2. Heavy Duty SDS Plus Ground Rod Driver for Rotary Hammer Drills, Durable Steel Socket for Rod Installation
This specialized tool solves a very specific but back-breaking problem: driving long ground rods. It takes the brutal, repetitive hammering out of electrical and grounding work by letting your rotary hammer do the heavy lifting. It’s a genius attachment for electricians and serious DIYers.
Key Features That Stand Out

Pros and Cons
Pros:
- Turns a difficult, tiring job into a quick and easy one.

Customer Reviews
Customer Review: “I purchased this flat driver to use mainly with my cordless SDS+ rotary hammer for things like installing lag shields flush with concrete walls without having to also carry a hammer to set them. It is so small that it’s almost cute, but I find it can work as a light duty concrete form shaker/vibrator.”
Customer Review: “Works perfectly for its intended purpose. Drove an 8-foot ground rod in minutes instead of an hour of swinging a sledge.”
3. 17-Piece SDS Plus Carbide-Tipped Rotary Hammer Drill Bit and Chisel Set for Masonry, Brick, and Stone
If you need a full-featured set but are watching your wallet, this is your winner. It delivers the same core functionality as our top pick—a wide array of bits and chisels—at a price that’s incredibly hard to argue with. Perfect for the homeowner tackling a big project on a budget.
Key Features That Stand Out
✓ High-Quality YG8C Carbide materials for superior hardness. ✓ U-Shaped Flute Design for fast dust and chip removal. ✓ SDS Plus Shank for universal compatibility. ✓ Comprehensive set of 17 pieces for drilling and chipping tasks.
Why We Recommend It
You get serious bang for your buck. The performance punches well above its price class, handling masonry, brick, and stone with ease. It’s an ideal “disposable” set for a one-time project or a fantastic backup kit for a pro who doesn’t want to risk their premium bits on uncertain jobs.
Best For
Budget-conscious DIYers, homeowners doing occasional masonry work, or professionals looking for a reliable secondary or loaner set.
Pros and Cons
Pros:
- Unbeatable value for a 17-piece carbide-tipped set.
- Effective dust removal design keeps the hole clean.
- Widely compatible and works as advertised.
- Great for occasional use and smaller projects.
Cons:
- Typically does not include a storage case (check listing at time of purchase).
- Longevity under constant, heavy-duty professional use may be less than premium brands.
Customer Reviews
Customer Review: “Good price for the kit works great for my tool.”
Customer Review: “Exactly what I needed for a bathroom remodel. Drilled through old brick like butter. For the price, I’m very impressed.”
4. Yakamoz 1.5-13mm Quick Change Drill Chuck Adapter with SDS Plus Shank for Rotary Hammer Drill Conversion
This clever adapter is a bridge between tool worlds. It lets you use standard twist drill bits, spade bits, or even hole saws in your SDS Plus rotary hammer. It essentially turns your hammer drill into a more versatile, heavy-duty drill press for wood and metal when you don’t need the hammering action.
Key Features That Stand Out
✓ Converts your rotary hammer to accept standard drill bits. ✓ Classic Keyed 3-Jaw Chuck for a secure grip. ✓ Wide Capacity from 1.5mm to 13mm (1/16″ to 1/2″). ✓ SDS Plus Shank for quick and easy tool-free changes.
Why We Recommend It
It maximizes the utility of your tool. Instead of needing a separate cordless drill for every task, you can often just swap attachments. It’s perfect for when you need to drill a large diameter hole in a beam or metal after you’ve finished drilling into concrete.
Best For
Anyone who wants to reduce the number of tools they carry, or needs to drill large holes with their rotary hammer’s superior torque and stability.
Pros and Cons
Pros:
- Greatly increases the versatility of your SDS Plus hammer.
- Secure keyed chuck holds bits tightly.
- Inexpensive way to avoid buying a separate heavy-duty drill.
- Solid construction for its purpose.
Cons:
- Only for drilling (rotary mode), NOT for hammering. Using the hammer function will destroy the adapter and the bit.
- Adds length to the tool, which can be awkward in tight spaces.
Customer Reviews
Customer Review: “Works great on my Milwaukee drill to power my ice auger.”
Customer Review: “This adapter saved me on a job site. Needed to drill some large holes in a joist and my regular drill died. Popped this in the hammer drill (in drill-only mode!) and finished the job. Lifesaver.”
5. LEIFIDE 2-Piece Heavy Duty Ground Rod Driver Set for 5/8 and 3/4 Inch Rods for Rotary Hammers
This two-piece set is for the user who needs versatility in ground rod installation. It includes a dual-size driver and a separate flat hammer, giving you options for different rod sizes and a tool for final tamping or other light striking work. It’s a complete small kit for grounding jobs.
