The Comprehensive Guide to CNC Turning Tools

Choosing the right Computer Numerical Control (CNC) turning tools for your machine is not an easy task. Several factors, from the metal alloy to the desired final product, must be taken into consideration. This post aims to make your choice a bit easier, presenting a vast catalogue of CNC turning tools and guiding you on how to make the best selection.

Introduction to CNC Turning Tools

Firstly, let's introduce the topic for those who are new to CNC turning. CNC turning tools belong to a broad category of cutting tools used in manufacturing, specifically for removing material from the workpiece. They are designed to rotate on a CNC lathe machine, enabling the shaping, sanding, knurling, drilling, or deformation of a wide array of materials.

Different Types of CNC Turning Tools

1. Insert Turning Tools

Insert turning tools, also known as replaceable tip turning tools, are highly popular due to their versatility and cost-effectiveness. As the name implies, these tools have replaceable cutting tips, allowing you to change them as needed, without having to purchase an entirely new tool. They have the capability of cutting in any direction, be it longitudinal, facing or profiling.

2. Boring Bars

When you need to create or finish holes in a workpiece, boring bars are your go-to CNC turning tools. They not only bore holes but can also enlarge them or fine-tune them for an excellent surface finish.

3. Threading Tools

Threading tools are essential when you want to create internal or external threads on a workpiece. They come in various designs, depending on the thread form and pitch you need.

4. Parting and Grooving Tools

These tools have been designed to cut grooves into the workpiece or part sections of it. They have precision-ground cutting edges that offer an excellent surface finish.

Choosing the Right CNC Turning Tools

Now that we've covered the main types of CNC turning tools, it's time to delve into the nitty-gritty of how to choose the right one for your job.


The type of material you're working with is the first factor you should consider when choosing your CNC tool. Different materials have unique properties and require differing tool angles, speeds, and feeds.

Workpiece Geometry

The second factor to consider is the shape and size of your workpiece. Some tools, like boring bars, are perfect for creating precision holes, while others are better suited for grooving or external turning.

Tool Material

The tool material, also known as the grade, is another crucial factor. The grade determines the tool's ability to withstand heat and wear, directly impacting the tool's lifespan and performance.

Type of Cut

The type of cut you need to make also influences your choice. For intricate detailed cuts, carbide tools with high cutting speeds and minimal tool pressure are best. For roughing cuts that remove substantial material, you should choose a more durable tool, such as a diamond-tipped tool.


Selecting the appropriate CNC turning tools comes down to understanding the material you're working with and the type of cut you need to make. Remember, investing in quality tools that suit your specific requirements will not only improve your workpiece's final look but also save you time and money. With this comprehensive tool catalog, you're well on your way to making an informed choice on your next CNC turning tool purchase. Keep referring back to it as your manufacturing needs and goals evolve.
