Frequently Asked Questions
Can I use the same batteries for both tools?
Yes, both tools are compatible with Milwaukee’s M18 battery platform, so batteries are interchangeable.
Is the impact driver suitable for drilling holes?
While primarily designed for driving fasteners, the impact driver can drill into dense materials but is less ideal for precise drilling compared to a dedicated drill.
How does the safety feature AutoStop Control work?
AutoStop Control automatically stops the impact mechanism when the fastener is fully driven, reducing overdriving and improving safety.
Are batteries included with these tools?
No, batteries and chargers are sold separately for both models, allowing you to choose based on your needs.
Choosing the Right Tool for Your Projects
Ultimately, both Milwaukee tools are excellent in their domains. The hammer drill is perfect for versatile drilling tasks, especially in tight or overhead spaces, while the impact driver is unmatched for fast, high-torque fastening. Your choice depends on whether you prioritize drilling or driving fasteners, but both will serve well as part of a Milwaukee M18 toolkit.
