DEWALT 20V MAX* XR Brushless Cordless 1/4 in. Quiet Hydraulic Impact Driver + FREE 20V MAX* 5Ah Battery DCB205
Model Number: DEWDCF870B
ADVANCED HYDRAULIC PULSE FOR HIGH-SPEED STEALTH FASTENING
The DCF870B represents a significant mechanical shift in impact technology, utilizing an oil-impulse hydraulic mechanism to replace the traditional metal-on-metal hammer and anvil strike. This fluid-drive system doesn't just dampen noise by up to 57%—it smooths out the torque delivery, resulting in less vibration and more consistent fastener engagement. For professionals working in occupied hospitals, schools, or high-end residential interiors, this tool maintains a professional atmosphere without sacrificing the driving speed required for high-volume production. Its ultra-compact 4-inch head length ensures that torque is delivered exactly where it's needed, even in the tightest cabinet corners or framing clusters.
- / 57% Quieter Operation: Advanced fluid-drive technology minimizes noise disruption in sensitive environments while maintaining professional-grade speed.
- / Ultra-Compact 4-Inch Profile: Engineered for maximum accessibility in confined spaces where standard impact drivers cannot reach.
- / 9-LED Work Light Ring: Delivers up to 6X brightness with a dedicated 20-minute stay-on mode for superior visibility in dark enclosures.
- / XR Brushless Motor: Optimizes power delivery and thermal management for extended runtime and long-term tool durability.
- / Sustained Hydraulic Torque: Delivers 500 in-lbs of torque and 4,200 IPM for fast, efficient driving of large screws and lags.

MAXIMIZING DUTY CYCLES WITH ADVANCED XR LITHIUM-ION ARCHITECTURE
Professional tool users understand that runtime isn't just about convenience; it's about minimizing downtime between charges to maintain a high workflow cadence. The DCB205 5.0Ah battery pack utilizes high-quality lithium-ion cells that provide a significant 60% increase in capacity compared to standard packs, without a substantial increase in weight or footprint. This balance of power density and ergonomics is critical for high-draw applications like circular saws or SDS Plus rotary hammers where sustained torque is required. The integrated 3-LED fuel gauge allows for precise power management, ensuring you never climb a ladder with a near-depleted pack. Engineered with no memory effect and virtually no self-discharge, these cells maintain their peak performance through hundreds of charge cycles, providing a superior return on investment for any professional fleet.
- / Premium 5.0Ah capacity provides up to 60% more runtime than standard 20V MAX* battery packs.
- / Integrated 3-LED Fuel Gauge system allows for immediate feedback on the state of charge.
- / Lightweight 1.4 lb design offers maximum runtime while minimizing user fatigue during overhead use.
- / No memory effect and virtually no self-discharge ensures the tool is ready for work even after storage.
- / Fully compatible with the entire DEWALT 20V MAX* line of tools and chargers.
