The art of threading requires a supportive tool holder to keep the cutting tool firmly in place. Luckily, there are a variety of choices available for the task, each one tailored to a particular form of equipment. When threading with round tools, the go-to is the collet. But when square or rectangular shapes are called for, there’s the chuck; for those special-shaped tools, you’ll need the jig; and if a long, thin item needs cutting, that’s where a mandrel finds its application. Whatever you need, there’s sure to be a threading tool holder right for the job!
The composition of a threading tool holder can vary, depending on the type of tool it is intended to hold and its intended application. Depending on the situation, steel, aluminum, or plastic may be used. For instance, if an individual intends to use the holder for tasks involving rigorous machining processes, a stronger material will be chosen for construction than what would be selected for light-duty projects.
The tool holder for threading tools must be selected with careful consideration given to their size; neither too large, nor too small. If it is not the correct size then it will either make it difficult to manoeuvre the tool or it may end up impeding progress. The best size for the tool holder is dependent on both the size of the tool and the material from which it is constructed.
Attaching tool holders to tools can be done in a number of ways, the most popular being the use of a setscrew. Additionally, this can be achieved through utilizing a collet chuck or drill chuck, depending upon the type of tool and its purpose of use.
After proceeding with the connection of the tool holder to the tool, its time to get ready for use. Placed into the holder, this tool requires attachment to a lathe before functioning. Activated, the lathe will begin spinning and feeding the tool into its workpiece. As the tool begins to cut through, a thread is created within the shape. Its depth is dependent on two factors – the speed of the lathe and the tools feed rate.
After providing the perfect cut, the tool is taken out of the workpiece and the lathe powered off. Then, the threading tool holder is removed from the instrument, and returned to its slot. When desired results are achieved, this procedure can be repeated as much as needed.
