One other very handy cut the straight cut bit can make is a plunge cut. This is when the bit is lowered down on to the surface and then starts to cut down in to it. Again as with other router bits that need to cut accurately, these bits also feature a pilot bearing guide fixed to the base of the bit. As you may have guessed from the shape of the bit in the image below, the core cutting bit cuts channels and shapes with a concave bottom.

As with chamfer bits, it’s generally used on the edges of shelves, tabletop and cabinet edges the arms of chairs and any other area that requires a smooth edge. Rabbet cutting router bit and rabbet or shoulder joint cut – Image courtesy of mullerconstructionsupply.com Edge Cutting Router Bits Again it’s generally used for forming decorative grooves in many different objects such as table tops, table and chair legs and various aspects of cabinet making and the similar. Due to the nature of a bearing and it’s very smooth rotation, this helps to avoid the router bit juddering or jumping around, keeping any cuts dead straight and accurate to the surface you are working on. This project should be read in conjunction with our project on how to use a router found here. What are the Different Parts of a Router Bit?However their main purpose is for creating decorative edges commonly used on tables, doors of various types, shelves and the similar. The rabbet cutting router bit is specifically designed for cutting rabbets, not the small cute furry ones found in most gardens but the rabbet joint or shoulder joint as it’s also known ( find out all bout rabbet or shoulder joints in our project here). Rabbet or shoulder joints are a common type of joint used when making furniture, specifically for building drawers and joining together cabinet framework. Unlike performing any of these tasks using other tools such as planes or saws, a router with the correct bit will give a 100% accurate and clean cut when used correctly. The purpose of the bearing is to allow you to easily guide your router bit along a piece of work so that your (normally) shaping or detailing work is kept straight and accurate.

As the bit is also non-guided e.g. it does not feature a bearing it can also be used to great effect for hollowing out objects. Due to this if the profiles are cut the same then essentially a rounded off joint will fit into a cove-cut joint. The name edging bit or edge cutting bit is a bit of an umbrella term as there are several different types depending on eth shape of edge you want to create. Typically edging bits are available to cut the following shapes: Chamfer or bevel cutting bits are also available in a range of different cutting angles including 11.25°, 15°, 22.5° and 30° allowing you to create a range of different shaped objects. The edge cutting bit is again commonly used in cabinet and furniture making for cutting and creating decorative edges, sometimes known as beads in cabinet and table tops, chair and table legs and many other different objects and surfaces.Carbide bits are tougher than standard HSS bits so on the whole will last much longer and keep their sharpness for considerably longer, however they are brittle and can easily damage if dropped you need to take care of them!
