Quick Answer
DeWalt offers cordless hammer drills in two main types: SDS Plus models for masonry and standard 1/2-inch models for versatile drilling in wood, metal, and occasional concrete. Choose based on your primary material and need for dedicated impact drilling versus general use.
Main Explanation
1. Brushless Motors & Anti-Rotation
Current DeWALT cordless hammer drills use brushless motors for improved efficiency and battery life. Some models have anti-rotation systems that stop the drill if it binds, enhancing safety.
2. Two Main Form Factors
- SDS Plus Hammer Drills – Designed for masonry drilling. Example: The DCH172BWB225-2C is an ultra-compact 5/8-inch SDS Plus model from the ATOMIC 20V MAX line. It comes with a 5 Ah and 2 Ah battery, suitable for tight spaces.
- Standard 1/2-inch Hammer Drills – More versatile. The DCD1007B is a 20V MAX XR brushless 3-speed hammer drill with 2,100 in-lbs of torque. Another kit, the 20V MAX XR Brushless 1/2-inch Hammer Drill, is often around $299 (was $349).
3. Power & Battery Options
DeWALT hammer drills run on the 20V MAX platform. Kits include batteries (e.g., DCH172BWB225-2C includes 5 Ah and 2 Ah packs ), while tool-only options (like DCD1007B ) save cost if you have existing batteries. The XR line offers higher runtime and power.
Practical Takeaways
- Identify your primary material. For concrete or brick, choose an SDS Plus model like the DCH172BWB225-2C. For wood and metal, a 1/2-inch keyless hammer drill (e.g., DCD1007B ) offers more versatility.
- Select chuck type. SDS Plus for frequent masonry; keyless for general use.
- Choose kit or tool only. If you own 20V MAX batteries, pick tool-only. Otherwise, a kit (like the 20V MAX XR Kit or ATOMIC bundle ) provides everything.
- Check torque. For heavy-duty drilling, look for at least 2,000 in-lbs, as in the DCD1007B.
- Compare prices. The ATOMIC SDS model and XR kit differ in cost; typical XR kit price is ~$299.
