Bits are to be used for underwater drilling of rock for a harbor deepening project in Ogdensburg, NY. Anticipated hole diameter is 4-1/2\". Total lf of holes to be drilled in hard overburden and rock is approximately 41,300 lf. I was unsure if a sealed or non sealed bearing would be required. If the above product quote request does not meet the drilling requirements please substitute for the nearest item that meets the requirements.rnrnThank You rnJim
