6 Best SDS Max Hammer Drills Compared: Impact Energy, Speed and Weight
An SDS Max hammer drill is required when SDS Plus tools stall – typically when you need to drill 3/4-inch to 2-inch diameter holes deeper than 12 inches, core up to 3-1/8 inches, or chip continuously with spade and point chisels. Compared to SDS Plus, SDS Max delivers 2x to 4x more impact energy per blow, uses a larger 18mm shank, and is built for sustained demolition. These six models represent the current top tier for concrete drilling speed versus all-day handling.
| Model | Power Source | Impact Energy (EPTA) | Blow Rate (BPM) | No-Load Speed (RPM) | Weight (tool only) | Optimal Drilling Range | Vibration Control |
|---|---|---|---|---|---|---|---|
| Hilti TE 60-ATC/AVR | Corded 120V | 6.4 J | 2,900 | 340 | 13.7 lbs | 5/8″ – 2″ | AVR + ATC |
| Bosch RH540M | Corded 120V | 6.5 J | 2,900 | 340 | 15.2 lbs | 3/4″ – 2-1/8″ | Vibration Control |
| Makita HR4013C | Corded 120V | 6.2 J | 2,900 | 250-500 | 14.8 lbs | 3/4″ – 1-9/16″ | AVT |
| DeWalt D25773K | Corded 120V | 7.1 J | 2,210 | 145-280 | 18.7 lbs | 3/4″ – 2-9/16″ | SHOCKS + E-Clutch |
| Milwaukee M18 FUEL 2717-20 | Cordless 18V (2x 6.0Ah) | 4.0 J | 3,800 | 380 | 12.4 lbs (with 2 batteries) | 1/2″ – 1-9/16″ | AVS + AUTOSTOP |
| Metabo HPT DH52MEY | Corded 120V | 6.0 J | 2,800 | 300 | 14.3 lbs | 5/8″ – 2″ | UVP + AHB |
Best Picks by Job Type
1. Hilti TE 60-ATC/AVR – Best Overall for Fast 2-Inch Holes With Control
The TE 60 remains the benchmark for sds max hammer drill performance because it pairs high impact energy with Hilti’s Active Torque Control and Active Vibration Reduction. At 6.4 joules and 2,900 BPM, it drills a 1-1/2-inch x 12-inch hole in 4,000 PSI reinforced concrete in roughly 45-60 seconds with a sharp four-cutter bit, while keeping vibration at 9.5 m/s². Three modes – rotary drilling, hammer drilling, and chiseling with chisel rotation – make it versatile for anchor holes and light demolition. Weight at 13.7 pounds makes overhead chipping far less fatiguing than 18+ pound demolition-focused models. It is a premium-priced platform in the general market range of $900 to $1,100 for the bare tool.
2. Bosch RH540M – Best Value Corded Power
The Bosch RH540M delivers 6.5 joules at a lower price point in the general range of $400 to $550. It uses the same core class as the Hilti but with a simpler fixed-speed motor and Bosch’s Vibration Control in the main and auxiliary handles. It is slightly heavier at 15.2 pounds and lacks active torque control, so it relies on a mechanical slip clutch. For shop and site work where you need maximum drilling speed per dollar and already own SDS Max bits, it is the most efficient choice. The RH540M excels at thru-holes for 1-1/2-inch and 1-3/4-inch anchors.
3. Milwaukee M18 FUEL 2717-20 – Best Cordless SDS Max Hammer Drill
If you need to drill 1-inch to 1-1/2-inch holes away from power, the cordless Milwaukee 2717-20 is the clear leader. Its 4.0 joules and 3,800 BPM blow rate trades single-blow power for blow frequency, which keeps drilling speed competitive up to 1-3/8 inches. Expect approximately 35-45 holes of 3/4-inch x 3-1/2-inch per charge with a pair of M18 High Output 6.0Ah batteries, dropping to 12-15 holes at 1-1/2-inch diameter. At 12.4 pounds ready to work, it is the lightest option for overhead work and the only one that eliminates cord management on scaffolding or foundations. For true 2-inch drilling and all-day chipping, corded models remain faster.
4. DeWalt D25773K – Best for Demolition and Large Cores
The DeWalt D25773K is a heavier 1-7/8-inch combination hammer built for demolition-first users. Its 7.1 joules is the highest here, but its lower 2,210 BPM means it chips more aggressively per blow rather than drilling small holes faster. It handles 2-9/16-inch solid bits and up to 5-inch core bits with its 145-280 RPM range, making it ideal for large penetrations for plumbing and electrical. At 18.7 pounds, it is not an all-day overhead drill, but for horizontal chipping, bushing, and foundation breakout work, the mass works in your favor. Includes SHOCKS vibration system and E-Clutch anti-rotation.
5. Makita HR4013C – Best for Low Vibration and Finish Work
Makita’s HR4013C uses Anti-Vibration Technology (AVT) with a counterbalance and vibration-absorbing housing to achieve the lowest vibration in its class at 8.5 m/s², which matters for extended chipping. Its variable speed dial (250-500 RPM) gives better control when starting large bits or drilling in hollow block. Impact energy is 6.2 joules, nearly identical to the class leaders. The soft-start and torque limiter add safety when bits bind in rebar. Weight is balanced at 14.8 pounds.
