7/1/2023 0 Comments End mill bits for drill![]() ![]() The benefit to this style of bit is that, by pressing down against the material, it can help thin materials remain secured to your cutting surface. This cutting style is prone to melting or burning your material, especially if your job requires many passes. However, because of the bit's design and upward-pulling motion, it can fight the clamping system you use with your material, especially if your material is thin.ĭown-cut bits push the chips downward (towards the material). It pulls heat away from the bit, and is a good choice for plastics, metals, or other materials that are prone to melting or burning. Up-cut bits expel the cut material upward and smooths the bottom of the cut pass. The cutting style of a milling bit identifies which way the material chips are removed from your project, in addition to which side of the cut surface is smoothed. It is most important to make sure your bit fits in your spindle/router (shank diameter) and then use choose the bit with the right cutting diameter for your project. Shank diameters and cutting diameters are not always the same. If your job has detailed elements that cannot be cut by your selected bit, Easel will recommend you select a smaller bit. When selecting the right bit for your project, aim to select a bit with the largest possible cutting diameter for your job. Cutting diameters can range anywhere from a few inches (for leveling surfaces) to 1/64" or 1/32" (for very fine details). The cutting dimeter is the overall cut diameter of your bit. Our 1/8" collet for the DeWalt 611 is a common upgrade many of our customers make as they start doing more complicated, detailed work. If you want to use bits that have a smaller shank diameter, you'll need to buy a collet and nut adapter for your router. For instance, the DeWalt 611 router holds bits that are 1/4" in shank diameter. Many routers are designed to hold a specific diameter bit. This end of the bit is inserted into your router. The shank diameter is the diameter of the non-cutting part of your bit. ![]() You can learn more about what bits to use with your material here. ![]() Different materials have different qualities that impact your carving and your bit's behavior. Please keep in mind that the type of material you're using with your machine is the most important factor in determining what bit you should use. Understanding what different bits do and how they work can help you choose the right bit for your project. If you're new to CNC machines and carving, the information below outlines the various qualities of bits. (Drill bits cut into or through a piece of material.) End mills come in a variety of styles and are designed to help you get the desired effect for your specific project. They are designed to cut horizontally (laterally) across a surface. End mills, also called milling bits, are the most commonly-used bits used with CNC machines. ![]()
