New to Looking at End Mills for Sale? What to Know Before You Buy
When it comes to end mills, there are a lot of different options available on the market. These versatile tools are what give milling machines their cutting power and finding the right end mills for sale is essential if you want to get the job done right. If you are new to the world of milling machines, then it is important to know a few things about these tools before you invest.
All end mills have a few things in common. They have a shaft that is held by the machine’s chuck and a cutting surface that can come in a wide variety of shapes and sizes. The first thing to consider when shopping for end mills is to consider the types of projects that you plan on working on. Obviously standard square end and ball nosed mills are essential for quickly removing material, but most jobs will also require some more specialized cutting tools like a chamfer cutter or thread mills. The size of your tools will have an impact on removal rates and the corner radius of their cuts, which is why it’s always a good idea to own tools in multiple sizes.
In addition to considering what you need tools for, it is also important to consider the material that you are going to be working with. Different materials have different properties when machined. If you try to cut into soft aluminum with a high flute count end mill designed for steel or cast iron, then you run a serious risk of the large aluminum chips clogging up the teeth of the cutter. This can damage both your cutting tool and your workpiece.
The material that you are cutting is not the only thing you need to think about, there is also the material you are cutting with. A lot of tools are made from different tool steel alloys. These alloys are strong, but they have to be heat tempered to maintain their rigidity. If the tools get too hot from operating at high temperatures, the tools can lose their temper and soften. High speed steel or HSS tools can handle pretty high temperatures, but they can still lose their temper and wear down quickly. If you want end mills that will last and handle higher temperatures, then carbide tools are definitely the best option. These tools get their cutting power from ceramic granules in the tools surface, so they are virtually immune to heat and last significantly longer than steel tools.
