- Both a standard router and a plunge router have motors (usually
- universal motors between 5 and 15 amps) that are mounted vertically in
- a base. The router bits are attached directly to the motor shaft via
- a collet.
-
- The major difference between the two is that in a standard router the
- bit is always protruding from the bottom by the amount you set, while
- in a plunge router the motor (and bit) can be retracted so that the
- motor can be running with the router in position and yet the bit is
- not cutting into the wood.
-
- This has 1 major advantage--when starting a cut in the middle of a
- board, you don't have to put the router, with the bit turning, on
- edge and then swing it down into the cut (usually resulting in a
- sloppy start of the cut). The bit in a plunge router can be directly
- lowered into the cut.
-
- Plunge routers have become the be all and end all of routers.
- Everyone feels they have to have one. They do have drawbacks, though.
- Probably the biggest is that it is not as easy to make precise depth
- adjustments, especially when mounted under a table. To this end,
- people have resorted to accessories like special knobs that make it a
- little easier to make the adjustments (which are both against the
- weight of the motor and the spring tension). The old fixed-base
- routers are much better for this. The other drawback I've run into is
- that, when using a plunge router in a dovetail jig using a collar
- around the bit, since some dovetail bits are larger than the collar,
- you have to be very careful not to retract the bit or you may damage
- it on the collar.
-
- They are both good tools, but each has good and bad points.
