## Narrative

A millwright was working outside of the maintenance shop on a hopper that the millwright was building for the CKD briquetter.  While drilling a pilot hole for a liner, a 1/8"" drill bit broke.  Once the 1/8"" drill bit broke, it pierced the leather gloves at the seam.  The seam was between the thumb & index finger.  The drill bit went into millwright's flesh about 1/4"" deep.
