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.
Claims14
A cutting tool comprising:
- a tool body having a first end defining a rim, a second end, and an axis extending therebetween, the second end being engageable with a spindle of a power tool;
- a gullet 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;
- a first finger formed adjacent the gullet;
- a second finger spaced apart from the first finger, the first finger and the second finger cooperating to define a track that extends around a portion of an opening;
- and
- a blade disposed within the opening and received by the track, the blade including a cutting edge,
- wherein one of the blade and the tool body includes a magnet to at least partially retain the blade in the opening.
A cutting tool comprising:
- a tool body having a first end defining a rim, a second end, and an axis extending therebetween, the second end being engageable with a spindle of a power tool;
- a gullet 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;
- an opening formed adjacent the gullet and defining a track having a V-shaped cross section;