6. Metabo HPT DH52MEY – Best Mid-Weight All-Rounder
The Metabo HPT DH52MEY (formerly Hitachi) offers 6.0 joules, User Vibration Protection (UVP), and an aluminum housing motor for durability at a mid-range price in the general range of $500 to $700. It drills to 2 inches and cores to 3-1/8 inches, with a 12-position chisel rotation. At 14.3 pounds, it sits between the Hilti and Bosch in handling. It is a strong alternative if availability or pricing for the top three is an issue, with identical SDS Max bit compatibility.
Decision Matrix: Which SDS Max Drill Matches Your Work?
| Your Situation | Choose This | Why |
|---|---|---|
| Drilling mostly 1″ to 2″ anchor holes in reinforced concrete, daily use | Hilti TE 60-ATC/AVR or Bosch RH540M | Highest joules-per-pound ratio and sustained 2,900 BPM for fast penetration without excessive weight |
| Chipping tile, stripping concrete, or bushing 4-6 hours per day | Makita HR4013C or DeWalt D25773K | Lowest vibration (Makita) or highest single-blow energy (DeWalt) reduces operator fatigue and speeds material removal |
| Need mobility on remote slabs, rooftops, or no generator access | Milwaukee M18 FUEL 2717-20 | Cordless operation and lightest carry weight; accept slower speed above 1-1/2″ |
| Core drilling 2-1/2″ to 5″ penetrations for pipe | DeWalt D25773K | Largest rated core capacity and 7.1 J impact energy to drive large core bits |
| One tool for occasional 1″ holes and teardown, limited budget | Bosch RH540M or Metabo HPT DH52MEY | Full SDS Max capability at lowest corded price range without sacrificing 6+ joules |
Impact Energy vs. Blow Rate: What Actually Drills Faster?
Impact energy (joules) and blow rate (BPM) work together. Joules determines how much concrete fractures per impact; BPM determines how many impacts occur per minute. A drill with 7.1 J at 2,210 BPM, like the DeWalt, hits harder but less often than a 4.0 J at 3,800 BPM cordless model.
For holes under 1-1/4 inches, higher BPM often wins because the smaller bit cross-section needs less energy per fracture. For holes from 1-1/2 to 2 inches, higher joules wins because more material must be pulverized per rotation. This is why the 6.0-6.5 J corded models drill 2-inch holes 30% to 50% faster than 4.0 J cordless models, even though the cordless models have a higher BPM. If your work is mostly 3/4-inch to 1-inch, you may not need SDS Max at all – a large SDS Plus rotary hammer at 3.0-3.5 J will be lighter and faster.
Ownership Realities: What Wears Out and What Costs Extra
An SDS Max hammer drill is durable, but consumables and maintenance determine real cost.
- Grease and service interval: Hammer mechanisms require grease replenishment every 50-80 hours of hammering. Most models have a service indicator. Running dry causes premature striker and piston wear and a noticeable drop in impact.
- Bushings and seals first: The tool holder bushing and dust seals wear before the motor. Dust ingress from overhead drilling is the primary killer. Use a dust extraction attachment and wipe the shank clean before inserting.
- Bits and chisels are consumables: A four-cutter carbide SDS Max bit lasts approximately 80-150 holes in 4,000 PSI concrete at 1-1/2-inch diameter before cutting speed drops sharply. Rebar hits chip carbide edges instantly. Budget for bit regrinding or replacement as a core operating cost.
- Vibration and carbon brushes: Models with AVT/AVR systems need their dampers inspected after heavy chipping seasons. Brushed motors (Bosch, Metabo HPT) will need brush replacement around 200-300 hours; brushless models (Milwaukee) eliminate this.
- Common mistake: Using SDS Max drills in rotary-only mode with excessive pressure. Let the hammer do the work – pushing harder does not increase BPM and overheats the bit. Use light, steady feed and let dust clear from the flutes.
How to Choose the Right SDS Max Size for Your Work
Do not buy by maximum drilling diameter alone. Check the optimal range in the table above. A drill rated to 2-9/16 inches will be heavy and slow for continuous 3/4-inch work. If you drill 2-inch holes only occasionally but chip daily, prioritize weight and vibration (under 15 pounds, under 10 m/s²) over an extra 0.5 joules. If you core over 3 inches, you need a drill with low RPM (under 300) and high torque to prevent core bit binding. Always verify the SDS Max hammer drill you choose has the mode you need – some demolition hammers only hammer, without rotation.
FAQ
Can I use SDS Plus bits in an SDS Max hammer drill?
No, not directly. The shanks are different diameters (10mm vs 18mm) and are not interchangeable. An adapter exists but it adds length, runout, and reduces impact energy transfer. If you need both sizes regularly, own one quality SDS Plus and one SDS Max tool rather than adapting.
Do I need SDS Max for a 1-inch hole?
Usually no. A powerful SDS Plus rotary hammer at 2.5 to 3.5 joules will drill a 1-inch hole faster and with less weight. Choose SDS Max when you consistently drill 1-1/4 inches and larger, or when you need hours of chipping without overheating a smaller tool.
How long does an SDS Max drill last?
With proper greasing and dust control, the hammer mechanism typically lasts 5 to 10 years of professional use before a rebuild. Motors and electronics often outlast the striker assembly. The most common end-of-life is worn tool holder play that causes bit wobble and lost impact.
