They pull the sister chromatids (the duplicate chromosomes of the cell) apart to opposite poles of the cell allowing new cells to form. Basically they rip the chromosomes in half so there is an equal copy of ever chromosome.
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
Chromosomes line up at the equator of the spindle during the metaphase stage of mitosis. This is when the chromosomes are maximally condensed and are attached to the spindle fibers at their centromeres.
The cellular component that helps pull apart the chromosome in mitosis and meiosis are the spindle fibers. These spindle fibers are made of micro-tubules.

During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
During the metaphase stage of mitosis, the chromosomes become attached to the spindle apparatus.
Spindle fibers attach to chromosomes during metaphase of mitosis. Special protein structures called kinetochores on the chromosomes interact with the spindle fibers to ensure proper alignment and segregation of the chromosomes during cell division.
Chromosomes attach to spindle fibers during metaphase of mitosis. This is when the chromosomes align at the cell's equator, forming a metaphase plate. The spindle fibers attach to the centromere region of the chromosomes.

Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
The stage of mitosis when spindle fibers attach to the centromeres of sister chromatids is called metaphase.
Chromosomes line up at the equator of the spindle during the metaphase stage of mitosis. This is when the chromosomes are maximally condensed and are attached to the spindle fibers at their centromeres.
The answer is telophase.
