Single-Point vs. Multi-Point Tools: How They Differ

single-point tools

If you work in a mechanic shop or any other engineering-related business, you’re probably familiar with feed rates, short lead times, PCD tools, and the chipless machining method. You’re probably also familiar with a cutting tool. If not, a cutting tool removes excess material from an item allowing shape, accuracy, and size to be obtained.

There are two different types of cutting tools. The first type is a single point tool and the other is a multi-point cutting tool. While they ultimately do nearly the same job, there are actually many differences between them. Here’s what you should know about the differences and similarities between single point tools and multi-point tools.

Single-Point Tools

If you are using a single point tool to cut something, only one edge is going to engage with the material that you are trying to alter. Even if the single point tool has multiple cutting edges, only one of them will cut at any given time. If you cut something with one of the edges and then decide to use another in another sweep, you can do that to ensure accuracy and sharpness.

With single-point tools, since one cutting edge is always going to remain connected to the workplace, the temperature of the tool is going to be pretty high. If one of the cutting edges breaks while using it, you have to stop the entire tool before you can regain use. It won’t work properly until you replace the broken edge.

Multi-point Tool

Unlike a single point tool, a multi-point cutting tool will allow the use of more than one cutting edges at the same time. Multi-point cutting tools can have about four cutting edges or as many as several hundred. You don’t have to use all of them at the same time; in fact, how many edges you use depends on certain things such as the width of the material, depth of the cut, and infeed. Ultimately, the multi-point tool will allow multiple edges to be cut in one pass.

Since the amount of heat is spread throughout the entire tool, the temperature rise is going to be pretty low. Unlike the single point tool, if one of the cutting edges breaks, you don’t have to worry about stopping the process.

Single point and multi-point cutting tools are used for many different manufacturing industry (also known as a $2.17 trillion contribution to the U.S. economy) tasks. However, they’re both actually pretty different regardless of the fact that they do the same thing. Take a look at the differences and similarities listed above when choosing a tool for your specific job.
