What Are the Different Types of Cutting Tools On a CNC Lathe?
What Are the Different Types of Cutting Tools On a CNC Lathe? Lathe cutting tools are pivotal parts of Turning machining China Inc.’s CNC machining services. In our CNC turning process, cutting tools are mounted on a lathe, move along the lathe’s axis, and their paths – programmed via CAD and CAM software inputted by our machinists – determine the workpiece’s final shape. Extremely accurate, we use our CNC lathes to turn out thousands of identical components for our clients in a variety of industries across the country.

CNC Lathe Cutting Tools: What Are the Common Lathe Operations?
There are different lathe cutting operations we use to get your part’s desired size and shape. These are the basic operations we utilize depending on the specifications of your CNC machining project:
- Facing: The first step in most lathe operations. It involves cutting the metal from an end to make it fit at the right angle of the axis.
- Tapering: This operation involves cutting metal to a cone shape using a compound slide. Depending on your job’s requirement, we can change the angle by adjusting the compound slide.
- Parallel Turning: This involves cutting a material parallel to the axis. It is an important operation used for decreasing the diameter of the material.
- Parting: Parting is the removal of a part so that it faces the end. It involves using a parting tool.
CNC Lathe Cutting Tools: What Are the Different Types of Lathe Machine Cutting Tools?
There are essentially three major classifications of lathe cutting tools – material, uses, and method of applying feed. The following provides the classifications, along with a breakdown of the common types of cutting tools we use in our CNC machining:
Lathe Cutting Tools Based on Material
Many materials are suitable for making cutting tools used on a lathe, each with unique characteristics:
- High-speed steel
- Carbide tool
- Diamond blade
- Cubic boron nitride
This type of steel, which can maintain hardness despite service temperatures up to 1000°, contains elements such as tungsten, carbon, vanadium, and chromium. High-speed steel cutting tools are known for their extreme hardness, strength, and wear-and-tear/heat resistance. They are ideal for rough machining and semi-finish machining.
These types of cutting tools are extremely hard and therefore ideal for iron, plastic, glass, stone, steel, and other difficult-to-cut materials.
This cutting tool is essentially a saw blade which has diamonds fixed on its edge. The tool is beneficial in the precision machining of brittle, wear-resistant, conforming, and hard materials like graphite, glass, or ceramics.
This cutting tool is durable, abrasion resistant, and suitable for rough machining and intermittent cutting, especially cast iron workpieces.
Lathe Cutting Tools Based on Use
Oftentimes we select a cutting tool based on what we are using the lathe to accomplish:
- Turning Tool
- Rough turning tools: These are used for removing large parts of a workpiece in a very short amount of time. They have a ground cutting angle that allows for the removal, and they can withstand maximum cutting pressure.
- Finish turning tools: These are ideal for removing small parts of the workpiece, and, like its name suggests, the end product has a smooth and accurate surface.
- Boring Tool
- Chamfering Tool
- Knurling Tool
- Parting Tool
- Thread Cutting Tool
- Facing Tool
There are two general types of turning tools in terms of their uses:
A type of lathe cutting tool used for enlarging a hole. The tool is inserted into a preexisting hole and used to widen the diameter.
These are lathe cutting tools used for creating a furrow on a part, or for creating smooth or jagged edges.
A type of lathe cutting tool that can produce knurled lathe parts by creating a specific pattern into a round section. The tool is often used to make grips for handles or grooves for fasteners.
A parting tool is a narrow-bladed tool used for removing pieces of material from a workpiece. It can function as both a turning tool and cutting tool.
As the name suggests, these tools are used to cut threads on a lathe part, whether they be internal or external threads.
This tool is used to cut a flat surface that is perpendicular to a workpiece rotational axis. The tool holder situated on the lathe carriage holds the tool during the process so that it can feed perpendicularly across the rotational axis of the part.

Lathe Cutting Tools Based on Method of Applying Feed
On occasion, we need to choose a cutting tool based on how we are going to feed the workpiece into the lathe:
- Right-hand tool
- Left-hand tool
- Round nose tool
A right-hand tool removes material when moving from right to left. The name is derived from the human hand – using your right hand, the thumb represents the tool feed direction. Therefore, the principal cutting edge is on the tool’s left side.
Unlike a right-hand tool, the left-hand cutting tool removes material when moving from left to right.
These tools can move from left to right or right to left, as they have no side rake or back rake angles. Due to the round edges, these tools are popular in machining parts with smooth surfaces.
