These miniature tools are big in strength yet small enough to get into those tight spots. High quality steel ratchet holds any one of the many hardened steel bits.

This 9-piece Chapman Metric Hex Bit Set includes a mini ratchet CM-13, one Spinner and seven Metric Allen hex insert bits (1.5mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm) packed in a heavy duty vinyl case.
