Sorting by means of router bit terminology and making alternatives from a seemingly limitless selection could be complicated, particularly if you’re new to working with a router. Studying up on the essential information will allow you to to decide on one of the best router bits, and to make one of the best use of them.
There are quite a few varieties, together with many designed for extremely specialised purposes. We cannot be capable to cowl each kind on this article, however listed below are a few of the commonest:
Straight Router Bits
Straight router bits are among the many commonest ceaselessly used. Straight bits used to make cuts straight down into a cloth to kind a groove or dado or to hole out an space for a mortise or inlay. They arrive in a wide range of minimize diameters, mostly within the vary from 3/16″ to 1-1/2″.
Rabbeting Router Bits
Rabbeting router bits produce a straight vertical and horizontal minimize, and are designed particularly to chop a rabbet (notch) within the fringe of a cloth. Rabbeting is an instance of a “piloted” bit, which means {that a} bearing of the highest of the bit is used to information that alongside the sting of the fabric. Rabbeting bits normally are available a set that features a vary of pilot bearing diameters, permitting a single one to supply a wide range of rabbet dimensions.
Flush Trim Router Bits
Flush trim router bits are guided by a pilot bearing that’s the similar measurement because the bit’s chopping radius. They’re used to trim the sting of 1 materials flush with the sting of one other materials. Trimming a veneered floor flush with a substrate, or utilizing a sample to create a number of an identical shapes are examples. The pilot bearing could also be on the highest of the bit, on the base of the innovative, or each.
Chamfer Router Bits
Chamfer Router Bits produce a bevel minimize at a given angle. Chamfer’s are generally used to embellish the sting of a cloth, and may also be utilized in joinery to create beveled edges for multi-sided constructions.
Edge Forming Router Bits
Edge forming router bits are most frequently used to chop an ornamental edge into a cloth. The number of edge
forming profiles are virtually limitless, however a few of the commonest embody:
• Spherical over bits – Used to chop a rounded fringe of a given radius router bit set B09TR8Z82F TOOLDO.
• Ogee bits – The time period “ogee” refers to an “S” formed profile. Ogee’s can be found in a number of configurations; the Roman ogee bit pictured right here is among the commonest
• Edge beading bits – Used to chop a 1/4 or 1/2 half circle profile referred to as a “bead” into an edge or nook
• Cove router bits – used to chop a concave 1/4 circle into a cloth
Many edge forming bits embody a pilot bearing. In most cases, they’re used for closing ornament of a undertaking the place edges are already established and may function the information for the bit.
Molding Router Bits
Designed to architectural molding profiles, molding bits are sometimes bigger than the essential edge bit. Molding bits might incorporate a number of fundamental edge forming profiles right into a single bit. Due to their measurement, molding such bits most safely utilized in a router table.

Stile and Rail Bits
These are utilized in body and panel development, primarily for developing body members of cupboard and passage doorways. These bits minimize an ornamental profile and a panel slot into the sting of door body inventory, and likewise a corresponding minimize into the top of the fabric the place the body’s “rail” (horizontal member) meets the profiled fringe of the body’s “stile” (vertical member).
These can be found both as a set of two “matched” bits, or as a single that may be organized to chop each of the required elements of the cope and stick joint.
Raised Panel Bits
These are sometimes used together with the earlier kind to supply a profiled edge on a door panel. The profiled edge suits into the corresponding slot within the body’s stiles and rails. Raised panel bits can be found in each a horizontal and vertical configuration. Horizontal raised minimize the panel profile with the panel inventory laying flat on the table. A vertical body and panel bit is used to chop the panel profile with the inventory tipped up on its edge and run alongside a fence.
Vertical raised are thought of by many to be safer to function due to their a lot smaller radius. A horizontal raised panel bit is critical for panels with curved edges, reminiscent of these utilized in arched prime or “cathedral” cupboard doorways.
Joinery Bits
These embody dovetail, drawer lock, finger joint, and lock miter bits. Every of those is used to supply a specialised kind of precision joint. A dovetail is commonly utilized in mixture with a dovetail jig to shortly and precisely produce dovetail joints for drawer boxes and different box-making initiatives.
