Underwater Drills & Hammer Drills

Underwater Drills for All Materials and Applications

EC Hopkins supply a complete range of underwater drills designed to suit virtually any material, drilling depth, or hole diameter required in commercial diving, subsea construction, offshore maintenance, and marine engineering. Our product portfolio includes underwater hammer drills, underwater rock drills, underwater core drills and metal‑drilling solutions, ensuring you always have the right tool for the job.

Underwater Hammer Drills for Concrete, Brick & Stone

For drilling into concrete, masonry, brickwork, and natural stone, the underwater hammer drill is the most effective solution. These tools deliver high impact energy for fast, controlled drilling in tough materials, including both hard and soft bedrock such as granite, chalk and limestone.

We supply the full range of Spitznas underwater hammer drills, including:

• SDS Plus underwater hammer drill
• SDS Max underwater hammer drill

These models offer exceptional power, reliability, and versatility in challenging subsea environments.

Underwater Rock Drills for Deep or Large-Diameter Holes

For demanding underwater rock drilling applications, EC Hopkins offer high‑performance hydraulic rock drills, including:

• Stanley HD45 underwater hammer drill – ideal for drilling into hard rock
• Stanley SK58 underwater sinker drill – suitable for larger holes and greater drilling depths
• Hycon HRD28X hydraulic rock drill – powerful and robust for extended drilling operations

These rock drills are engineered for tough subsea conditions and deliver efficient penetration in rock, bedrock and heavily compacted materials.

Underwater Core Drills for Reinforced and Standard ConcreteWhen drilling holes in reinforced concrete or standard concrete, an underwater core drill provides the accuracy and precision required.

We supply a wide range of hydraulic underwater core drills, including:

• Hopkins CD07 – can be used hand‑held
• Hycon HCD25 and HCD50 – hand‑held or stand‑mounted
• Atlas Copco underwater core drills – versatile and durable
• Spitznas CD10 underwater core drill – suitable for hand or stand operation

Underwater core drills can also be used for material sampling from concrete, rock, coral or other subsea structures.
Alongside standard core bits, we offer special deep‑reach drilling barrels, enabling sample extraction up to 2 metres deep.

Underwater Drilling Solutions for Metal & SteelFor drilling into metal underwater, including steel structures, sheet metal and subsea piles, we offer:

• Stanley DL07 underwater drill – ideal for smaller diameter metal holes
• Hopkins HUW150 underwater broaching cutter with magnetic base – suitable for holes up to 76mm diameter in material up to 75mm thick

With modifications, the HUW150’s drilling capacity can be increased to 100mm diameter, making it a powerful solution for underwater metalworking.

Hydraulic & Pneumatic Underwater Drills AvailableWhile hydraulic underwater drills provide the best performance for most subsea drilling applications, EC Hopkins also offer a selection of pneumatic underwater drills for environments where air-powered tools are preferred.
