Milling cutters can be an important part of machine shop operating expenses and there is much to know about cutters. For example, there are many different types of HSS and carbide end mills on the market today and it is important to choose the right tool for the job. Let’s check out some of the many options you have, to help you make the best decision.
What are Flutes?
Flutes are the cutting edges on milling cutters. The number of flutes you have can make a big difference. For example, most HSS and carbide end mills are either two or four flutes.
A two flute cutter gives you the most room for ejecting chips from your work and keeping it clean. Three flute cutters are used for general or everyday milling. Some people opt for four or more flute cutters. This will give you a finer finish on the product and you can choose up to eight flutes.
Flat or Ball Nose?
Milling cutters can have flat or ball shaped ends. Normally flat ends are used to make rough cuts and ball nose cutters can be used for finishing and more detailed work. Ball nose cutters are round or spherical shaped on the ends.
Carbide or HSS?
You can choose either high speed steel or carbide end mills. Carbide is a good choice for hard metals and very high speed milling operations. In fact, with quality carbide cutters you can mill much faster than HSS or cobalt and enjoy longer tool life. However, you will also pay more for this benefit.
Many More Choices
When it comes to milling cutters, you may choose from corner rounders, double end, drill point, single end, high helix and more. When you choose one of the best tool suppliers, you have assistance with selecting the perfect tool for the job.
