Martelo perfurador Makita HR2811FT – 800 W, 2,9 J energia de impacto, 1100 rpm, 4500 bpm

Makita HR2811FT is a corded SDS-Plus rotary hammer engineered for light to medium-duty drilling and chiselling in concrete, masonry and brick. The tool features an 800 W motor delivering up to 1100 RPM no-load speed and a maximum impact energy of 2.9 J with 4500 bpm, providing a balance of drilling speed and percussive force for common construction and renovation tasks. The compact length of 345 mm and a net weight of approximately 3.3 kg make the unit easier to handle on-site, while an ergonomic housing and integrated LED job light support controlled operation in confined or dimly lit areas.

Advantages

Double insulation increases user safety during daily operation without requiring a separate grounding connection. Variable speed control and a reversing function allow precise start-up and controlled withdrawal of bits. The built-in torque limiter protects the operator and tool by stopping rotation if the bit binds against reinforcement, reducing kickback. Improved dust collection helps maintain visibility of the work area and prolongs bit life. The LED job light enhances accuracy when working in low-light conditions.

Suitable for

• Drilling holes in concrete and masonry for anchor bolts and fixings
• Chiselling small areas for tile removal, plaster or mortar removal
• Drilling in brick and block materials for through-holes and service openings
• Light demolition and renovation tasks requiring SDS-Plus accessories

How to use

Select an appropriate SDS-Plus bit for the material and secure it into the chuck until it locks. Choose the required mode (drilling, hammer drilling or chiselling) and set the variable speed according to bit diameter and material hardness. When drilling through reinforced concrete or when the bit binds, the torque limiter and reversing function help disengage the bit safely. Use the auxiliary handle to maintain control and the LED job light to improve visibility at the point of contact. Always allow the tool to reach operating speed before applying heavy pressure and withdraw the bit occasionally to clear debris.

Recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. Match drill bit type and size to the task and avoid applying excessive axial force—let the hammer action do the work. For extended drilling sessions, allow periodic cooling breaks to prevent motor overheating and maintain the dust collection system for optimal performance.
