The tool's compact and lightweight construction improves maneuverability in confined spaces and during overhead work. Controls and ergonomics are designed for straightforward operation and steady control during drilling and chiseling.

Suitable for

• Drilling holes for anchors and fasteners in masonry and concrete
• Light chiseling tasks such as removing tiles or mortar joints
• Drilling in wood and metal where impact function is not required
• On-site repair and installation work requiring a cordless solution
• Work in confined spaces or overhead applications where low weight is beneficial

Key specifications

• Impact energy: 2.4 joules
• Power system: brushless motor for increased efficiency
• Battery: two lithium-ion batteries, 5.0 Ah each for extended runtime
• Operation modes: drilling and hammer drilling with chiseling capability
• Design: compact and lightweight for improved handling

How to use

Before use, ensure batteries are fully charged and correctly inserted. Select the appropriate drill bit or chisel and secure it according to the tool’s chuck or SDS interface. For drilling in masonry or concrete, use the hammer-drill mode and apply steady pressure without forcing the tool; allow the hammering action to do the work. For wood or metal, switch to standard drilling mode if available. Use the auxiliary handle for better control and maintain a firm, balanced stance. After completing work, remove the battery before changing accessories or performing maintenance.

Recommendations

Wear appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling or chiseling. Use drill bits and chisels rated for masonry or concrete when engaging hammer function, and follow manufacturer guidance for charging and storing batteries to prolong their service life.
