A router is one of the most important carpentry power tools which offer great versatility and convenience. The woodworker’s tool kit is incomplete without a Router and set of router bits. Woodworking router bits are used to perform tasks like cutting, paneling, siding, sheathing, grooving, joinery, edge profiling, and special molding on wood with the highest speed and accuracy. However, it is equally important to use the right router bit to get the desired cut with the highest efficiency and accuracy, and with minimal effort. The wide varieties of router bits available in the market are no less than a treat for woodworkers. However, having a lot of options available means a lot of confusion. I have come up with router bit profiles to clear your confusion and meet your demanding cutting needs.
So whether you are a professional woodworker or a DIYer, this article will help you in making the right choice. In addition, the purchase link is also attached to each product and it is reviewed by our team of professional woodworkers.
Woodworking router bit profiles are discussed below.
Grooving bits consist of a shank and cutting edge with no pilot. These bits are used to groove the shaft on plane surfaces of any material. Grooving router bits profiles are;
Veining router bits
It is nothing but a narrow version of a round nose or V-groove router bit which is an inch wider. Veining bits are ideal for sign-making, freehand lettering, or numbering on the surface of the material. The veining bit is used for recessed decorative veins into the cabinet and door front grooving.
Straight router bits
Straight bits are the most commonly used woodworking router bit. It is designed for routing grooves, cutting dados, rabbet joints, mortising, hinge recessing, and carving in the middle of the wood. It cuts on the sides of the material as well as at the bottom which is a square-shaped groove. While using straight bits you first need to plunge the bit into the wood depending upon how deep you need to cut and then move the bit in any direction.
It can also be used for mortising door hardware or to groove a channel to insert a decorative piece in it. Most commonly used straight bits have one or two flutes. It is recommended to use a single fluted bit where the cut speed is more important than the cut finish. However, more advanced cutters have 3 flutes which give smooth, clean, deep cuts for mortising with quick clearance of waste. In addition, it is available in different shank diameters ranging from 3/16 inch to 1 ½ inch.
V- groove router bits
As the name suggests v- groove bits are used to get the intricate cut with beveled sides and shallow or sharp ridge at the bottom. In other words, the v groove router bit is used to get a double chamfer profile in the middle of the stock. Bits come in different diameters which have different widths and depths of the cut. V groove bits are 90 degrees that are each cutting edge measures about 45 degrees from the bit axis. However, for lettering and freehand designing 60-degree profile is preferred therefore it is also available with 60-degree beveled edges. V groove bits are a great choice to create fluted columns and beadboard appearance on the panels, chamfer edges, sign making, and engraving designs on furniture to create a decorative effect. In addition, flat-bottom v-groove router bits are also available. It is mainly used to route outdoor signs and limit the depth of the cut.
Core box or round nose
A round nose router bit is used to rout a Scotia or a concave shape less than 180 degrees. It is more or less similar to cove bit, except that it is used for routing grooves and flutes in the middle of stock. Bits are available in cutting diameters ranging from 1/8 to 1.2 inches. However, it is recommended to use a 1/2-inch round nose bit for a deeper and wider cut. Round nose router bits are excellent at making rounded-bottom slots or grooves for sign-making and fluted millwork. It is also used for fluting and stock removal in raised letters signs and bowls and as a handrail bit for stairs. It is also known as core box bits used for making shallow, round-bottom grooves of variable depths.
Hinge Mortising Bits
A mortise is a slot carved into the wood which interlocks with tenons on the adjoining piece to get a strong joint. Mortising bits are used to carve square-shaped slots for hinges, locksets, and cutting mortises.

Flush Trim Router Bits
Flush trim router bits are straight bits with a pilot bearing at either end of the flute which allows the cutter to trim off the surface the bearing is riding on. The flute with a down shear angle gives a smoother cut as compared to the straight bits. A flush trim bit is used to follow a pattern or to get rid of excess material. Flush trim router bit with the upper bearing guides the cutting arm around the edge of the material. However, the use of the top bearing or bottom bearing bit depends on the preference and type of operations the user is going to perform. One disadvantage with the use of top bearing flush is while following a pattern if you accidentally move the cutter slightly you may end up cutting the workpieces. In contrast, if you make the same mistake with the bottom bearing the bit moves away from the workpieces. So, all you have to do is make another pass to fix the mistake. A flush trim bit is ideal for making curves, shelf edging, veneer trimming, making custom patterns, and duplicating things like the legs of the table or the parts of chairs, etc.
The rabbeting bit is used to get a step cut or an L- shape cut on the edge of the wood to form a rabbet joint. Rabbets can also be cut using straight bits or a table saw but rabbeting bits offer superior results and improved efficiency. Rabbet joint is utilized in cabinet making to join adjoining sides or to connect sides to cabinet tops, to install cabinet backs and to build drawers, etc. A rabbeting bit has a ball bearing pilot at the tip which guides the bit riding along the edge of the material to make a perfect deep cut.
