Buying Guide: Key Purchase Considerations
- Drilling vs. hammer power: For routine wood and metal drilling, a hammer drill with a robust motor and good chuck grip is sufficient. For concrete or masonry, SDS or rotary hammer options with higher impact energy (measured in joules) deliver faster penetration.
- Motor type: Brushless motors provide longer runtime and durability compared with brushed motors. They are common on newer models and generally preferable for ongoing use.
- Battery platform: Choose a tool that aligns with your existing batteries to protect your investment. 20V MAX and 21V platforms offer broad compatibility with many accessories and tools.
- Weight and balance: Lighter, well-balanced tools reduce user fatigue, especially on long jobs. Consider compact designs for tight spaces.
- Chuck type and retention: A metal 1/2-inch ratcheting chuck offers secure bit retention under heavy loads. For SDS tools, the chuck system is designed for quick bit changes and compatibility with masonry bits.
- Vibration control: Tools with vibration-damping features reduce fatigue and improve control during concrete drilling.
- Accessories included: Kits with extra batteries and chargers can improve uptime on job sites, while bare tools are lighter but require separate battery purchases.
- Durability and warranty: Look for tools with robust housings, metal components for downtimes, and favorable warranty terms for professional use.
