The first choice for the average rabbeting operation is the rabbeting bit, which has a pilot. It minimizes setup: The only adjustments you can make are the depth of cut and the angle of attack. The measurement between the bit s cutting edge and its pilot governs what 1 call the width of the rabbet. (A lot of bit manufacturers call this the depth of the rabbet.) You insert the bit, adjust the depth setting, and rout. It is simple, but because it is, it doesn't allow much variation.
Freud offers two rabbeting bits in its basic catalog. The difference between them is the shank size: One is Y* inch, the other is Vi inch. Both cut a y«-inch-wide rabbet up to Yt inch deep. With either bit, one of the rabbet's dimensions is going to be Ys inci; the other can vary only up to Yi inch. Dosch and Amana take this a step further by adding bits that cut l/2-inch-widc rabbets to the basic Vs-inchcr. If you scrutinize the listings of Byrom and Cascade, which seem to be longer, you'll find the variation is in the length of the carbide flute, not in the space between cutting edge and pilot.
To alter the width of the rabbet with such bits, you can do two things. One is that you can change your angle of attack, as shown in Angle of Attack. This can be a useful approach, since it can change the dimension over which you have control, while preserving the simplicity of setup and operation that pilot bits provide.
The other thing you can do is to change the pilot bearing. Several bit manufacturers sell bearing "kits" that will give you four different widths of cut from one bit. (See "Bit Drawer" on page 249.)
(There is a third thing you can do. and that is to circumvent the pilot somehow—using ar. edge guide or a fence. You can only narrow the cut using this approach, hut it's valid, it works. If you take this approach, though, you probably should question why you are using a rabbeting bit and not a straight bit.)
The piloted bit can be used in both hand-held and table-mounted routers, of course. Because the bit is piloted, you don't have to use the router-table fence. (You should use a starting pin if you don't use the fence J If you do use the fence, set it so it lines up widi the pilot. Hold a straight edge against the fence so it bridges the bit gap. and adjust the fence until the straight edge just touches the pilot bearing.
