Abstract
A cutting device in accordance with some example embodiments is provided for use with an arbor assembly. The cutting device includes a blade having a plurality of teeth, and a back plate at a proximal end of the blade. The back plate has an outer end surface in which a plurality of ramp surfaces and pin locking recess are provided. A central through hole extending through the back plate. The ramp surfaces only allow the cutting device to be rotated relative to the arbor assembly in one direction.
Claims14
A cutting device for use with an arbor assembly comprising:
- a blade having a proximal end and a distal end, and a plurality of teeth at the distal end thereof;
- and
- a back plate at the proximal end of the blade,
- the back plate having a proximal end and a distal end, the proximal end of the back plate forming an outer end surface,
- a central through hole extending from the proximal end to the distal end of the back plate, the central through hole having alternating threaded wall portions and unthreaded wall portions which extend from the proximal end to the distal end of the back plate
- a first pin engaging ramp having side walls extending distally from the outer end surface and a sloped base wall extending between the side walls, the first pin engaging ramp being spaced apart from the through hole,
- a first pin locking recess having a side wall extending distally from the outer end surface and an end surface at a distal end thereof, the first pin locking recess being spaced apart from the through hole, the first pin locking recess being spaced apart from the first pin engaging ramp by a first surface portion of the outer surface,
- a second pin engaging ramp having side walls extending distally from the outer end surface and a sloped base wall extending between the side walls thereof, the second pin engaging ramp being spaced apart from the through hole, and
- a second pin locking recess having a side wall extending distally from the outer end surface and an end surface at a distal end thereof, the second pin locking recess being spaced apart from the through hole, the second pin locking recess being spaced apart from the first pin engaging ramp by a second surface portion of the outer surface, the second pin locking recess being spaced being spaced apart from the second pin engaging ramp by a third surface portion of the outer surface,
- wherein the pin engaging ramps only allow the cutting device to be rotated relative to the arbor assembly in one direction to engage the cutting device with the arbor assembly.
