Rotary Hammer Makita HR4501C

The Makita HR4501C rotary hammer is a corded AC-powered tool designed for heavy-duty drilling and chiselling in masonry and concrete. It is equipped with a 1350 W motor that delivers up to 280 RPM and an impact energy of 10.1 J, enabling efficient penetration and demolition tasks. The tool uses an SDS Max chuck for secure bit retention and supports drilling in concrete up to 45 mm diameter. Compact external dimensions (136 mm width, 458 mm depth, 288 mm height) and a 4 m power cord provide a balance of power and maneuverability for professional and advanced DIY applications.

Advantages

The HR4501C combines high motor power with substantial impact energy to maintain consistent performance in sustained drilling and chiselling operations. Its SDS Max chuck system ensures quick bit changes and stable bit seating during heavy-impact use. A moderate rotational speed and robust construction contribute to reliable productivity on demanding surfaces, while the compact footprint helps access tighter working areas. The 4 m cord increases reach without immediate need for extension leads.

Suitable for

• Drilling holes in reinforced concrete and masonry up to 45 mm diameter
• Light to medium demolition and chipping of concrete surfaces
• Installing anchors, bolts and rebar dowels in construction work
• Professional contractors and advanced DIY users requiring sustained impact performance

How to use

Before use, verify the power connection and inspect the bit and chuck for damage. Select an SDS Max bit suited to the material and diameter required, insert it into the chuck until it locks, and ensure the bit is secure. For drilling, position the bit perpendicular to the work surface, start the tool at low speed to create a guide, then apply steady pressure while allowing the hammer action to do the work. For chiselling, set the tool mode if available and apply controlled, even strokes. Allow occasional pauses during extended operation to prevent overheating and monitor bit wear.

Usage recommendations

Use appropriate personal protective equipment such as eye and ear protection, dust mask and gloves. For extended reach or confined workspace, consider a GFCI-protected extension lead rated for the tool's power. Regularly check and replace worn bits, and maintain ventilation when working in enclosed areas to reduce dust exposure.
