Have You Ever Asked: "Do I Really Need a Rotary Hammer, or is My Drill Good Enough?"
You’re staring at a tough job. Maybe it’s a concrete wall you need to mount a TV on, an old tile floor you need to rip up, or a brick fireplace that won't give an inch. You’ve got your drill, but a nagging thought creeps in: "Is this the right tool?" You're paralyzed by the fear of burning out your motor, making a mess, or just wasting hours getting nowhere. You’ve heard the terms "impact drill," "hammer drill," and "rotary hammer," and the confusion is common. It's a topic we cover in depth in our complete guide to drills and drivers, but today we're focused on the heavy hitters.
At a Glance: The 3 "Hammering" Tools Defined
- Impact Drill (or Hammer Drill): Your versatile all-rounder. It drills holes and adds a rapid, vibrating "tapping" action for masonry.
- Rotary Hammer: The concrete specialist. It uses a piston to deliver a powerful "hammering" blow for drilling into solid concrete and light chipping.
- Impact Driver: A specialist for driving screws. It uses rotational impacts, not forward hammering.
The Real Difference Explained: The Technology Inside
The core difference between these tools isn't size; it's the technology. It’s how they deliver the force.

What Does SDS Mean? And Why Does it Matter for Concrete?
You'll hear "SDS Drill" used by pros. SDS is a type of chuck—the part that holds the bit. It stands for "Slotted Drive System." Unlike a regular drill chuck you tighten, an SDS chuck has special grooves that the bit locks into. This transfers way more power without slipping, which is why a true rotary hammer will always have an SDS chuck.
Choosing Your IDEAL Impact Drill: The Versatile All-Rounders
An impact drill is your go-to, versatile workhorse. It drills into wood, metal, and plastic, and its hammering function makes quick work of brick, mortar, and concrete block. If you can only have one drill from our professional corded lineup for a wide range of jobs, this is it. Here's how our IDEAL models compare.

How to Drill a Perfect Hole in Concrete: A Step-by-Step Guide
Drill perfect holes in concrete with this 5-step guide from IDEAL POWER TOOLS. Featuring expert tips and high-quality visuals for flawless results.
Using the right tool is the first step. Using it with the right technique is what guarantees a professional result. Follow this simple checklist for clean, accurate holes every time.
- Choose Your IDEAL Tool & Bit: For brick, use an Impact Drill with a carbide-tipped masonry bit. For poured concrete, use a Rotary Hammer with an SDS-Plus bit.
- Mark Your Spot & Depth: Use a pencil to mark your hole. For precise depth (critical for anchors), measure the required depth on your drill bit and wrap a piece of painter's tape to act as a visual stop guide.
- Create a Pilot Mark: Set your tool to "drill only" mode (if available) or use the lowest speed. Run the bit for a second to create a small dimple. This prevents the bit from "walking" across the surface when you apply full power.
- Drill with Proper Technique: Switch to hammer mode. Hold the tool firmly with both hands and apply steady, consistent pressure. Let the tool's hammering action do the work—don't lean on it with all your body weight.
- Clear Dust Frequently: Periodically pull the bit out of the hole while it's spinning to clear out dust and debris. This keeps the bit cool, reduces wear, and results in a cleaner hole.
⚠️ Safety First: A Pro's Advice
High-powered tools demand respect. Always wear safety glasses to protect from flying debris. For rotary hammers, hearing protection is a must. Most importantly, always use the auxiliary handle for a firm, two-handed grip to control the tool's powerful torque and prevent it from binding and twisting dangerously. For a complete breakdown of essential safety measures, be sure to review our comprehensive Power Tool Safety Checklist.

Your Key Questions Answered
Which is better for concrete: a rotary hammer or a hammer drill?
For poured, solid concrete, a rotary hammer is always better. For lighter-duty concrete block or brick, a powerful hammer drill (impact drill) is perfect.
If I can only buy one tool, which should I get?
For the vast majority of DIY and home repair jobs, a powerful, high-quality impact drill like the IDEAL ID 950RF is the best single tool to own. It offers the most versatility, allowing you to drill in wood, metal, and most masonry.
Are rotary hammers worth it for home use?
For most home DIY projects, a high-quality impact drill is the more versatile and cost-effective choice. If you have a single, large project like removing a tile floor or drilling many holes in a foundation, a rotary hammer is worth the investment.
Can I use regular drill bits in an SDS drill?
No. A rotary hammer requires special SDS bits that lock into its slotted chuck. Regular round-shank bits will not fit and would be unsafe.
What jobs require a rotary hammer?
Jobs that require a rotary hammer include drilling multiple or large-diameter holes in poured concrete, setting anchor bolts in a foundation, light demolition work like removing tiles, and chipping channels in masonry.
What’s the difference between SDS-Plus and SDS-Max?
SDS-Plus is the most common standard, used on rotary hammers like the IDEAL ID HD2-26SRE for drilling and light chipping. SDS-Max is a larger, more robust system for bigger demolition hammers, which are specialist tools designed for heavy-duty breaking.
Why did my old hammer drill burn out?
Drills often burn out from being used on a job that's too demanding for them, like trying to force a standard hammer drill through thick, poured concrete for an extended period. This creates too much heat and overloads the motor. Using the right tool for the job prevents this.
Why won’t my drill go through concrete?
If your drill stops making progress, you have likely either hit a piece of steel rebar or the tool lacks the necessary impact energy. If it's rebar, you must move your hole. If it's a lack of power, you need to switch from an impact drill to a rotary hammer.
What do I do if my drill jams or binds?
Stop immediately. A jam can cause the tool to twist violently, leading to wrist injury. High-quality rotary hammers have a safety clutch to prevent this. To resolve it safely: 1) Unplug the tool. 2) Switch the tool to reverse rotation. 3) Attach a wrench to the chuck (if possible) or the bit itself and carefully work it back and forth to loosen it.
What maintenance does a rotary hammer need?
Basic maintenance is simple but critical for a long service life: keep the tool clean, ensure the air vents are clear of dust, and occasionally apply a small amount of grease to the shank of the SDS bits before inserting them, as specified in the user manual.
