processing.

AlCrN coating: strong anti-adhesion, recommended for sticky materials (such as aluminum alloy).

Uncoated inserts: economical choice, suitable for short-chip materials such as cast iron.

3. Indexable Inserts Recommendation

CNMG120408-MF5: multi-edge design, compatible with rough machining and semi-finishing of steel parts.

DNMG\DCMT070202: Sharp cutting edge optimized for stainless steel, reducing cutting force. Ultra-fine particle matrix, taking into account both wear resistance and toughness.

Whether it is batch production or complex parts processing, choosing the right carbide cutting tool insert manufacturer, suitable insert model and flexible replaceable insert grooving tool can help you significantly improve efficiency, reduce costs and extend tool life.
