Abstract
A shell cutter tool can include an arbor; a cutter including a first end secured to the arbor; a second end defining a cutting element; and a wall extending from the first end to the second end and defining an inner surface and an outer surface, the outer surface defining an outer diameter of the cutter; and a depth stop secured to the cutter, the depth stop defining a stop surface and an outer diameter, the outer diameter of the depth stop being greater than the outer diameter of the cutter.
Claims6
A shell cutter tool for cutting an opening in a workpiece, the tool comprising:
- an arbor;
- a cutter comprising:
- a first end secured to the arbor;
- a second end defining a cutting element;
- and
- a wall extending from the first end to the second end and defining an inner surface and an outer surface, the outer surface defining an outer diameter of the cutter;
- and
- a depth stop comprising a stop ring defining an annular shape defining an inner surface defining threads, the threads engaged with threads defined in the outer surface of the wall of the cutter, the depth stop being axially translatable relative to the cutter to adjust a cut depth of the tool, the depth stop defining a stop surface and an outer diameter, the outer diameter of the depth stop being greater than the outer diameter of the cutter, the stop surface configured to contact the workpiece;
- wherein:
- a radially inner side of the stop ring defines a first axial thickness;
- a radially outer side of the stop ring defines a second axial thickness;
- and
- the first axial thickness is less than the second axial thickness.
