How it helps you work smarter
Hydraulic impact technology delivers a controlled, powerful torque punch that minimizes bit cam-out and reduces operator fatigue. The brushless motor provides efficient power delivery, so you get more productive cycles per battery charge. With a 1/4 in. hex drive, you can quickly swap in a wide range of impact-rated bits for wood, metal, or composite fasteners, making it ideal for deck projects, cabinet installation, automotive work, and HVAC installations where space is at a premium.
Ideal for who and where you’ll use it
- Professional tradespeople (carpenters, electricians, plumbers, HVAC technicians) who need reliable fastening in tight environments
- Serious DIYers tackling projects with dense materials or long fasteners where a traditional screwdriver or drill struggles
- Photographers or technicians working overhead or in confined areas where a compact tool is a must
Practical tips to get the most from this tool
- Pair with Milwaukee 18V Li‑ion batteries for optimal runtime and quick charge times on site
- Use the LED work light to illuminate dark work areas and prevent cross-threading or misalignment
- Take advantage of the high IPM and torque for heavy-duty fasteners, then switch to lower speeds for delicate work to avoid stripping
- Because this is a tool-only model, ensure you have the appropriate bits and a battery/charger compatible with the M18 system
Why choose Milwaukee FUEL for your toolkit
Milwaukee’s FUEL line is designed for durability and real-world performance. The combination of a brushless motor and hydraulic impacts means you’ll experience efficient power delivery, reduced motor heat, and longer tool life compared with standard brushed drivers. The 5-year limited warranty provides peace of mind for daily use on busy job sites, so you can rely on this tool when it matters most.
