Lathe Cutting Tools are tools mounted on a lathe (wood/hand/CNC) and used to produce turned parts. They move along the axis of the lathe and their path determines the final shape of the workpiece.

There are several non-CNC and CNC lathes, each type with unique features and designs that determine the supported lathe cutting operation and outright applications. As a result, choosing the right cutting tool requires a thorough understanding of the tool. This article discusses common lathe tools, their design, features and applications. Let’s get straight to the point.

Four Categories: Types of Lathe Cutting Tools

Lathe cutting tools can be classified into four main categories based on different criteria:

1: Lathe Cutting Tools Based on Material

  1. High-Speed Steel (HSS) Tools:
    • Characteristics: Durable and versatile, HSS tools maintain sharpness and resist heat. They are suitable for a wide range of materials and are generally used for roughing and finishing operations.
    • Applications: Commonly used for general turning, especially in smaller workshops.
  2. Carbide Tools:
    • Characteristics: Carbide tools offer superior hardness and wear resistance compared to HSS. They can handle high-speed cutting and maintain sharp edges for longer periods.
    • Applications: Ideal for high-precision work and for cutting harder materials.
  3. Cermet Tools:
    • Characteristics: Made from a blend of ceramic and metal, cermet tools combine the hardness of ceramics with the toughness of metals. They provide excellent surface finishes and longer tool life.
    • Applications: Used for high-speed machining of difficult materials and for finishing operations.

2: Lathe Cutting Tools Based on Operations

  1. Turning Tools:
    • Characteristics: Designed for cutting and shaping cylindrical parts. These tools include roughing tools for material removal and finishing tools for achieving smooth surfaces.
    • Applications: Suitable for general turning operations.
  2. Facing Tools:
    • Characteristics: Used to machine the surface of a workpiece perpendicular to its axis. Facing tools help in achieving a flat surface and precise dimensions.
    • Applications: Essential for creating a flat surface on a cylindrical workpiece.
  3. Parting Tools:
    • Characteristics: Also known as cutoff tools, parting tools are used to cut off or separate a portion of the workpiece. They have a narrow, wedge-shaped blade.
    • Applications: Commonly used for slicing material and making grooves.
  4. Boring Tools:
    • Characteristics: Used to enlarge and finish holes that have already been drilled. Boring tools achieve precise dimensions and smooth finishes.
    • Applications: Ideal for internal machining and fine adjustments to hole diameters.

3: Lathe Cutting Tools Based on Structure

  1. Single-Point Tools:
    • Characteristics: Feature a single cutting edge and are versatile in various turning operations. The cutting point can be customized for different tasks.
    • Applications: Common in turning, facing, and threading operations.
  2. Multi-Point Tools:
    • Characteristics: They have multiple cutting edges and are designed to remove material efficiently. Use them for operations that require high material removal rates.
    • Applications: Useful for milling and drilling operations.
  3. Indexable Tools:
    • Characteristics: Feature cutting inserts that you can rotate or replace as they wear.out. This design improves tool life and reduces downtime.
    • Applications: Ideal for high-production environments where tool changes need to be quick and efficient.

4: Lathe Cutting Tools Based on Feed Direction

  1. Radial Feed Tools:
    • Characteristics: Cut material from the outer diameter towards the center, typically used in turning operations.
    • Applications: Suitable for operations where the cutting action moves radially inward.
  2. Axial Feed Tools:
    • Characteristics: Move parallel to the axis of the workpiece. Use these tools for operations where the cutting action advances along the length of the material.
    • Applications: Ideal for facing, turning, and grooving operations.

How to Select the Right Lathe Cutting Tool?

Selecting the right lathe cutting tool involves considering several factors:

  1. Material of the Workpiece: Choose a tool material that can handle the hardness and characteristics of the workpiece material.
  2. Type of Operation: Match the tool type with the specific operation required, whether it’s turning, facing, parting, or boring.
  3. Desired Surface Finish: For high-quality surface finishes, select tools with finer cutting edges and appropriate coatings.
  4. Tool Life and Cost: Evaluate the cost of tools relative to their lifespan and performance to ensure a balance between efficiency and budget.
  5. Machine Compatibility: Make sure the tool fits the lathe machine’s specifications and mounts and adjusts properly.
