![]() ![]() It is used to slot or plunge softer materials like wood and some metals like aluminum. ![]() HSS (High-Speed Steel) – Compared to coated carbide, it is economic and is good wear-resistant. ![]() They are highly heat resistant which makes them feasible to use for tougher materials. MATERIALįollowing are the two main materials used to manufacture cutting tools, carbide, and HSS.Ĭarbide – These are more expensive compared to HSS because they offer better rigidity and operate up to 3 times faster compared to HSS. These features in an end mill define the functioning of the end mill during the machining operation and cutting possibilities with regards to shape and performance. There are numerous types of end mills based on shapes but categorically, they are divided into 7 types: The geometry of end mills is divided into the following specifications: If you need metric End Mill PDF Catalog please view: If you need inch size PDF Catalog please view : Metric size end mills: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5 etc. use metric size end mills.įollowing are common inch size and metric size end mills: use inch-size end mills whereas Asia and Europe, etc. There is no technical difference between an inch size end mill and a metric size end mill, it is just the unit conversion with micro variation in measurement that occurs during conversion from one to another unit.Ĭountries like the USA, Canada, Mexico, etc. Though end mills also plunge into the material, their unique profile-creating capability makes them far more versatile than drill bits.ĭIFFERENCE BETWEEN INCH SIZE AN METRIC SIZE END MILLSīecause different countries use different units of measurement, the end mills are available in units of inches and millimeters. Many people consider they are the same, but actually, there is a prominent dissimilarity between the two.ĭrill bits plunge into the material directly thus merely creating holes, while the end mills cut the workpiece laterally thereby creating profiles or slots. DIFFERENCE BETWEEN END MILLS AND DRILL BITSīefore we dive into the details of the end mill’s components, you should know the answer to a common question about the difference between end mills and drill bits. After reading it completely, you will be able to do a well-informed selection over a variety of end mills. In this blog, you will know about all the details of specific components that make up an end mill. The end mills are composed of many components each serving a vital purpose in performing a specific operation over a workpiece. It is a crucial component for industrial milling applications. End mills in a CNC machine play a vital role in creating slots or 3D contouring over a workpiece during profiling, drilling, reaming, etc. ![]()
