Key Features & Benefits
- 8.0 J Impact Energy — delivers genuine corded-class hammer performance for drilling large anchor holes, core penetrations, and fixings up to 40 mm in reinforced concrete.
- 36V (18V×2) Dual-Battery Power — runs on two standard 18V LXT batteries simultaneously, providing corded-equivalent power without needing a separate 36V battery platform.
- Active Feedback-Sensing Technology (AFT) — electronically shuts down the motor if the bit jams in reinforcement, preventing dangerous kickback and wrist injury.
- Anti-Vibration Technology (AVT) — brings vibration down to 5.0 m/s², significantly less than corded hammers in this class, extending safe working time and reducing fatigue.
- AWS Compatible — wirelessly starts a compatible Makita dust extractor when you pull the trigger, maintaining silica dust compliance without a separate switch.
- XPT Protection — improved sealing protects the motor and electronics from dust and moisture during outdoor and demolition work.
When to Use This Rotary Hammer
The DHR400ZKN is the cordless alternative to a corded SDS Max hammer for heavy concrete work. Use it for drilling large anchor holes (M16–M24), core drilling penetrations for pipe and conduit, and light chiselling tasks like concrete removal and channel chasing. The 8.0 J output matches many corded SDS Max hammers while the dual 18V battery system uses the same packs as your other LXT tools — no separate charger or battery platform needed. The AFT and AVT safety systems make it safer and more comfortable than corded equivalents. For light concrete drilling up to 24 mm, a standard SDS Plus hammer is sufficient; the DHR400ZKN is for when you need the 40 mm capacity and 8.0 J power of the SDS Max class.
