Cordless Impact Driver Makita DFR550Z 18V — 4000 RPM, 12/7 N·m, 2.1 kg, Black/Green

The Makita DFR550Z is a compact 18V cordless power screwdriver designed for fast fastening and versatile use. With a maximum idle speed of 4000 RPM and selectable torque for soft and hard applications, it balances speed and control for a variety of screwdriving tasks. The tool’s compact footprint (80 mm width, 424 mm depth, 238 mm height) and 2.1 kg weight support comfortable handling during repetitive work, while the black and green housing reflects Makita’s recognizable design.

Advantages

The high no-load speed of up to 4000 RPM enables rapid screw insertion when working with thin materials or self-drilling screws, while the dual torque settings—12 N·m for hard applications and 7 N·m for soft applications—provide precise control to avoid overdriving. Battery power eliminates the need for a power cord and improves mobility on site. The tool’s compact dimensions and balanced weight make it suitable for overhead and confined-space work, reducing operator fatigue during extended use.

How to use

Install a compatible 18V Makita Lithium-Ion battery and select the appropriate torque setting for the material and screw type. Fit the correct screwdriver bit in the chuck, position the tip on the screw head, and apply steady pressure while operating the trigger. For repetitive screwdriving, allow the tool to reach operating speed before contact and release the trigger promptly when the screw is seated to prevent overdriving. Follow standard safety procedures, wear eye protection, and ensure the battery is charged and correctly inserted before use.

Usage recommendations

For best results, match the torque setting to the material: use the higher torque for dense timbers and harder substrates, and the lower torque for softwoods or thin sheet materials. Keep screwdriver bits in good condition to maintain efficient transfer of power and reduce cam-out. Regularly charge and store batteries according to the manufacturer’s instructions to preserve battery life and performance.
