Professional Cordless Power — Engineered for Concrete, Masonry & Beyond
- High-Torque Brushless Motor with 20V Li-Ion Power: The IDU HD-B26 runs on a 20V lithium-ion brushless motor that eliminates carbon brush friction, converting more energy directly into torque. The result is a tool that runs cooler, lasts longer between services, and delivers consistent rotational power at 0–1,100 RPM — ideal for sustained drilling sessions on tough substrates.
- 2.7J Impact Energy at 0–4,300 Impacts Per Minute: With 2.7 joules of single impact energy and a variable impact frequency of up to 4,300 bpm, the HD-B26 penetrates concrete and masonry with authority. The 26mm masonry drilling capacity, 30mm wood capacity, and 13mm steel capacity make this a genuinely versatile multi-material tool.
- 4-Mode Function Selector for Maximum Versatility: A clearly marked 4-position mode dial switches between Rotary Drilling (wood/steel), Hammer Drilling (concrete/masonry), Chiseling (demolition/tile removal), and Driving (fastening) — eliminating the need for multiple tools on site and reducing tool changeover time.
- SDS-Plus Shank with Keyless Chuck System: The 10mm SDS-Plus chuck accepts the industry-standard SDS-Plus bit range, enabling tool-free bit changes in seconds. The keyless collar design means no chuck key to lose on site, and the positive-lock mechanism ensures bits are held securely under full hammer load — critical for safety and drilling accuracy.
- Anti-Vibration Design with Variable Speed Trigger and Forward/Reverse Control: The integrated anti-vibration system absorbs hammer recoil at the handle, significantly reducing hand-arm vibration exposure during prolonged use. Combined with a variable speed trigger (squeeze harder for higher RPM) and a forward/reverse switch, the operator has precise control for both drilling and extraction in all materials.
- 4.0Ah Battery with LED Charge Indicator and Double Insulation Safety: The included IDU BT20-4A 4,000mAh 20V lithium-ion battery provides extended runtime on a single charge, with an onboard LED battery level indicator so you always know your remaining capacity. The tool's double insulation construction ensures the internal electrical components are fully isolated from the outer housing — a critical safety feature for wet or dusty environments. The kit includes the IDU CH60-2A 2.4A standard charger fitted with a Type G (British 3-pin) plug, compatible with UAE, UK, and GCC 220–240V supplies.
- Complete Kit with PVC Carrying Case and Full Accessory Set: The HD-B26 ships as a complete cordless kit including an auxiliary side handle for two-handed control, a depth gauge rod for consistent hole depths, a 110mm SDS drill bit set (6/8/10mm), a set of pointed and flat chisels (13 x 145mm), and a rigid PVC carrying case for organised, protected storage and transport on site.
The IDU HD-B26 carries CE certification (comprehensive machine safety test to European standards), CB certification (international comprehensive machine test for global market compliance), and RoHS certification (raw materials test confirming restriction of hazardous substances) — ensuring the tool meets rigorous safety and environmental standards for professional use. The kit includes the machine, auxiliary handle, depth gauge, 4A 20V Li-Ion battery (IDU BT20-4A), 2.0A standard charger (IDU CH60-2A), PVC carrying case, 110mm SDS drill bit set (6/8/10mm), and pointed and flat chisels (13 x 145mm), along with a guide book — everything needed to start work immediately out of the box.
General Purchase & Comparison Queries
Is the IDU HD-B26 a brushed or brushless rotary hammer, and why does it matter?
The IDU HD-B26 uses a brushless motor, which is a significant advantage over brushed alternatives. Brushless motors eliminate the carbon brushes that create friction and heat in traditional motors, meaning more of the battery's energy is converted into usable torque rather than wasted as heat. In practical terms, this translates to longer runtime per charge, higher torque output, reduced maintenance (no brushes to replace), and a longer overall tool lifespan — making it the preferred choice for professional and frequent use.
What is included in the kit, and do I need to buy a battery separately?
