Complete Buying Guide for Hammer Drill Post Driver Attachment
Essential Factors We Consider
When choosing a hammer drill post driver attachment, the shank type is critical. SDS Plus fits most standard rotary hammers, while SDS Max is for heavier tools.

If you’re unsure about your tool, check out our guide on the difference between a hammer drill and regular drill to ensure you have the right power source.
Budget Planning
Prices range from budget-friendly to professional-grade. For occasional use, a cheaper SDS Plus model works fine. For frequent or heavy-duty jobs, invest in a durable SDS Max attachment. Remember, a good attachment can save money on labor and tool replacement in the long run.
Final Thoughts

Frequently Asked Questions
Q: Can I use a hammer drill post driver attachment with any hammer drill?
A: No, you must match the shank type. SDS Plus attachments only fit SDS Plus hammer drills, and SDS Max fit SDS Max drills. Using the wrong type can damage both the attachment and your tool. Always check compatibility first.
Q: How do I prevent damaging the posts when using these attachments?
A: Some paint chipping is common due to impact, but you can minimize it by ensuring the post is aligned and using the correct head size. For general tool tips, our guide on how to use a drill for screws into a wall covers proper technique and alignment.
Q: Are these attachments suitable for driving ground rods for electrical work?
A: Yes, many are designed specifically for ground rods. Look for models with adapter bits for different sizes, and ensure your hammer drill has enough power. They’re much faster and safer than manual methods for electrical grounding.
Q: What’s the difference between SDS Plus and SDS Max for these attachments?
A: SDS Max is larger and handles more power, ideal for heavy-duty jobs. SDS Plus is for standard rotary hammers. Choose based on your drill’s capability; SDS Max attachments won’t fit SDS Plus drills, and vice versa.
Q: Can I use these attachments on concrete or only soil?
A: Primarily for soil, clay, or softer ground. They’re not designed for driving into hard concrete—use masonry bits for that. For hard surfaces, ensure the attachment is used as intended to avoid damage.
