Milwaukee 5446-21 SDS-Max Demolition Hammer

The Milwaukee SDS-Max Demolition Hammer is designed for demanding concrete and masonry removal tasks where controlled impact power matters. For contractors, renovation professionals, and construction crews, this corded tool offers a practical solution for breaking up hard materials during suitable demolition work. Before ordering, verify the model number on your listing, because Milwaukee’s official product information identifies the related 5446-21 model.

Milwaukee SDS-Max Demolition Hammer Features

The 5446-21 model uses a 14-amp motor rated at 1,300 maximum watts out. Its heavy-duty crank piston mechanism delivers 8.8 ft-lbs of impact energy, helping the hammer tackle demanding concrete-chipping applications. This power makes it suitable for selected renovation, remodeling, and construction jobs that require a dedicated demolition tool.

The SDS-Max tool holder accepts compatible SDS-Max chisels and accessories. Choose the correct chisel for the material and task, and inspect the accessory before installation. Always disconnect the tool from its power source before changing accessories or making adjustments.

Two-Speed Impact Control

The two-speed impact mode offers settings of 2,200 and 2,840 blows per minute. The lower setting can suit lighter materials, while the higher setting supports more demanding concrete demolition. Selecting the appropriate mode helps you match the tool’s impact rate to the application rather than using maximum output for every task.

Constant Power Technology helps maintain performance under load. A mechanical clutch adds protection when a bit binds, while the variable-position chisel stop locks the chisel into 12 positions. These features support control and flexibility when working across different demolition angles.

Anti-Vibration Design and Handling

Milwaukee’s Anti-Vibration System helps reduce vibration transmitted to the operator during use. The side D-handle provides a secure gripping position and helps users control the tool during chiseling. The design is intended for demanding work, but operators should still follow recommended work practices and take appropriate breaks.

The 5446-21 model is a corded 120V tool, not a cordless M18 battery-powered hammer. Its power cord provides continuous electrical power when connected to a suitable supply. Check local voltage requirements and use an appropriate grounded outlet and extension cord when permitted by the operator’s manual.

For confirmed specifications, review the official Milwaukee SDS-Max demolition hammer page. Read the official operator’s manual for operating instructions, compatible accessories, and safety warnings. You can also consult OSHA’s construction resources for general workplace safety guidance.

Suitable Applications and Safe Operation

This type of demolition hammer may suit construction crews, concrete repair professionals, and renovation contractors removing appropriate sections of concrete or masonry. Confirm that the task does not involve structural elements, concealed utilities, or hazardous materials without the necessary assessment and precautions.

Wear suitable eye, hearing, respiratory, and hand protection as required by the task. Secure the work area, control dust, and keep bystanders clear of flying debris. Never force the chisel, operate damaged equipment, or ignore unusual vibration or overheating.
