What is a compression bit?
A compression bit is the combination of both upcut and downcut spirals. Typically, a compression spiral has an upcut single, double or triple flute at the tip of the cutter, approximately one third of the cutting length. The remaining two thirds is ground to give a downcutting shear.
By combining both geometries, you achieve a win/win situation. The bottom of the material is pulled upwards while the top of the material is pushed downwards thus eliminating the risk of damaging the laminated surfaces. When run at full depth, the bit leaves a sharp, clean edge on both sides of your workpiece.
A compression bit can be a little more expensive than standard router bits, we recommend them as an essential tool when processing double laminate wood materials.
