Key takeaways
- Brick and cinder block: approximately 1.5 to 2.5 joules is usually adequate for anchors and service penetrations. Use moderate pressure to avoid breaking the surrounding face.
- General concrete anchors: approximately 2 to 3.5 joules suits common holes from 1/4 to 3/4 inch.
- Frequent large holes: 3.5 joules and above improves drilling speed, especially in dense concrete, but increases weight and vibration.
- Very large penetrations or heavy demolition: consider SDS-Max rather than forcing an SDS-Plus tool beyond its intended range.
The best rotary hammers for masonry are the Makita XRH10Z for demanding cordless work, the Milwaukee M18 FUEL 2912-20 for high-output battery performance, the DEWALT DCH273B for lighter overhead drilling, and the Bosch GBH2-28L when a corded tool offers the best value.
Rotary hammers are different from hammer drills: their piston mechanism delivers substantially more impact energy, allowing an SDS-equipped bit to remove masonry rather than simply chipping at its surface. For brick, block, and concrete, compare impact energy first, then chuck compatibility, vibration control, weight, and the hole sizes you actually need.

Our picks by masonry situation
Best for large holes and hard concrete: Makita XRH10Z
The XRH10Z uses two 18V batteries and produces substantially more impact energy than compact SDS-Plus models. That makes it a strong choice for repeated drilling in reinforced or dense concrete, plumbing penetrations, and larger anchor holes. Its SDS-Plus chuck accepts common masonry bits, but the tool is heavy enough that it is less pleasant for occasional small holes or work above shoulder height.
Choose this model when drilling speed and capacity matter more than portability. For holes above roughly 1 inch, or for frequent work in hard concrete, stepping up to an SDS-Max rotary hammer may be more appropriate than asking an SDS-Plus tool to operate at its limit.
Best all-around cordless option: Milwaukee M18 FUEL 2912-20
The M18 FUEL 2912-20 balances a useful 2.1 foot-pound impact rating with a relatively manageable size. It offers hammer drilling, rotary-only drilling, and chiseling modes, so it can install anchors, drill through brick and block, and remove tile or mortar with the right chisel.
Its anti-vibration design is particularly valuable when a project involves many holes rather than one or two. It is a sensible choice for contractors who already own M18 batteries and for homeowners who want cordless convenience without moving to a larger two-battery machine.
Best for overhead and lighter work: DEWALT DCH273B
The DCH273B is one of the easier rotary hammers to control for overhead anchors, electrical boxes, and small plumbing penetrations. Its lower weight reduces fatigue, while its SDS-Plus chuck supports widely available bits from about 1/4 inch through its rated maximum.
It is not the best choice for constant large-hole drilling in hard concrete. Its advantage is control: for many users, a lighter tool that can be positioned accurately is more productive than a stronger tool that becomes tiring after several minutes.
Best corded value: Bosch GBH2-28L
The Bosch GBH2-28L delivers more power than most compact cordless models and does not slow down when a battery is depleted. Its cord is a disadvantage around finished spaces, but an extension cord is often cheaper than purchasing multiple high-capacity batteries.
This is a strong option for a workshop, basement renovation, or masonry contractor who drills for long periods near a reliable power source. Bosch’s vibration-control system helps make its higher output more manageable during extended use.
How to choose impact energy and drilling capacity
Impact energy, measured in joules or foot-pounds, describes the force delivered by each piston strike. More is not automatically better: excessive energy can damage soft brick, enlarge an anchor hole, or make the tool difficult to control.
- Brick and cinder block: approximately 1.5 to 2.5 joules is usually adequate for anchors and service penetrations. Use moderate pressure to avoid breaking the surrounding face.
- General concrete anchors: approximately 2 to 3.5 joules suits common holes from 1/4 to 3/4 inch.
- Frequent large holes: 3.5 joules and above improves drilling speed, especially in dense concrete, but increases weight and vibration.
- Very large penetrations or heavy demolition: consider SDS-Max rather than forcing an SDS-Plus tool beyond its intended range.
Check the manufacturer’s recommended maximum diameter rather than treating it as a target. A tool rated for a 1-inch hole may drill that size, but repeated holes near the limit create more heat, wear, and fatigue than holes in the 3/8- to 5/8-inch range.
