![]() A downcut bit will push material down while it cuts, using an anticlockwise spiral. An upcut flute will have a clockwise spiral that pulls material away from the cutting surface. You can also split spiral flutes into two additional categories: upcut or downcut. It always stays in contact with the material and provides a much smoother finish. This is what a typical drill bit might look like. A spiral flute moves along the body of the bit and twists around. ![]() It will hit the material perpendicular to the direction of rotation, providing a less smooth finish, but it can be used at a higher speed. A straight flute, which is parallel to the body of the bit.Generally, there are two main flute types: The teeth will do the actual cutting while the flutes help to remove the waste material and get it out of the way, preventing any jamming. Teeth is the term used to refer to the cutting edges a bit has, while flutes are the grooves formed between each tooth. This is arguably the most important part of a CNC bit as it relates to the cutting power of the tool. The top part of a bit is usually just a solid material before it moves to the flute, it will then end with the tip - the part of the bit that touches the material you’re working on. Again, we will cover this in a later section. That’s exactly what a CNC router bit does, only it fits into the router/rig itself.ĭue to the versatility of a CNC router, you can come across many bits of different designs that serve specific purposes - more on that in the next few sections.īits are typically constructed out of specific materials designed to withstand the heat generated when performing CNC tasks. When you use a handheld drill, the bit fits into the end and is used to make holes in materials. The easiest way to think of this is like a drill bit. It will fit into your CNC router and be used to remove parts of a material based on your specific design. What Are The Applications Of CNC Router Bits?Įssentially, this is a piece of material that’s used to help you create your designs.What Are The Advantages Of CNC Router Bits?.So, we have created this basic (but complete) guide that tells you everything you need to know about CNC router bits: The question is, what are CNC router bits and what should you know about them? This can be a complex topic that throws up lots of additional questions, and it’s easy to get bogged down if you’re a beginner. In fact, they can be the difference between a final design that looks pretty good, and one that’s absolutely perfect. CNC router bits are critical to getting your rig working effectively. Plenty of elements and technologies make up a CNC router, but one of the most important aspects is the bit. ![]() When used correctly, you can see stunning results that are impossible to recreate by hand or through other manual machinery. Typically, this machine is used for milling, drilling, or cutting multiple materials. You can use a CNC router for various different projects. The Basic(But Complete) Guide of CNC Router Bits ![]()