The IDU HD-B26 is sold as a complete cordless kit — no separate battery purchase is required. The kit includes the rotary hammer machine, a 4.0Ah 20V Li-Ion battery (IDU BT20-4A), a 2.0A standard charger (IDU CH60-2A) with a Type G (British 3-pin) plug, an auxiliary side handle, a depth gauge, a 110mm SDS drill bit set (6/8/10mm), pointed and flat chisels (13 x 145mm), a PVC carrying case, and a guide book. Everything needed to begin work is included out of the box.
Is the charger compatible with UAE and GCC power outlets?
Yes. The included IDU CH60-2A charger operates on 220–240V AC at 50/60Hz and is fitted with a Type G British 3-pin plug, which is the standard plug type used across the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, Oman, and the wider GCC region, as well as the UK. No adapter is required for use in these markets.
Product-Specific and Usage Queries
What are the four function modes and when should I use each one?
The HD-B26 features a 4-position mode selector for maximum versatility: Rotary Drilling is used for drilling into wood (up to 30mm) and steel (up to 13mm) without hammering action; Hammer Drilling combines rotation with impact for drilling into concrete, brick, and masonry (up to 26mm); Chiseling disengages rotation and uses impact-only action for breaking tiles, removing render, or light demolition; and Driving mode is used for fastening screws and bolts. Selecting the correct mode protects both the bit and the material surface.
What size SDS-Plus bits does the HD-B26 accept, and what drill capacities does it support?
The HD-B26 is fitted with a 10mm SDS-Plus chuck that accepts the standard SDS-Plus shank bit range — the most widely available SDS bit format globally. The tool supports a masonry drilling capacity of 26mm, a wood drilling capacity of 30mm, and a steel drilling capacity of 13mm. The kit includes a 110mm SDS drill bit set in 6mm, 8mm, and 10mm diameters, as well as 13 x 145mm pointed and flat chisels to get you started immediately.
How does the anti-vibration system work, and is it important for daily use?
The HD-B26's anti-vibration system is built into the tool's handle and internal mechanism to absorb and dampen the recoil generated by the hammer action during drilling and chiseling. For professionals using a rotary hammer for extended periods, unmanaged vibration leads to hand-arm vibration syndrome (HAVS) — a cumulative condition that affects circulation and nerve function. By reducing the vibration transmitted to the operator's hands, the HD-B26 allows for longer, more comfortable working sessions and helps meet occupational health standards on professional job sites.
Problem/Solution-Oriented Queries
The drill bit is not penetrating concrete efficiently — what should I check?
If the HD-B26 is struggling to penetrate concrete, first confirm the mode selector is set to Hammer Drilling (not Rotary Drilling). Next, check that you are using a sharp SDS-Plus masonry bit — worn bits dramatically reduce penetration rate. Ensure the bit is fully seated and locked in the SDS-Plus chuck. Apply firm, steady forward pressure without forcing the tool. If the battery indicator shows low charge, recharge the IDU BT20-4A battery before continuing, as reduced voltage directly impacts impact frequency and energy output. For very hard aggregate concrete, a larger-diameter bit may require slower, more deliberate progress.
The tool feels excessively heavy during overhead drilling — how can I manage fatigue?
At 4.22kg including battery and charger, the HD-B26 is a professional-class tool with a weight appropriate for its power output. For overhead drilling, always attach the included auxiliary side handle to distribute the load between both arms and improve control. Use the depth gauge rod to pre-set your required hole depth so you are not over-drilling. Take regular breaks to allow muscles to recover, and use the variable speed trigger to start holes at low speed before increasing RPM — this reduces the initial torque reaction that strains the wrists. The tool's compact design and balanced weight distribution are specifically engineered to minimise fatigue relative to its power class.
The LED battery indicator is showing low charge quickly — is this normal?
Battery runtime depends heavily on the application. Hammer drilling into dense concrete is one of the most energy-intensive tasks a cordless tool performs, and will deplete the 4.0Ah 20V battery faster than lighter drilling tasks. If runtime seems shorter than expected, ensure the battery is being fully charged before use using the IDU CH60-2A charger. Avoid storing the battery in extreme heat or direct sunlight, as lithium-ion cells degrade faster under thermal stress. If the battery is new and runtime is still very short, contact your IDU authorised service centre, as the battery may have a manufacturing defect covered under warranty.
