- 500W Motor with 1.7J Impact Energy at 0–3,900 BPM: The HD2-20SRE delivers a rated power input of 500 watts and a maximum impact energy of 1.7 joules, cycling at up to 3,900 blows per minute. Combined with a no-load speed of 0–850 r/min, this translates to fast, clean penetration in concrete and masonry with minimal operator fatigue — ideal for repetitive anchoring and core drilling tasks on active job sites.
- SDS-Plus Shank System for Rapid, Tool-Free Bit Changes: Equipped with a 10mm SDS-Plus chuck, the HD2-20SRE accepts the industry-standard SDS-Plus bit range, enabling tool-free bit insertion and removal in seconds. Maximum drilling capacities reach 20mm in concrete, 13mm in steel, and 30mm in wood, with an optimum drilling range of 4–12mm for everyday anchoring and fixing work.
- Variable Speed Trigger with Lock-On Button for Precision and Endurance: The variable speed trigger provides proportional speed control — squeeze lightly for accurate spot-start drilling, squeeze fully for maximum penetration rate. The integrated impact lock-on button maintains consistent full-speed operation during extended, high-volume drilling runs, reducing hand fatigue and improving productivity on large-scale installations.
- 360° Rotating Auxiliary Handle with Depth Gauge for Repeatable Accuracy: The soft-grip auxiliary handle rotates a full 360 degrees and locks securely at any angle, giving operators optimal tool control in confined spaces or overhead applications. The included depth gauge rod sets a precise drilling depth stop, ensuring every anchor hole is drilled to the exact required depth — critical for structural fixings and facade work.
- Double Insulation, Forward/Reverse Control & Auto-Stop Carbon Set: Built with double insulation to prevent electrical contact between internal components and the outer casing, the HD2-20SRE meets stringent safety standards. The forward and reverse switch allows effortless bit extraction from binding materials, while the included auto-stop carbon brush set automatically cuts motor power when brushes wear to their service limit — protecting the motor from damage and extending tool life.
- Compact 2.6 kg Body with PVC Carrying Case for Site Mobility: Weighing just 2.6 kg, this compact rotary hammer reduces arm strain during overhead and vertical drilling. The complete kit ships in a rigid PVC carrying case that houses the machine, auxiliary handle, depth gauge, safety gloves, a set of 6/8/10mm drill bits, auto-stop carbon set, and guide book — keeping every component organised and protected between jobs.
This machine carries CE (Machine Test) certification confirming compliance with European machinery safety directives, GS (Geprüfte Sicherheit) certification independently verifying product safety beyond the minimum legal requirements, and EMC (Production Inspected) certification ensuring the tool does not generate or succumb to electromagnetic interference in professional environments. In the box you will find the HD2-20SRE machine, a comprehensive guide book, one pair of auto-stop carbon brushes, the 360° auxiliary handle, a depth gauge rod, one pair of safety gloves, a three-piece SDS-Plus drill bit set (6 mm, 8 mm, and 10 mm), and the protective PVC carrying case — everything required to begin work immediately upon delivery.
General Purchase & Comparison Queries
Is the ID HD2-20SRE compatible with standard UK and UAE power outlets?
Yes. The HD2-20SRE is rated at 220–240V, 50/60 Hz and ships with a Type G (British 3-pin) plug, making it immediately compatible with UAE, UK, and most GCC power outlets without the need for an adapter or converter.
How does this compare to a standard drill driver — do I need a rotary hammer?
A standard drill driver relies solely on rotary motion and is suited for wood and soft materials. The HD2-20SRE adds a pneumatic hammer mechanism delivering 1.7 joules at up to 3,900 BPM, which is essential for efficient drilling into concrete, brick, and masonry. If your work involves anchoring into hard substrates, a rotary hammer is the correct tool — a standard drill will wear out prematurely and produce poor results.
What certifications does this machine hold and why do they matter?
The HD2-20SRE holds CE (Machine Test) certification for compliance with EU machinery safety directives, GS (Geprüfte Sicherheit) certification — an independent German safety mark that exceeds minimum legal requirements — and EMC (Production Inspected) certification confirming the tool operates without causing or suffering electromagnetic interference. These marks provide assurance of build quality and regulatory compliance for professional and commercial use.
Product-Specific and Usage Queries
What is the maximum drilling capacity and what bit shank does it use?
The HD2-20SRE accepts SDS-Plus (10mm shank) bits and delivers a maximum drilling capacity of 20mm in concrete, 13mm in steel, and 30mm in wood. The optimum working range is 4–12mm, covering the vast majority of anchor bolt, rawlplug, and cable conduit drilling tasks encountered on construction and fit-out sites.
Can I use this machine for drilling into wood and metal as well as concrete?
Yes. The 2-mode multi-function operation allows you to switch between Rotary Drilling mode — for clean boring into wood, metal, ceramics, and plastics — and Hammer Drilling mode for synchronized rotation and pneumatic impact into concrete and masonry. Simply select the appropriate mode for the material and fit the correct SDS-Plus bit.
How do I set a consistent drilling depth with this machine?
The included depth gauge rod slides into the auxiliary handle collar and is secured at your required depth measurement. Once set, the rod contacts the work surface when the bit reaches the target depth, preventing over-drilling. This is particularly useful when installing anchor bolts, shelf brackets, or electrical back-boxes that require a precise embedment depth.
Problem/Solution-Oriented Queries
The drill bit keeps getting stuck in the material — what should I do?
Use the forward/reverse switch to reverse the rotation direction, which will free a bound or jammed bit without damaging the chuck or the workpiece. Avoid forcing the tool forward when resistance increases — reduce pressure, allow the hammer mechanism to do the work, and use the reverse function as needed. Ensure you are using the correct SDS-Plus bit rated for the material and diameter you are drilling.
The tool stopped running mid-use — what could be the cause?
The most likely cause is the auto-stop carbon brush system activating, which automatically cuts power to the motor when the carbon brushes reach the end of their service life — a built-in protection feature that prevents motor burnout. Replace the carbon brushes (a spare set is included in the kit) and the tool will resume normal operation. If the tool stops immediately after starting, check that the power supply is stable at 220–240V and that the plug and cable are undamaged.
The machine vibrates excessively and is difficult to control — how can I improve handling?
Reposition and lock the 360° rotating auxiliary handle to a grip angle that gives you balanced two-handed control for your specific drilling direction — horizontal, vertical, or overhead. Ensure the handle quick-lock is fully tightened. Use the variable speed trigger to start at a lower speed when beginning a hole to prevent the bit from skating across the surface, then increase speed once the bit is seated. Always wear the included safety gloves to reduce transmitted vibration to your hands during extended use.
