1) The shank- the part of the router bit that is
inserted into the collet (the sleeve of the router).
2) The cutting edge- this part cuts and removes the
wood. They are available in several sizes and shapes.
3) The pilot- the guide for the router in order to make
a correct cut. It can be an extension of the shank or a
ball bearing attachment.

The Different Kinds of Router Bits While there are over 50 router bit profiles, here are
the four basic types of router bits: 2) Joinery Bits- Router bits that help make several different types of joints. This type of router bit includes the Finger Joint, the Drawer Lock, the Rile and Stile, and Dovetail Bits. |
3) Edge Bits- Bits used to create different-shaped edges
in woodwork. Examples of these types of bits include the
Beading, Flush, and Round-over bits.
4) Specialized Bits- These bits do not fit into one of
the above categories and have more specialized purposes
including the Key Hole, Raised Panel, and T-Slot bits.
Carbide versus HSS bits
Most of the bits you will find available in hardware stores are carbide (short for tungsten carbide) tipped. These router bits are made of a very hard material that stays sharp longer than steel and is resistant to heat. However, this type of router bit can chip and is very expensive (this is why most of the bits are tipped and not made completely of carbide). High Speed Steel (HSS) bits have been around longer but are not as readily available as the carbide bits. An HSS router bit is not as expensive but will dull fairly quickly. The HSS router bit is more suited for occasional work while a carbide router bit is meant for greater use, lasting 20 times longer than the HSS router bit. How to Take Care of Router Bits To keep your router bit set in good shape, you will want to do small amounts of cutting at a time.

This not only keeps you away from overheating, but will
also extend the life of the router bit. Always use the
shortest and widest bit possible for your project. This
will again prevent overheating and will also avoid
chattering. Always keep your router bits clean and free
from pitch and in good condition to avoid dulling.
Remove any pitch and tar from the router bit (if not
removed, it will cause the bit to unevenly bounce on the
surface). Commercial bit cleaner can be used to remove
pitch and tar; however, a scrap piece of wood will
usually do the trick. This will help keep your router
bits in good working order. The parts of a router bit,
the types of bits, the difference between HSS bits and
carbide bits, and the proper care of router bits are all
important concepts to understand when selecting your own
router bit set. This basic knowledge will help you know
what you need in a router bit set and how to use it
properly.
