BitBuddie

The BitBuddie is a tool designed to keep the drill in where its supposed to be, and pull the dust out  while you work. 2 sizes available: 1-3/8 and cut  your own size up to 4".  The shrouds are held down with vacuum so these need to be used with a wet  & dry vacuum.   The 1-3/8 is real small so its great for drilling the faucet hole behind the sink.
