Q: What is the Stanley HD45310 Underwater Hammer Drill designed for?
A: It is a heavy-duty hydraulic hammer drill designed for underwater drilling in concrete, rock, masonry, and asphalt, making it ideal for commercial diving and anchor bolt installation.

Q: What is its drilling capacity?
A: It drills holes from 3/4 in. to 2 in. (19–50 mm) in diameter up to 29 in. (73.7 cm) deep and can core drill up to 4 in. (102 mm) in diameter.

Q: What hydraulic flow and pressure does it require?
A: It operates at 7–9 GPM (26–34 LPM) with a working pressure of 1,500–2,000 PSI (105–140 bar). The optimum flow is 8 GPM (30 LPM).

Q: Does it support forward and reverse rotation?
A: Yes. It features adjustable forward and reverse rotation with speeds up to 300 RPM for precise drilling control.
