DEPTH OF CUT

See Figure 22.

As previously mentioned, the depth of cut is important because it affects the rate of feed that, in turn, affects

the quality of the cut (and, also, the possibility of damage to the router motor and bit). A deep cut requires a slower feed than a shallow one. A cut that is too deep causes you to slow the feed so much that the bit no longer cuts; instead it scrapes.

Making a deep cut is never advisable. The smaller bits---especially those only 1/16 inch (1.6 mm) in diameter--are easily broken off when subjected to too much side thrust. A large enough bit may not be broken, but if the cut is too deep a rough cut will result--and it may be very difficult to guide and control the bit as desired. For these reasons, we recommend that you do not exceed 1/8 in. depth of cut in a single pass, regardless of the bit size or the softness or condition of the workpiece.

Therefore, to make deeper cuts, make many successive passes, Iowedng the bit 1/8 in. for each new pass. In order to save time, do all the cutting necessary at one depth setting before lowering the bit for the next pass. This also assures a uniform depth when you complete the final pass.
