For intricate, precise finishes, bur end mills are an invaluable tool in machining. Outclassing conventional end mills, these specialized tools ensure that your workpieces have neatly machined burr-free internal corners – creating a smoother finish than other alternatives.

Every project is unique, thus, requiring the right type of bur end mill to be utilized to achieve optimal results. When selecting a bur end mill, there are three common shank sizes available – 1/4″, 3/8″, and 1/2″. Furthermore, the style of the bur end mill can play a determinant role in its efficiency and expediency.

For milling projects, two different sorts of end mills can be employed: ball end mills, with their mellow round tip for a smooth finish; or spiral end mills’ fluted tip to provide a rough, textured result.

When selecting the right bur end mill, the material to be worked with is paramount to think about. Harder material requires the intervention of a spiral end mill, whereas softer materials can be manipulated effectively utilizing a ball end mill. It is also important to consider that the type of material affects the speed and depth of cut.

End mills offer incredible versatility to cutters due to their ability to be employed for various operations. When handled appropriately, they can provide a perfect, refined finish to any job.
