Abstract
A cutting tool includes a tool body having a first end engageable with a workpiece and a second end engageable with a spindle of a power tool. A blade extends outwardly from the first end of the tool body and including a cutting edge, the cutting edge being engageable with a workpiece to cut the workpiece. A bit, including a drive shaft and a cutting end extends along an axis of the tool body. The drive shaft extends axially outwardly beyond the first end of the tool body and terminates at the cutting end. The cutting end has a maximum cross-sectional width greater than a maximum cross-sectional width of the drive shaft, and an axial distance from the first end of the tool body to the cutting end is greater than a maximum cutting depth of the cutting tool.
Claims6
A cutting tool comprising:
- a tool body having a first end, a second end, and an axis extending therebetween, the second end being engageable with a spindle of a power tool, the first end terminating in a substantially planar rim;
- a plurality of gullets formed in the tool body and including an open end open at the rim and a closed end disposed adjacent the second end of the tool body, the plurality of gullets spaced equally about the circumference of the tool body;
- a plurality of blades, each blade extending outwardly from the first end of the tool body and attached to the tool body adjacent the open end of one of the gullets such that every other gullet includes a blade disposed adjacent thereto, each blade including a cutting edge, the cutting edge being engageable with a workpiece to cut the workpiece, the cutting edge being spaced a first distance from the second end of the tool body;
- and
- a bit including a drive shaft and a cutting end, the drive shaft extending axially outwardly beyond the first end of the tool body and terminating at the cutting end, the cutting end having a maximum cross-sectional width greater than a maximum cross-sectional width of the drive shaft, and wherein the cutting end is spaced a second distance from the second end of the tool body, the second distance being greater than the first distance.
