• a chuck housing defining a plurality of channels;
• a plurality of self-centering jaws bases disposed within the plurality of channels,
• wherein the plurality of self-centering jaws bases comprise at least one jaws base hole,
• wherein each of the plurality of channels is accessible through a circumferential perimeter of the chuck housing enabling at least a portion of the self-centering jaws bases to extend past the circumferential perimeter,
• wherein each of the plurality of self-centering jaws bases includes one or more circular indicators,
• wherein each of the channels includes one or more ridges disposed along a length of each channel, and
• wherein each of the plurality of self-centering jaws bases has an I-shaped cross section configured to interface with the one or more ridges;
• a scroll wheel in mechanical communication with the plurality of self-centering jaws bases,
• wherein the scroll wheel comprises a plurality of protrusions extending radially from a circumference of the scroll wheel beyond the circumference of the chuck housing;
• and
