4PCS Straight/Dado Router Bit - 3/8"W x20"H -8" Shank Cutter for Wood
Straight router its are the most widely used and versatile bits in woodworking. They are ideal for joinery such as box joints, lap joints, dados, rabbets, mortises and tenons. You can also use straight bits for trimming operations and CNC work. Straight bits 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. Straight bits come in a variety of cut diameters, most commonly in the range from 3/16" to 1-1/2".

Router Bit Quality:
A number of qualities distinguish better quality router bits from "bargain" bits. Good quality router bits are sharp, and stay sharp for a long time (with proper use). Good bits are well balanced and therefore create minimal vibration. They are designed for good cutting geometry and have excellent chip ejection properties. Currently, most woodworkers prefer carbide tipped router bits. Carbide cutters can hold their edge between ten and twenty-five times as long as hss (high speed steel) bits. Better carbide bits are ground to a finer edge and have thick cutters to allow for numerous regrindings. They are also made of high quality, fine grained carbide, which allows for a sharper cutting edge.
How to Choose a Router Bit for Dado Cuts?
You cut dadoes and grooves with straight bits. That's pretty simple. While you can use specialized dado-cutting bits, the commonplace, conventional straight bit - the double-flute - will give excellent results for all but the most troublesome workpieces.
A variant of the double-flute straight that is valuable for dadoing plywood is the shear-cut straight.
This bit's cutting edges are at a slight angle (usually about 3 degrees) to the bit's axis. A down-shear bit slices down on a face veneer, yielding a cleaner edged cut.
Straight bits are made in an enormous variety of sizes. Cutting diameters range from 1/16" to 2", with flute lengths from 1/4" to 2-1/2". Even metric sizes are available.
So how do you choose? The rule of thumb has long been: Use the shortest length that'll do the job. Dadoes seldom exceed a 1/2" depth, so a bit with the 3/4"-long flutes - a size common in bit sets - is plenty long. Shorter is better if you do a lot of dadoing. For stopped dadoes, make sure you are getting bits that have plunge-cutting ends. Most do these days, but check before you buy.
