Direction of Feed for Internal Cuts (Fig. 27b)  
Fig. 27c  
When making an internal cut, such as groove,  
dado, or slot, always position the guide (edge  
guide, straight edge, or board guide) on the  
right-hand side of the tool as the cut is made.  
Feeding too quickly  
Always be alert and exercise extreme caution  
in order to maintain control of the tool when  
making this type of cut around curves.  
In either case, the lateral thrust of the cutting is  
always against the guide, as is proper.  
Always clamp the workpiece  
WARNING  
securely and keep a firm grip  
Fig. 27d  
on the tool base with both hands at all times.  
Failure to do so could result in loss of control,  
causing possibly serious personal injury.  
Feeding too slowly  
Rate of Feed  
The proper rate of feed depends on several  
factors: the hardness and moisture content of  
the workpiece, the cutting depth, and the cutting  
diameter of the bit. Use a faster rate of feed  
when cutting shallow grooves in soft woods,  
such as pine. Use a slower rate of feed when  
making deep cuts in hardwoods, such as oak.  
Kickback may damage the workpiece and  
could result in losing control of the tool, causing  
possible personal injury.  
Feeding too quickly (Fig. 27c)  
Forcing the feed of the cutter bit forward  
too quickly slows the rotational speed of the  
cutter bit and the bit takes larger bites as it  
rotates, causing splintering and gouging of the  
workpiece. This forcing action can also cause  
the router motor to overheat.  
Feeding too slowly (Fig. 27d)  
When the cutter bit is fed too slowly, the rotating  
cutter bit does not cut into new wood rapidly  
enough to take a bite. Instead, it scrapes away  
sawdust-like particles. This scraping produces  
heat, which can glaze, burn, and mar the cut  
in the workpiece, and in extreme cases, can  
overheat the cutter bit.  
The high speed of the cutter bit during a proper  
feeding operation (left to right) results in very  
little kickback under normal conditions.