Key Features That Stand Out
✓ 2-Piece Set includes a driver for 5/8″ and 3/4″ rods and a flat hammer. ✓ Simple and Efficient design for fast rod installation. ✓ Satisfactory Quality forged steel with heat treatment. ✓ 10mm Hex Shank for compatibility with various rotary hammers (check your tool’s chuck type).
Why We Recommend It
The inclusion of the flat hammer is a thoughtful touch for finishing work. Having two common rod sizes covered in one driver adds convenience. The heat treatment promises good durability, making it a reliable choice for multiple projects.
Best For
Electricians or DIYers who work with both 5/8″ and 3/4″ ground rods and want a compact, dual-purpose set.
Pros and Cons
Pros:
- Covers the two most common ground rod sizes.
- Added flat hammer increases the set’s utility.
- Compact and easy to store with your other electrician’s tools.
- Good value for a two-piece specialized set.
Cons:
- Uses a hex shank, not SDS Plus. Ensure your rotary hammer has a compatible chuck (often found on combi-hammers or certain models).
- May not be as universally compatible as SDS Plus shank tools.
Customer Reviews
Customer Review: “Worked perfectly for installing my generator ground rod. The driver handled the 5/8 rod no problem, and the flat hammer was useful for other tasks.”
Customer Review: “Solid construction. Make sure your hammer drill has a chuck that accepts a 10mm hex bit, not just SDS. Once I confirmed that, it worked like a charm.”
6. 6-Piece SDS Plus Chisel Set for Rotary Hammers, Includes Point, Flat, Scaling, and Tile Removal Bits
Focused purely on demolition and material removal, this set gives you specialized chisels for different tasks. Instead of a generic flat chisel, you get tools designed for pinpoint breaking, wide scraping, and tile removal. It’s for when you need to do more than just drill holes.
Key Features That Stand Out
✓ All In One Set with Point, Flat, Scaling, and Tile Removal chisels. ✓ Premium Quality 40Cr alloy steel for high hardness and wear resistance. ✓ SDS Plus Shank for universal compatibility. ✓ Specialized shapes make each task more efficient.
Why We Recommend It
The right chisel shape makes demolition work drastically easier and less tiring. A scaling chisel removes old mortar or concrete spall far better than a flat chisel. If you’re facing a remodeling project involving tile or concrete breakup, this focused set is invaluable.
Best For
Home remodelers, tradespeople, and DIYers tackling demolition, tile removal, concrete repair, or brickwork.
Pros and Cons
Pros:
- Specialized tools for specific demolition tasks increase efficiency.
- High-strength steel holds up to heavy pounding.
- Good selection for most common chiseling needs.
- No-nonsense, practical set without extra drill bits you might not need.
Cons:
- Does not include any drill bits.
- May not include a storage case, so you’ll need to provide your own organization.
Customer Reviews
Customer Review: “These came as advertised and worked great. I had to remove about 20 cemented in fence posts, and these chisel bits broke up the cement nicely so I could pull out chunks instead of trying to dig up 80-160 lbs blocks of cement.”
Customer Review: “The tile chisel made short work of my old kitchen floor. The point chisel was perfect for starting breaks in a concrete slab. Great set for the money.”
7. ZELCAN 6-Piece SDS Plus Chisel Set, High-Strength 40Cr Steel Masonry Tools for Concrete and Tile Removal
This is another excellent, focused chisel set built for punishment. It emphasizes a secure, non-slip connection in the tool chuck, which is critical when you’re applying serious force. The inclusion of a grooving chisel adds another useful niche function for channeling or cutting lines.
Key Features That Stand Out
✓ All-In-One Kit with tile, grooving, scraping, flat, and point chisels. ✓ SDS Plus Shanks for universal compatibility. ✓ Non-Slip Connection design for secure grip in the hammer drill. ✓ High-Strength 40Cr Steel construction.
Why We Recommend It
It’s a well-rounded demolition set from a brand with a good reputation. The attention to the shank design to prevent slipping shows they’ve thought about real-world use. If you’re between the #6 set and this one, you can’t go wrong with either; it often comes down to price and the specific chisel shapes included.
Best For
Contractors and skilled DIYers who need reliable, tough chisels for frequent concrete work, tile removal, and light demolition.
Pros and Cons
Pros:
- Very durable and long-lasting under heavy use.
- Grooving chisel is a unique and useful addition for cutting lines.
- Secure shank design prevents spin-out in the chuck.
- Trusted brand with positive user feedback over time.
Cons:
- Like other chisel-only sets, you’ll need to buy drill bits separately.
- Can be more expensive than some no-name brands, reflecting its higher quality.
