![]() ![]() They are also used to cut out pattern templates and are usually guided by a pilot bearing the same diameter as the cutter. These are used to trim the edge of one material flush with the edge of another (e.g., trimming a veneered surface flush with a substrate or using a pattern to create multiple identical pieces). Rabbeting bits are used to create rabbets and lap joints and are great if you need identical rabbets for projects like creating a picture frame from scratch. They are designed with straight or spiral flutes and can be used for both functional and decorative cuts. Straight bits have a side and bottom cutting edge and come in a variety of diameters and lengths. ![]() Their name comes from the fact that they make cuts straight into the material to form a groove or dado (groove across the wood grain) or to hollow out an area for a mortise or inlay. Straight bits are the most common type of bit and are thus typically the most useful for both novices and seasoned pros alike. Here’s a look at some of the most common types of router bits with some background for each. Router bits come in a wide variety of types, each with its own unique characteristics and preferred applications. Two of the most popular sizes of router bits are 1/2-inch and 1/4-inch.ġ/2-inch router bits provide better stability and overall performance than smaller router bits, and in most cases serve as a good starting point unless doing specialized or small-scale work.ġ/4-inch router bits are often more preferable for fine- or slight-edge work – although in many cases, the same work can be done with a 1/2-inch router bit. There are many options for tooling sizes which should be determined by the goals of the project and your equipment’s ratings. Milling bits – also known as carving or engraving bits – are designed to move across the surface of the workpiece, clearing away chips as they move in order to create 3D designs. They are best used for jobs requiring material to be removed straight down (e.g., pre-drilling holes for screws or pegs). Generally speaking, router bits can be broken up into two primary groups as far as their purpose goes: drill bits and milling bits.ĭrill bits drive straight into the material and don’t have any side edges, meaning they can’t move laterally while boring into the material. Here is a closer look at the varying options of router bits based on purpose, size, type, and material to help you make the right selection for your next project. ![]() Investing in bit sets also helps keep your router bits organized so you can always find the one you need at a moment’s notice. For that reason, it’s smart to invest in a router bit set or two to ensure you have a versatile variety at your disposal. The term “router bit” refers to the object that creates the cuts, joints, grooves, and profiles within your workpiece – and there are many different options to choose from. A CNC router can provide your shop or project with much-needed precision and efficiency – but to make the most of these benefits, you have to make sure you’re using the right router bit to get the job done. ![]()
