Dirt or dust buildup on the tool holders. Look for dark spots on the surface of the
tool holder, this will indicate a buildup of residue.

Metal cuttings lodged in the tool or the collet.

Metal cuttings lodged in the tool will cause “Halos” or circular scratches in
paint and stainless steel. Remove any that collect in the collet or drill
flutes.
