Abstract
A mixing bit having an elongated shaft configured to fit into a chuck of a drill at a first end also has a second end is provided with a blade assembly having a plurality of specifically shaped and equally-spaced blades. The blades extend perpendicularly from the shaft and then converge onto the shaft at a distal end of the second end. The bit is provided with a rounded spinner feature enabling smooth sliding of the device across a floor portion of a container during mixing.
Claims18
A mixing bit comprising:
- a central shaft, having a first end and a second end, wherein at least said first end has a polygonal cross sectional shape;
- and,
- a blade arrangement disposed on said second end, comprising a plurality of vanes, wherein each vane of said plurality of vanes comprises:
- a first member comprising a first member-first end connected to an intermediate location of said central shaft and an opposing first member-second end, said first member extending perpendicularly outward from said central shaft;
- a second member comprising a second member-first end connected to said first member-second end and an opposing second member-second end, said second member extending downward and depending inward from said first member;
- a third member comprising a third member-first end connected to said second member-second end and an opposing third member-second end, said third member extending downward from said second member and angularly offset from said second member;
- and
- a fourth member comprising a fourth member-first end connected to said third member-second end and an opposing fourth member-second end connecting adjacent to a terminus of said central shaft, said fourth member extending perpendicularly inward from said third member;
- and wherein:
- each vane of said plurality of vanes comprises an overall length, measured along an axis parallel to said central shaft;
- said second member forms a first half of said overall length of said vane;
- and
- said third member forms a second half of said overall length of said vane.
