The Stanley STHM5KH 5Kg Demolition/Percussion Hammer is a powerful corded hex chipping hammer designed for professional light to medium demolition, chiseling, chipping and surface-preparation applications. Stanley specifies the tool for working on concrete, brick and masonry, making it suitable for construction, renovation and maintenance jobs.
Powered by a 1010W motor, the STHM5KH delivers an 8.5J impact energy at an impact rate of approximately 2900 BPM. This combination provides strong impact performance for breaking, removing and shaping compatible masonry and concrete materials. The 17mm Hex tool holder is designed for compatible chisels and accessories.
The hammer incorporates an anti-vibration spring handle and a rubber-coated grip, helping improve operator comfort and reduce fatigue during extended chipping operations. Its 360° adjustable side handle provides additional control and allows the user to select a comfortable working position.
The large hammer mechanism is engineered for durability and concrete-breaking performance, while the ON/OFF rocker switch enables convenient continuous operation. The tool also features accessible carbon-brush covers and a modular construction intended to simplify servicing.