Customer Reviews
Customer Review: “Used these chisels to break up tile intended in cement. Work well. Sturdy and well priced”
Customer Review: “I’ve worn these out using them and they have held up great, still use them.”
8. Greywolf 3-Inch SDS Plus Wide Cranked Floor Scraper Chisel, Heavy Duty Alloy Steel Tile Removal Bit
This is a specialist’s specialist tool. The wide, cranked (bent) design is engineered for one primary task: efficiently scraping up flooring materials like tile, vinyl, or epoxy coatings from large, flat surfaces. It turns a grueling job into a much faster one.
Key Features That Stand Out
✓ 20° Bent Angle Design for comfortable, ergonomic use on floors. ✓ 40CrMo Alloy Steel with proprietary heat treatment for maximum toughness. ✓ 3-Inch Wide Sharp Blade for covering large areas quickly. ✓ Designed specifically for floor scraping and wide-area material removal.
Why We Recommend It
If you have a floor to strip, nothing else will compare. The width removes material in a big swath, and the bent angle lets you work without straining your back as much. It’s a single-purpose tool that excels so much at its job that it’s worth buying even if you only use it once.
Best For
Flooring contractors, remodelers removing old tile or glued-down flooring, and anyone facing a large-scale floor preparation job.
Pros and Cons
Pros:
- Extremely efficient for its intended purpose—drastically speeds up floor removal.
- Ergonomic design reduces user fatigue.
- Very wide blade minimizes the number of passes needed.
- Extremely robust construction for a punishing application.
Cons:
- Very specific use case; not a general-purpose chisel.
- Requires a powerful rotary hammer to drive it effectively across a large floor.
Customer Reviews
Customer Review: “Used it to break up hard dirt to tunnel under my house to fix the plumbing. Works great.”
Customer Review: “it was the wrong tool for the job i’m sure it will be great for the project that it’s meant for.”
Complete Buying Guide for Hammer Drill Attachments
Essential Factors We Consider
Choosing the right attachment isn’t just about price. First, know your tool’s shank type—SDS Plus is the most common for DIY and prosumer rotary hammers. Using the wrong shank is impossible and dangerous. Next, consider the material you’ll be working on. Carbide tips are essential for concrete and masonry, while high-alloy steel like 40Cr or 42CrMo is key for chisels. Also, think about the task: drilling needs flute designs for dust removal, while demolition needs the right chisel shape (point, flat, scaling). Finally, don’t forget about the basics of the difference between a hammer drill and a regular drill to ensure you’re using the right base tool for the job.
Budget Planning
Your budget should match your usage. For occasional DIY tasks, a budget-friendly combo set like our #3 pick offers tremendous value. If you use these tools professionally, investing in individual, high-quality attachments or a premium set (#1) will save money in the long run through better performance and longevity. Remember, a specialized tool like a ground rod driver (#2 or #5) or floor scraper (#8) can be worth its weight in gold for that specific job, even if it’s a single-purpose purchase.
Final Thoughts
The best hammer drill attachment is the one that safely and efficiently helps you finish your project. Start with a versatile set to cover bases, then add specialized tools as your skills and project list grow. Always prioritize secure compatibility and material quality over flashy piece counts. With the right attachments, your rotary hammer becomes one of the most useful tools in your shed.
Frequently Asked Questions
Q: Can I use SDS Plus bits in a regular drill?
A: No, you cannot. SDS Plus bits are designed for the specific chuck and hammering action of an SDS Plus rotary hammer. A regular drill chuck cannot hold them, and using them without the hammer function would be ineffective. To understand the mechanisms at play, check out our guide on the difference between a drill and a hammer drill.
Q: What’s the difference between an SDS Plus and an SDS Max shank?
A: SDS Max is a larger, heavier-duty shank system designed for bigger, more powerful rotary hammers and demolition hammers. SDS Plus is for light to medium-duty tools. They are not interchangeable. Always match the attachment shank to your tool’s specification.
Q: How do I know when my hammer drill bit is dull and needs replacing?
A: Signs include drastically slower drilling speed, excessive heat and smoking, the bit spinning without making progress, or a rounded-over or chipped carbide tip. A dull bit strains your tool and is unsafe. It’s better to replace it.
Q: Can I use hammer drill attachments for chiseling in an impact driver?
A: Absolutely not. Impact drivers and rotary hammers are completely different tools. An impact driver delivers rotational impacts for driving screws, while a rotary hammer delivers linear, hammer-like blows for drilling and chipping. The chucks and forces are incompatible and attempting to use them together is dangerous.
Q: How do I safely change an SDS Plus bit or chisel?
A> Always disconnect the tool from power (or remove the battery). Pull the chuck sleeve back, insert the new bit until it clicks into place, then release the sleeve. Give the bit a gentle tug to ensure it’s locked in before operating.
