## Narrative

While changing a bit on the DTH drill a supplier was unscrewing the chuck and bit from the bottom of the hammer, the bit slipped and while trying to stabilize it the supplier's small finger moved in between the chuck and the top shoulder of the bit. The chuck came down on the smallest finger of the left hand causing a laceration under the glove.
