There are several reasons for making 
multiple passes with edge forming, profile 
cutters. 

► 

For large profiles, a shallow first-pass 
can be made to remove the bulk of the 
material.  

► 

Several shallow passes can be made for 
better control with large router bits. 

► 

A final, shallow, clean-up pass can 
improve the quality of the finished edge. 

 

 

 

Altering the horizontal position of a router 
cut for multiple passes is required 
whenever the profile cuts back into the 
workpiece in a way that changing the 
depth would destroy the desired profile. A 
common example of this is a slot cutter. A 
common problem with this type of cutter is 
that sharp corners between the cut profile 
and the uncut wood edge will tend to tear 
out. This can be reduced by making a very 
shallow scoring cut before making a full 
profile cut. 

 

 

 

 

Dovetail and keyway cutters are inherently weak 
because the upper shank of the bit is smaller 
than the cutting edges. If the stress on the bit is 
too great, the cutting tip can break. To reduce 
the stress on the cutter, it is common practice to 
plough out the majority of the material with a 
straight bit. The depth of the straight bit should 
be slightly shallower than the depth of the final 
bit so the bottom of the profile remains square.