SDS-Plus versus SDS-Max chucks
SDS-Plus is the practical choice for most residential masonry. It uses smaller bits, releases them quickly without a chuck key, and covers common anchor, conduit, and fastener holes. Bits are generally easier to find and less expensive.
SDS-Max uses a larger shank and is designed for higher-impact tools, larger bits, core drilling, and demolition. The trade-offs are greater tool weight, higher purchase cost, and more expensive consumables. A homeowner drilling six 1/2-inch anchor holes does not benefit from SDS-Max capacity.
Do not use a standard round-shank masonry bit in an SDS chuck unless the manufacturer provides a suitable adapter. Adapters can add wobble and are not a substitute for the correct SDS bit when hammer action is required.
Decision matrix: match the hammer to the job
| Your situation | Recommended type | Useful specification | Why |
|---|---|---|---|
| Occasional homeowner use | Compact SDS-Plus | 1.5–2.5 joules, 6–8 lb | Enough for anchors without unnecessary bulk |
| Weekly renovation work | Midrange cordless SDS-Plus | 2–3 joules, anti-vibration system | Balances mobility, comfort, and output |
| Daily drilling near outlets | Corded SDS-Plus | 8–9 amps, 2.5–3.5 joules | Consistent output and lower battery expense |
| Frequent hard-concrete drilling | High-output cordless or corded SDS-Plus | 3.5+ joules, roughly 1-inch capacity | Faster progress and better durability under load |
| Large penetrations or demolition | SDS-Max | 8+ joules, larger bit system | Designed for bigger holes and heavier chiseling |
Battery, cord, and ownership costs
A cordless rotary hammer is convenient, but the tool-only price is not the complete cost. A typical professional cordless package may run from roughly $250 to $600 depending on batteries and charger; corded SDS-Plus tools commonly range from about $150 to $350. Replacement high-capacity batteries can add $100 to $250 each.
For example, suppose a cordless kit costs $450 and is used for 150 projects. The tool-and-battery cost is $3 per project before bits and maintenance. A $220 corded tool used for 50 projects costs $4.40 per project, but it may become cheaper per use if it is used hundreds of times. The calculation changes if the cordless battery platform is already part of your tool collection.
Setup and maintenance that extend tool life
- Select the correct bit. Use SDS-Plus or SDS-Max bits matched to the chuck, preferably carbide-tipped bits for concrete and specialized masonry bits for brick.
- Mark hidden services first. Check for electrical wiring, plumbing, and embedded reinforcement before drilling. A rotary hammer can penetrate masonry quickly enough to reach hazards with little warning.
- Start slowly and squarely. Let the bit establish a shallow guide hole before applying full speed. Keep the tool perpendicular unless the bit manufacturer specifies otherwise.
- Clear dust from deep holes. Withdraw the bit periodically, or use dust extraction. Dust left in the hole can prevent an anchor from seating fully and increases bit friction.
- Grease the bit shank. Apply the small amount of grease specified by the manufacturer to the SDS shank, not to the flutes. Wipe away grit before inserting the bit.
- Inspect wear items. Replace blunt bits, damaged retainers, worn brushes on applicable corded tools, and cracked side handles. A dull bit transfers more heat and vibration into the hammer.
The parts that usually wear first are bits, the SDS chuck’s retaining components, carbon brushes on some corded designs, and battery packs on cordless models. Avoid leaning heavily on the tool: the hammer mechanism supplies the impact, while excessive pushing can slow the piston, generate heat, and reduce drilling performance.
Final recommendation
For most people comparing the best rotary hammers for masonry, start with a midrange SDS-Plus model offering about 2 to 3 joules, a side handle, depth stop, and effective vibration control. Select the DEWALT DCH273B for the lightest cordless handling, the Milwaukee M18 FUEL 2912-20 for a balanced cordless system, the Bosch GBH2-28L for sustained corded work, or the Makita XRH10Z when larger holes and hard concrete justify more impact energy. Move to SDS-Max only when your hole sizes, demolition work, or daily workload clearly require it.
