Double ended or sheeter drill bits are excellent for thin gauge materials such as sheet metal. Commonly used in automotive and truck body fabrication as well as truck and trailer repair. The short overall length provides added rigidity and the double cutting ends allows for twice the longevity of a single ended drill bit. When the first cutting edges dull on one side, simple flip over to use the sharp side.
