Handheld Diamond Core Drills

Diamond core drills excel is accurate drilling and tackling exceptionally hard applications where other drills fail. Featuring dry or wet drilling functionality, diamond core drills are particularly popular for plumbers when drilling holes for boiler flues or pipework.

A handheld diamond core drill is a compact, portable core drill designed for drilling precise, clean holes in tough materials such as concrete, masonry, and stone. Unlike larger drill rigs, handheld models are lightweight and versatile, making them ideal for on-the-go use in tight spaces or smaller projects.

A drill rig is a stationary system typically used for larger and deeper drilling tasks, requiring a stable setup for accuracy. In contrast, handheld diamond core drills are portable and manually operated, offering flexibility for smaller or more accessible drilling jobs. While a drill rig provides maximum stability and precision, handheld models excel in convenience and mobility.

• Portability: Easy to carry and use in various locations, including confined spaces.
• Versatility: Suitable for smaller to medium-sized holes in hard materials.
• Cost-Effective: Lower cost than a drill rig for less intensive tasks.
• Ease of Use: Quick setup and operation without the need for extensive equipment.

Yes, many handheld diamond core drills, such as the EIBENSTOCK ETN 162/3, feature variable speed settings. This allows users to adjust the drill’s speed based on the material and drilling conditions, ensuring precision and prolonging the lifespan of the drill bit.

Handheld diamond core drills typically weigh between 5 and 10 kilograms, depending on the model and its features. Every EIBENSTOCK core drill is designed to strike a balance between power and portability, making them suitable for professional use without excessive strain.

The EIBENSTOCK ETN 162/3 is an exceptional choice for professionals, offering powerful performance, variable speed options, and a robust build. It features a 2200w motor, integrated dust extraction, soft start trigger control and top and side spirit level bubbles.

The maximum hole size depends on the drill's specifications. Some of our best selling handheld diamond core drills, including the EHD 2002 core drill can drill up to 152mm while others such as the ESD 162 soft percussion diamond drill can drill up to 202mm.

A clutch is a safety mechanism designed to disengage the drill's drive system when excessive torque is detected. This prevents the drill from spinning out of control if the drill bit becomes stuck or encounters heavy resistance.

Yes, a safety clutch is highly recommended for core drilling. It protects both the operator and the equipment by minimising the risk of sudden, uncontrolled movements, particularly when working with hard materials.

Safety clutches can prevent:

• Kickback Injuries: Sudden jerks caused by bit jams.
• Tool Damage: Overloading and overheating the motor.
• User Strain: Excessive torque transferred to the operator.

No, not all diamond core drills include a safety clutch. However, high-quality models like those from EIBENSTOCK come equipped with this feature to ensure user safety and extend the tool’s lifespan.

Yes, safety clutches vary in design and operation, such as:

• Mechanical Clutches: Automatically disengage when torque exceeds a set limit.
• Electronic Clutches: Use sensors to detect excessive torque and shut off the motor.
