[Coral-List] Underwater Drill

  Vone Research has used inexpensive (about $30.00) pneumatic drills from Home Depot attached to the low pressure side of the regulator which was then attached to SCUBA tanks to drill holes in cement underwater.  The tank does not last long; however, we were drilling 1/2 inch holes 6 to 8 inches deep. It took a tank that held 80 cubic feet of air to drill 3 holes of that diameter.  We cut an inflator hose and clamped a quick release valve onto it with a hose clamp and attached that to the drill.
  The drill will only work 1 to 2 days, and should be soaked in fresh water after use in salt water.
  If you would like further assistance, please feel free to contact us-

  Dear A.J.

If you still want to drill underwater by using a hand-pneumatic drill,
You may refer to:
Adachi and Abe (2003) "Air drill" for submerged massive coral 
drilling. Mar. Tech. Soc. J., 37(2) 31-36.
