Metal lathes are indispensable tools in machining, shaping raw materials into precision components. In a first look, lathes are odd tools. The entire machine is oriented side by side, and the workpiece is in a horizontal position. Also, a crucial thing to note here is that the tool itself doesn’t spin.
Instead, the workpiece rotates, and the tools will slide side to side along the bed’s length. Simply put metal lathes neither look nor do they function as the regular drill. Therefore, it can be challenging for a beginner to use them. Nevertheless, this article will help you with using a metal lathe.
We’ll tell you about how to operate a metal lathe safely. This article will give you a comprehensive idea about the core components of this tool and how you can use it safely. You will ensure that you can safely use the VEVOR metal lathe. Let’s start by understanding the basics of metal lathes.

Understanding the Basics of Metal Lathes
A lathe is a useful tool that can help you work with wood or metal. The metal lathe turning process is quite different from the standard drill or mill. The cutting bit will not spin, rather it will move into the rotating workpiece. Compared to a drill or a mill, the workpiece is still, and the cutting bit rotates.
But that is not the case with the metal lathe. Furthermore, there are three basic types of metal lathes:
- Turret Lathe – It is common in industrialized manufacturing processes. This lathe incorporates a multiple-headed turret so that it can hold more than one cutting bit.
- Special Purpose Lathe – This type of lathe is usually on the assembly lines where they will create customized parts as a core element of a specific process.
- Engine Lathe – The engine lathe has everything including a moveable head, tailstock, headstock, etc. The workpiece will be in between the headstock and the tailstock, where the former will move and engage in the cutting part.
So, there you have a brief idea about what is the lathe machine. But there are other things that you need to keep in mind as a beginner. Let’s move on to the critical components of a robust metal lathe for your projects.
Metal Lathe Cutting Tools: A Closer Look

Since a metal lathe is a versatile machine, you can equip it with a wide range of instruments according to your project needs. Here are a few types of metal lathe-cutting tools.
Boring Bars
The boring bars help in widening the existing holes for pieces that are on the lathe. This tool will pierce into the wood or metal, which will give you plunge cuts that you can thread or smooth out.
External Turning
External turning tools play a major role in removing the most amount of material quickly. You can also find rougher versions of these tools to shape the piece according to your convenience. Once this process is complete, the finishing tool will bring out the polished surface.
Threading
One of the biggest categories of the various kinds of lathe tools is threading. You can find a wide range of thread cuts, such as:
- Square
- Small
- Large
As a metal lathe beginner, you can use the threading tools for internal threads, such as a nut, or external threads like the ones on the screws or bolts.
