RYOBI’s 1/4″ impact driver provides up to 1800 in-lbs of torque and up to 3400 IPM for fast driving. Its 1/4″ quick-connect chuck allows quick bit changes, which is convenient for quick projects, drips into wood, metal, and plastic materials. The tool is part of the One+ system, offering broad battery compatibility across many DIY tasks.
DEWALT DCF860B 1/4″ Impact Driver

DEWALT’s DCF860B claims the highest torque in its class, with up to 66% more torque and 63% faster driving in some tasks. It features a variable speed trigger and a three-speed mode to tailor the driver for different materials and screw types, along with a precise performance profile for demanding fastening jobs.
Buying Guide: Key Purchase Considerations
- Torque and speed: Look for models offering 1,800–1,825 in-lbs torque with versatile speed ranges to handle large screws and fasteners efficiently.
- Motor type: Brushless motors typically deliver more power and longer life with better efficiency than brushed options.
- Drive system and control: A variable speed trigger and multiple speed settings help you adapt to delicate screws and dense materials.
- Build and ergonomics: Compact, balanced designs reduce fatigue on prolonged use. Low-vibration models improve comfort on long jobs.
- Portability: Bare-tool options save weight when you already own a compatible battery platform; tool-only purchases require battery compatibility considerations.
- Noise and workspace: Hydraulic or quieter models may be preferable for indoor projects or spaces with noise restrictions.
- Accessories and compatibility: Consider bit sets, magnetic bit holders, LED lighting, and availability of fast-changing chucks when evaluating value.
- System compatibility: If you already use a brand’s platform (DEWALT, Milwaukee, Ryobi, etc.), staying within the ecosystem can simplify battery management and spare parts.
When selecting a 1/4″ impact driver, weigh the trade-offs between torque, weight, and control. For high-torque needs in tight spaces, brushless models with robust control features and compact forms tend to perform best. Quiet operation can be a deciding factor for interior work, while tool-only options may suit long-term project planning for those already invested in a specific battery ecosystem.
