Rotary Hammer Makita HR4501C

The Makita HR4501C rotary hammer combines a high-power 1350 W motor with SDS Max bit compatibility to deliver reliable percussion drilling and chiselling performance. Designed for work on concrete and masonry, it provides an impact energy of 10.1 J and a maximum no-load speed of 280 RPM. The tool is mains powered with a 4 m cord and compact physical dimensions (136 mm width, 458 mm depth, 288 mm height) for improved handling on confined jobsites and overhead tasks.

Advantages

The HR4501C offers robust drilling force through its 1350 W motor together with a 10.1 J impact energy, enabling effective penetration in concrete and dense masonry. Using an SDS Max chuck ensures fast, tool-free bit changes and compatibility with a wide range of heavy-duty drill and chisel bits. Its compact footprint and manageable weight distribution make it easier to control during long periods of use, while the 4 m power cord gives flexibility without immediate need for an extension.

Suitable for

• Drilling large-diameter holes in concrete and reinforced concrete
• Chiselling, demolition of small sections of masonry and tile removal
• Anchoring and installing heavy fixtures in structural walls
• Professional construction, renovation and mechanical installation works

How to use

Select an SDS Max bit appropriate for the task and secure it into the chuck according to the tool’s insertion method. Set the unit to the required mode (rotary with percussion for drilling, or percussion-only for chiselling) and position the bit on the marked drilling point. Start the tool at low speed to establish the hole and then apply steady, moderate pressure while allowing the hammer action to do the work; avoid forcing the tool. For chiselling, use controlled passes and reposition the tool as necessary to remove material evenly.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and dust mask when drilling or chiselling concrete. Verify bit condition before use and allow the motor to cool during extended continuous operation. For prolonged cable reach, use a site-rated extension with suitable current capacity; inspect the cord for damage prior to use.
