1 Inch Rotary Hammer Drill, 3-in-1 Corded Variable Speed Electric Hammer for Concrete Masonry Wood Steel

Upgrade your tool kit with this 3-in-1 SDS-Plus Rotary Hammer Drill — the reliable, high-performance power tool for professional contractors, home renovators, and DIY enthusiasts. Perfectly adapted to 120V 60Hz US standard outlets, it handles all your concrete drilling, masonry chiseling, and daily drilling jobs with ease.Hard-Hitting Power for Demanding JobsEngineered with an 850W high-efficiency pure copper motor, this rotary hammer delivers a robust 3.2J (2.36 ft-lbs) of impact energy, paired with 0-1150 RPM variable no-load speed and 0-5100 BPM impact frequency. It achieves fast, precise drilling with maximum capacities: 26mm (1 Inch) for concrete, 30mm for wood, and 13mm for steel. The fully enclosed heat dissipation system ensures stable performance during long-time continuous work, greatly extending the tool's service life.3 Modes for Ultimate VersatilityReplace multiple tools with one all-in-one machine. The 3-function selector lets you switch smoothly between 3 working modes: rotation-only for wood/steel drilling, rotary hammer for concrete/masonry drilling, and hammer-only for chipping, demolition, and grooving. The 360° vario-lock positioning system rotates and locks the chisel into your optimal working angle, maximizing efficiency for every job.Safe & Comfortable All-Day OperationThe ergonomic D-handle with non-slip soft rubber grip effectively absorbs vibration, minimizing hand fatigue during long hours of work, and delivers optimal control for overhead, downward, and tight-space drilling. The built-in integral safety clutch automatically disengages torque transmission if the bit binds up, effectively preventing kickback to protect your safety. The double-insulated structure fully complies with UL US electrical safety standards, providing reliable protection for every operation.Core Product Specifications (US Standard)Rated Voltage: 120V | Rated Frequency: 60Hz (US Standard)Rated Input Power: 850WNo-Load Speed: 0-1150 RPMImpact Frequency: 0-5100 BPMSingle Impact Energy: 3.2JMax Drilling Diameter: 26mm (1 Inch) Concrete | 30mm Wood | 13mm SteelWorking Modes: Rotation Only / Rotary Hammer / Hammer OnlyInsulation Grade: Double Insulation (UL Compliant)Item Weight: 5kg (11 lbs)Chuck Type: SDS-Plus Round ShankFull Package List (Ready to Use Out of the Box)1 x Rotary Hammer Main Unit | 1 x 360° Rotatable Auxiliary Handle | 1 x Depth Gauge | 1 x Precision Steel Drill Chuck | 1 x Chuck Key | 1 x 14*250mm Pointed Chisel | 1 x 14*250mm Flat Chisel | 3pcs Masonry Drill Bits (6/8/10*150mm) | 1 x Heavy-Duty Carrying Case
