Completing a custom component on a milling machine means having to use several different tools to perform different tasks. While standard square and ball ended milling cutters are the standard option, but it takes specialized tools in order to complete specific tasks. A simple but important tool for finishing custom milled components is the chamfer end mill. These little tools are a great way to give your workpiece a finished look and feel.
A chamfer end mill is typically a short and pointed cutting tool. Instead of being designed to remove large amounts of material or drill holes, these tools have been specifically designed to chamfer the edges of a workpiece, giving them a clean look and feel. For anyone unfamiliar with chamfering, it is the process of removing material from the edge where two faces of a workpiece meet. This can help break sharp edges by providing an intermediary surface. Chamfering an edge is typically one of the final stages in the milling process, as it is used to finish edges that have already been cut.
In addition to chamfering edges, a chamfer end mill can also be used to bevel an edge. While these two processes are often confused for one another, they are actually quite distinct. Unlike chamfering, which removes material to create an intermediate edge, the process of beveling removes material to completely change the angle at which two faces of a surface meet. This can involve the removal of more material, but can typically be accomplished with a few passes using a chamfering tool. Small bevels can be accomplished using a single pass depending on the size of your cutting surface.
Chamfer tools can also be used to complete other finishing tasks that involve the use of a fine point. While the cutting point of a chamfer tool should not be used to drill down into a piece like a spotting drill, it is strong enough for a range of tasks. The point of your chamfer cutter can be used to trace along your workpiece’s edges in order to deburr them. This process helps to remove the sharp metal burrs that are occasionally created by the incomplete removal of material. The point can also be used to engrave details in a workpiece, making chamfer tools a great choice for adding small details to your piece.
One of the things that make chamfer tools such a great option for performing finishing tasks is the short length and small cutting surface. This makes these tools extremely stable. One of the best ways to ensure the most stable performance is to choose tools manufactured from solid carbide. Carbide is a combination of powdered ceramic and a cobalt metal binding material. The ceramic carbide content not only helps to retain hard cutting edges, but also increases the tools rigidity over steel tools.
