High-impact rotary hammers engineered for demanding construction sites. Experience superior drilling and chiseling performance with industry-leading vibration control.
You’re not alone. If you’ve been sourcing cordless rotary hammers for your market, you’ve likely run into these frustrating customer complaints:
Weak Drilling Power: The specs promise high Joules, but the tool struggles to drill into hard concrete or stone, taking forever to finish a simple hole.
Battery Drain & Heat: Heavy hammering drains batteries rapidly, triggers thermal protection halfway through a job, or shortens the battery lifespan dramatically.
Mechanism Failures: Piston leaks, gear stripping, or failing SDS chucks that freeze under heavy vibration—leading to high return rates and warranty hassle.
Painful Vibration: Excessive kickback and harsh vibration that numb the operator’s hands quickly, paired with heavy designs that make overhead drilling exhausting.
The real challenge? Finding a cordless rotary hammer that hits with real impact energy — without wearing out the user or destroying its own motor.
Explore our high-performance range of cordless rotary hammer drills, engineered to tackle demanding masonry, concrete, and heavy-duty demolition applications. Powered by robust 21V brushless motor technology and fitted with SDS-Plus chuck systems, this versatile series combines impressive impact energy with active vibration control and safety clutches to boost job site efficiency and operator protection.
It operates more quietly, offers a longer service life, and requires less maintenance, ensuring reliable and stable performance.
Features a conveniently located mode switch for 3 key operations: Drilling Mode (wood and metal), Hammer Drilling Mode (heavy masonry and reinforced concrete), and Chiseling Mode (tile removal and light wall demolition), delivering complete versatility across multiple construction scenarios.
Spend less time on maintenance and more time working. Our intuitive one-touch chuck system allows for lightning-fast, secure bit changes with a single motion.
Achieve the perfect angle every time. The chisel rotates 360° with 40 locking positions, providing maximum control for detailed demolition and shaping tasks.
Designed for the professional user, the contoured shape combined with a premium non-slip coating minimizes vibration and fatigue, ensuring comfort even during the most demanding, prolonged work sessions.
The ergonomic shape and non-slip coating ensure comfort even during prolonged work sessions.
Ensure that the scissors have a long autonomous runtime and can charge quickly.
Will your users handle light masonry drilling — or heavy-duty chiseling?
Will your users only need hole drilling — or additional chiseling capability?
Will your users prioritize competitive pricing — or all-day operator comfort?
Will your users need quick light-duty tasks — or non-stop, swap-and-go jobs?
Are you offering a product — or a complete user experience?

Let’s talk — and get you the performance your customers expect.
Regular Hammer Drill: Uses spinning discs to make small, fast vibrations. Good for light brick or small holes.
Rotary Hammer: Uses a pneumatic piston mechanism to deliver heavy, powerful pounding forces. Essential for drilling large holes into hard concrete, stone, or brick with ease.
"SDS" is the quick-change chuck system that holds the drill bit:
SDS-Plus (Light & Medium Duty): Uses smaller bits (usually under 1 inch / 28mm). Perfect for everyday concrete anchor holes, HVAC installs, and general remodeling.
SDS-Max (Heavy Duty Industrial): Uses thick, heavy bits (over 1 inch / 28mm). Made for breaking heavy concrete, foundation drilling, and major demolition.
Drill Mode (Rotation Only): For drilling into wood, metal, or plastic (requires an extra chuck adapter).
Hammer Drill Mode (Rotation + Hammering): For drilling anchor holes into concrete, stone, and brick.
Chiseling Mode (Hammering Only): The bit doesn't spin. Use this with a chisel bit to scrape off tile, break concrete, or channel walls for piping.
Recommended Drilling Range: Best for drilling holes between 1/4" to 1" (6mm to 26mm) in concrete for anchors and rebar.
Core Drilling: For larger holes (like 2"–3" for PVC pipes), use a specialized core bit on low speed.
No. SDS chucks require special SDS bits with grooves on the end that lock into the tool. Standard round or hex bits will not stay in place unless you install an SDS-to-Standard Chuck Adapter.
Hammering into solid concrete requires high energy.
2.0Ah–4.0Ah Battery: Great for quick tasks or working overhead on a ladder (lighter weight).
5.0Ah–8.0Ah Battery: Highly recommended for heavy drilling, deep holes, or continuous chiseling so you don't run out of power halfway through the job.
Joules (J) measure the hitting power of each hammer blow:
1.5 J – 2.5 J: Light & versatile. Perfect for installing anchors, conduits, and light tile removal.
3.0 J – 5.0 J+: High power. Ideal for thick concrete, fast deep drilling, and heavy chiseling.
Yes, thanks to the safety clutch. If the bit hits steel rebar and stops suddenly, the safety clutch disengages the motor so the tool won't twist out of your hands or hurt your wrist.
Keep it clean: Wipe dust off the grooves at the end of the drill bit before inserting it.
Use SDS Grease: Apply a small dab of grease to the bit end before insertion to reduce friction, prevent overheating, and extend the tool's lifespan.
Yes! The standard kit includes:
1× Cordless Rotary Hammer Drill
1× Auxiliary Side Handle & Depth Gauge
Rechargeable Battery & Fast Charger
Starter SDS Bits & Storage Case
(Charge the battery, apply a little grease to your bit, slide it into the SDS chuck, and you're ready to drill!)
