Categorization of various router bits and making selections from a seemingly endless variety can be a little bewildering and bothering, particularly if you are new to woodworking with a router or a router table. Studying about the basic facts will help you to choose the best router bits and to make the most sensible use of them.

Straight Bits:
Straight Routing bits are used to make cuts straight down into a material to form a groove or dado or to hollow out an area for a mortise or inlay. They come in a selection of cut diameters, most widely in the range all the way from 3 / 16″ to 1- half “.

Rabbet Router Bits:
Rabbeting Router Bits produce straight, horizontal and/or vertical cuts. These are designed especially to cut a rabbet (notch) on the edge of material. Rabbeting is a real example of a piloted bit. It means that a bearing of the top of the bit is used to guide that along the fringe of the material. Rabbet bits often come in a set that includes a range of pilot bearing diameters, allowing a single one to supply a variety of rabbet dimensions.
These are used to trim the edges of the material flush with the edges of another material. Trimming a finished surface flush with a substrate, or employing a pattern to form multiple identical shapes are few examples. The pilot bearing could be on the top of the bit, at the base of the leading edge, or both.

Chamfer Router Bits:
Chamfer Router Bits produce a bevel cut at a particular stated angle. Chamfers are just occasionally used to embellish the fringe of material. These can also be utilized to form beveled edges for multi-sided constructions.
Edge Forming Router Bits:
Edge forming router bits are most frequently and simply used to chop an ornamental edge into a material.
The diversity of edge forming profiles are unlimited, but some of the most common include:

Round over bits:
These bits are used to chop a rounded edge of a fixed radius.
Ogee bits:
The term ogee refers to an “S” formed profile. Ogees can be gotten in a bunch of configurations. The Roman ogee bit is one of the commonest.
Edge beading bits:
These bits are used to chop a quarter or half circle profile called a bead into an edge or corner
Cove router bits:
Cove Bits are used to chop a concave circle into a material. Many edges forming bits include a pilot bearing also.

Molding Router Bits:
These are engineered to architecture the molding profiles and are sometimes bigger than the basic edge bit. Molding bits may sometimes incorporate multiple basic edge-forming profiles into a single bit. Because of their size, molding such bits most safely be utilized in a router table.

The Classic Multi-Form Bit:
These are meant to make several ornamental profiles by combining other basic profiles included in a single one. These bits cut an ornamental profile and a panel slot into the fringe of a door frame wood stock and also make a correspondent cut into the end of the material where the frame’s rail (horizontal member) meets the profiled edge of the frame’s stile (vertical member).
These bits are available either as a collection of two matched bits or as a single that can be organized to chop each of the required elements of the cope and stick joint.

Raised Panel Bits:
These are often used in combination with the prior type to supply a profiled edge on a door panel. The profiled edge fits into the corresponding slot in the frame’s stiles and rails. Raised panel bits are available in both horizontal and vertical configurations.
Horizontal raised bits cut the panel profile with the panel stock laying flat on the router table. A horizontal raised panel bit is also required for panels with curved edges. For example, Those used in arched top or cathedral cabinet doors.
A vertical frame and panel bit is used to cut the panel profile with the stock tipped up on its edge and run along the fence of a router table. Vertical raised are thought to be safer in operation due to their way smaller radius.

Joinery Bits:
These include dovetail, finger joint, drawer locks and lock miter bits. Each of these is used to produce a specialized kind of precision joint. A dovetail is often used together with a dovetail jig to promptly and accurately produce dovetail joints for drawer boxes and other boxes – making projects.
