We would like to clear up some confusion on the maximum depths allowed for certain bits (specifically the carving and cutting bits). The maximum cut depth as stated in the Operator's manual is 1" for the straight 1/8" cutting bit. The maximum carving depth for the 1/16" tapered carving bit is 3/4" because that is the length of the sharpened flutes. This max depth rule applies to all bits; you cannot carve deeper than the length of the sharpened cutting surface. If you program the project to go deeper than 3/4" with the carving bit you will most likely damage your machine or bits since the stress on the machine increases exponentially when the bit is not cutting.
