Indexable Inserts
In machining processes such as drilling, turning, and milling, cutting tools—like turning tools and cutting inserts—are responsible for removing material from the workpiece. Indexable inserts used for turning and milling components typically have multiple cutting edges and are screwed or clamped into toolholders such as turning toolholders and milling cutters. Their efficiency depends heavily on the selected cutting speed, which is crucial for the effective machining of metals and other materials.
Benefits of using indexable inserts:
- Flexibility: Insert types and geometries can be matched to the specific task.
- Cost savings: The toolholder is reusable; only the insert is replaced.
- High-performance machining: Suitable for high cutting speeds and heavy material removal.
- Precision: Ideal for applications with tight tolerance requirements.

Applications and Use Cases for Indexable Inserts
Indexable inserts are used across a wide range of metal-cutting operations. Their flexibility and the ability to swap worn edges quickly make them a cornerstone of modern machining.
Turning
-
Longitudinal turning: Reducing the workpiece diameter along its axis.
-
Facing: Machining the end face of a workpiece.
-
Roughing: Removing large volumes of material; requires tougher insert geometries.
-
Finishing: Achieving precise dimensions and fine surface quality.
-
Thread turning: Specialized geometries for internal and external threads.
Milling
-
Face milling: Producing flat surfaces.
-
Shoulder (corner) milling: Accurately machining edges and corners.
-
Slotting: Cutting keyways, slots, or grooves.
-
Roughing & finishing: From high material removal to fine surface finishing.
Drilling
-
Boring: Enlarging existing holes.
-
Deep-hole drilling: Creating holes with high depth-to-diameter ratios.
-
Step drilling: Producing holes with multiple diameters.
Threading
-
Thread turning: Producing external threads.
-
Thread milling: Producing internal or external threads on complex parts.
-
Thread taps with indexable inserts: For larger diameters or difficult materials.
Heavy-duty machining
-
Large components: Rolls, turbine parts, and gearbox components.
-
High-temperature / high-strength alloys: Such as hardened steels or nickel-based superalloys.
Machining difficult materials
-
Titanium alloys: Common in aerospace.
-
Nickel-based alloys: Turbine blades and energy-sector components.
-
Hardened steels: Automotive and tooling applications.
Non-ferrous metals and plastics
-
Aluminium: Inserts with dedicated chipbreakers for chip control.
-
Copper: Often uncoated or specially tailored substrates.
-
Plastics: Precision parts, frequently using polished geometries.
Cast irons
-
Gray cast iron (GG): High material removal rates are feasible.
-
Ductile iron (SG/DI): Requires tougher cutting materials due to higher ductility.
Surface finishing
-
High-gloss machining: Specialized cutting edges for polished finishes.
-
Fine finishing: Tight tolerances with low surface roughness.
Special applications
-
Round inserts: For blending and complex contours.
-
Profile tools: For producing specialized profiles (e.g., turbine airfoils).
-
Weld prep: Milling chamfers and weld bevels.
Choosing the Right Insert: Shape, Edge Length, and Tolerances
Select the proper insert for your application using the ISO designation shown in our online shop. The ISO code conveys tolerances, cutting and clamping features, insert shape, hand of cut, and cutting-edge length. As a rule, the tool material must be harder than the workpiece (e.g., steel).
Depending on the workpiece and operation, the insert is positioned in the toolholder to achieve the required relief angle.
-
Positive inserts have a relief angle > 0°.
-
Negative inserts have a relief angle of 0°.
Why Indexable Inserts?
Indexable inserts offer clear advantages over solid or brazed tools:
-
Multiple edges: When an edge wears, rotate (index) the insert and keep running; replace only the insert, not the entire tool.
-
Lower operating cost: Reduce tool spend by ordering replacement inserts instead of new tool bodies.
-
Reliable chip control: Engineered chipbreakers create short, manageable chips—improving evacuation and reducing risk of tool, part, or operator damage.
