⚡ At a Glance

• Torque & Speed: 120 N·m (1060 in·lbs) maximum torque, Low 0–600 RPM / High 0–2150 RPM
• Developed for: DIY homeowners and part-time tradespeople who switch between screwdriving, woodwork and light masonry
• Potential hurdles: Contractors drilling dozens of deep 12 mm holes in reinforced concrete; the dual 4.0Ah cells will deplete during long runs and the 2–3 hour recharge plus overload pauses interrupt continuous on-site progress

A 21V brushless hammer drill with 20+3 clutch settings and three operation modes. Supplied with two 4.0Ah batteries, fast charger and a full accessory kit for mixed DIY and repair tasks.

Consistent Drilling Power: The 120N·m Role

The brushless 21V motor delivers up to 120 N·m (1060 in·lbs), keeping torque steady when the bit meets resistance and preventing stalls on larger fasteners or denser materials. Motor overload protection at 55A pauses the tool if temperatures climb, then allows a safe restart once cooled.

Steady torque lets larger-diameter bits bore through timber and brick with fewer snatches. Reduces vibration and keeps starts accurate thanks to the balanced weight and auxiliary handle.

Why DIYers Needs the Dual-Battery System

Two 4.0Ah cells supply roughly two hours of continuous operation between charges and the fast charger returns a depleted cell to full in about 2–3 hours, so swapping cells keeps small teams moving. The 60A battery management board prevents overcharge and overdischarge, protecting the cells during heavy use.

If you face a day of mixed drilling and fastening, then a spare cell keeps the job flowing without hunting for mains power. On-site convenience increases because the compact case stores both cells and the charger for easy transport.

❓ Frequently Asked Questions

Q: What happens when the motor overloads during heavy drilling?

A: Motor overload protection pauses operation automatically to prevent damage, and the tool can be reset after a short cooling period. Pro-tip: keep the cooling vents clear of dust and give the motor five to ten minutes to stabilise before resuming to avoid repeated cut-outs.

Q: What size shank does the chuck accept?

A: The 1/2" (13 mm) self-locking metal chuck accepts standard round-shank bits and sockets for general drilling and screwdriving. Pro-tip: use matched shank bits for hammer drilling to reduce bit wobble and extend bit life.

Q: Is the kit convenient to move between jobs?

A: A portable case is included to store the tool, spare cells and the charger for straightforward transport. Pro-tip: pack spare fasteners and a small bit roll in the case to keep everything you need to hand on site.
