What our Experts Think

• Heavy‑Duty Power & Runtime: Combines a brushless motor with the 40V Max XGT system to deliver robust performance for demanding concrete drilling and chiseling — wireless power that approaches corded capability.

• Versatile Chuck System: Quick‑change interchangeable chuck switches easily between SDS‑PLUS and 1/2″ keyless modes, expanding bit options for greater job flexibility.

• Advanced Comfort & Control: Anti‑Vibration Technology (AVT) with internal counterbalance and vibration‑absorbing handles reduces fatigue during extended use — essential for pro users.

• Smart Protection Features: Active Feedback‑Sensing Technology (AFT) shuts the tool down if a bit binds, safeguarding both the user and the tool’s internals.

• AWS Compatibility & Dust Prep: Supports Auto‑Start Wireless System (AWS) for automatic dust extractor control (accessory sold separately) and is capable of OSHA Table 1 compliant dust extraction setups.

• Pro‑Grade Build: Constant speed control and overload protection optimize performance under load, while XPT dust/water resistance boosts durability in tough environments.

Maintenance Tips

• Clean After Use: Wipe dust and debris from the tool body, vents, and interchangeable chuck to prevent buildup and help cooling and performance in heavy jobs.

• Lubricate Bit Shanks: Apply SDS‑PLUS bit grease to the chuck and bit shanks periodically to ease insertion and reduce wear on moving parts.

• Inspect Fasteners: Before operation, check the side handle, chuck, and any attachments for tightness to ensure safe handling and accurate drilling.

• Dust Extraction Care: If using with a dust extractor (sold separately), empty and clean filters regularly for consistent airflow and OSHA‑compliant dust control.

• Battery Best Practices: Charge the included 40V XGT battery before it’s fully drained and store in a cool, dry place to maximize lifespan.

• Rest Between Heavy Drills: After prolonged or high‑load drilling, power down and let the tool cool before continuing to prevent overheating.

• Authorized Service Only: For internal wear or repairs, use Makita authorized service centers and genuine parts to maintain performance and warranty compliance.
