Cordless rotary hammer Bosch UNEO Maxx — compact cordless hammer drill, model UNEO Maxx

Bosch UNEO Maxx is a compact cordless rotary hammer designed for drilling and light chiselling in concrete, masonry and similar materials. As a battery-powered tool, the UNEO Maxx combines hammer action with a conventional drilling mode to cover common on-site and home renovation tasks without the need for a power cable. The tool's compact dimensions and reduced weight make it suitable for work in confined spaces and for transport between jobs.

Advantages

A combined hammer-and-drill function allows switching between impact drilling in masonry and normal drilling in wood and metal. Compact form factor and ergonomic grip reduce user fatigue during extended use. Durable construction and straightforward controls deliver reliable performance for installers and DIY users who need a versatile, portable rotary hammer.

• Drilling holes in concrete and masonry for anchors and dowels
• Light chiselling and chip removal in renovation works
• Drilling in wood and metal when hammer action is not required
• Installation tasks and fastenings in apartments, workshops and small construction sites

Key specifications

• Power source: cordless battery operation for cable-free use
• Operating modes: hammer drilling and standard drilling
• Design: compact and lightweight housing for work in tight spaces
• Chuck type: SDS or comparable quick-change system for rotary hammer bits
• Ergonomics: soft-grip handle and balanced centre of gravity for reduced fatigue

How to use

Choose the appropriate drill bit or chisel and secure it in the tool's chuck according to the manufacturer's instructions. Select the operating mode — hammer drilling for masonry or standard drilling for wood and metal — then set the required speed or torque if available. Mark the drilling position, hold the tool firmly with both hands, and apply steady pressure while drilling. For chiselling, use short controlled strokes and allow the tool to do the work rather than forcing it. After use, remove the bit, clean dust from the tool and ventilation slots, and store the battery separately if recommended by the battery manufacturer.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and dust mask when drilling in masonry or concrete. Match drill bits and chisels to the material and task, and allow the battery to cool between heavy-duty operations to maintain optimal performance and battery life.
