Grooving Inserts

Introduction to Grooving Inserts

Grooving Inserts are specialized carbide cutting tools designed for machining grooves, slots, and parting-off operations on CNC lathes and milling machines. These inserts provide high precision, excellent surface finish, and long tool life, making them essential for industries like automotive, aerospace, oil & gas, and general engineering.

At CNC Tools Depot, we stock a wide range of grooving inserts from leading global brands including Kennametal, Widia, Korloy, Taegutec, Seco, Mitsubishi, and more – ensuring you always get the right tool for your application.


Applications of Grooving Inserts

Grooving inserts are versatile and widely used in CNC machining for:

  • Internal Grooving – creating precise grooves inside a bore.

  • External Grooving – machining slots and reliefs on outer diameters.

  • Parting-off / Cut-off – separating a finished component from the bar stock.

  • Face Grooving – producing circular grooves on the face of a component.

  • Thread Grooving – machining grooves for threading applications.

  • Custom Grooving – specialized grooves for sealing, O-rings, or snap-fit designs.


Types of Grooving Inserts

Different geometries and styles of grooving inserts are available to suit specific machining requirements:

  1. External Grooving Inserts – Ideal for turning grooves on OD surfaces.

  2. Internal Grooving Inserts – Designed for boring bars to machine internal slots.

  3. Face Grooving Inserts – Used to cut circular grooves on component faces.

  4. Parting Inserts – Specialized inserts for efficient and burr-free cut-off.

  5. Full Radius Grooving Inserts – For forming rounded or profile grooves.

  6. Thread Grooving Inserts – For preparing thread relief grooves.

  7. Custom Geometry Inserts – Tailored for industry-specific requirements.
