Hammer Drill Makita HR004GM201

The Makita HR004GM201 is a cordless hammer drill with SDS-plus technology designed for professional drilling and chiseling. Powered by a 40V battery system and rated for an impact energy of 2.9 Joules, this rotary hammer combines the mobility of cordless operation with the performance required for medium to heavy-duty construction and renovation tasks. The tool is supplied with two batteries and a charger to ensure extended runtime on site.

Advantages

This hammer drill provides reliable percussion performance with an impact energy of 2.9 Joules while maintaining the convenience of a cordless design. SDS-plus bit retention enables fast accessory changes and secure seating for drilling and chiseling applications. Operating on a 40V battery platform gives longer run times and higher torque compared with lower-voltage cordless models. Supplied batteries and charger reduce downtime, and the tool’s balanced construction improves handling during extended use.

Suitable for

• Drilling into concrete, brick and masonry with SDS-plus bits
• Chiseling and light demolition work
• Installation tasks such as anchor and anchor bolt preparation
• Professional renovation and construction sites requiring cordless mobility

Key specifications

• Drive type: SDS-plus rotary hammer mechanism
• Impact energy: 2.9 Joules
• Power source: 40V battery system (two batteries included)
• Modes: drilling, hammer drilling and chiseling (selectable)
• Accessory compatibility: SDS-plus bits and chisels
• Supplied with charger and two rechargeable batteries for extended runtime

How to use

Select the appropriate mode for the task—hammer drilling for concrete and masonry, or chiseling for removal work—and install an SDS-plus bit or chisel by inserting it into the tool’s chuck until it locks. Ensure batteries are fully charged before starting intensive work. Hold the drill with both hands, align the bit perpendicular to the work surface, and apply steady pressure; allow the tool’s percussion action to do the work rather than forcing the bit. For repeated or continuous operations, rotate the work schedule to allow batteries to cool and recharge as needed.

Usage recommendations

Use high-quality SDS-plus bits sized for the material and task, wear appropriate personal protective equipment (eye, ear and respiratory protection), and follow Makita battery care guidelines to maintain optimal performance and battery life. For heavy chiseling, use the correct chisel shape and avoid prolonged continuous heavy load to prevent overheating.
