ENEACRO Demolition Jack Hammer 14.5Amp SDS-Hex Concrete Breaker, 65 Joules Heavy Duty Chipping Hammer Cement/Pavement/Floor Breaker, with 2pcs of chisels and Carry box with Rollers

Why I reached for this jack hammer

I had a run of concrete-heavy jobs this season—a crumbling patio, a section of sidewalk that had heaved, and a few stubborn masonry footings. Rather than rent repeatedly, I gave the ENEACRO jack hammer a shot. It’s a 1700W, 65‑joule corded breaker with an SDS‑hex bit system and a rotating side handle. I’ve now used it across several projects, both horizontal and vertical, and it’s proven to be a straightforward, hard-hitting tool with a few thoughtful touches—and a couple of compromises to be aware of.

Setup and first impressions

Out of the wheeled case, the tool feels solid with its aluminum gearbox housing and stout handles. The case includes a pointed chisel, a flat chisel, spare carbon brushes, lubricant, a small oil bottle wrench, and hex wrenches. I appreciated not having to chase basic accessories on day one. The case itself is bulky but tough, and the built-in wheels matter more than you’d think when you’re moving a breaker and bits around a jobsite.

The SDS‑hex chuck locks bits firmly with a positive, tool‑free engagement. No fiddling or guesswork—push in, twist to lock, and it’s ready. Before powering up, I checked the oil level and added the provided lubricant per the manual. That’s a step worth making a habit; this class of tool performs best and lasts longer when you’re diligent about lubrication.

Power and breaking performance

On the slab and sidewalk jobs, the breaker’s 65 joules (about 48 ft‑lbs) of impact energy showed up immediately. With the pointed chisel, I could start fractures quickly, and the flat chisel widened and lifted sections without excessive binding. On 4–6 inch concrete, it’s in the sweet spot—fast enough to keep the workflow moving while still controllable. Areas with dense aggregate or thicker sections certainly slow any breaker, but this unit maintained confidence-inspiring pace. Around rebar, it’s best to crack around the steel with the point, then switch to the flat to feather pieces away rather than trying to brute‑force through the bar.

For wall and footing work, the rotating handle helped me orient the tool for leverage and body position. The motor keeps a steady cadence under load, and the breaker doesn’t feel like it’s bogging unless you lean too aggressively. As with any demolition hammer, letting the tool’s weight and hammer mechanism do the work is key—pressing hard only increases fatigue and heat.

Vibration, control, and ergonomics

Budget demolition hammers can be punishing on the hands and forearms. This one’s vibration control is better than I expected. The shock‑absorbing handle does reduce the high‑frequency buzz, and the 360° rotation lets you set a natural wrist angle whether you’re working horizontally or chipping vertically along a wall. Is it as isolated as premium systems on top-tier pro models? No. After long sessions, you still feel it. Good gloves and pacing your work remain essential. But for a tool in this class, the vibration control is genuinely helpful and reduces end-of-day fatigue.

The trigger lock-on is also practical. On long runs, being able to set it and focus on stance and bit placement instead of maintaining trigger pressure is a nice touch. The main grip has enough texture to stay planted even with dust and sweat in the mix.

Bits and the SDS‑hex system

The included pointed and flat chisels cover most demolition tasks—starting fractures, prying up sections, and general chipping. Retention has been reliable; I didn’t experience any bit walk-out. When shopping for additional bits, make sure they’re explicitly SDS‑hex compatible. A clay spade or asphalt cutter expands what you can do with compacted soil or thin asphalt overlays. Edge retention on the included chisels is decent; I touched them up after heavier sessions and they’ve held up fine.

Bit changes are genuinely quick, which helps when alternating between point and flat profiles to keep speed up and minimize stuck moments. The dust protection in the chuck has kept the interface crisp; a quick wipe before insertion is still a good habit.

Portability and storage

This is a heavy tool, and the case earns its keep. Rolling it from the truck to the work zone reduces the awkward lifts. Inside the case, there’s a designated spot for each accessory, and it’s tough enough to live in a crowded trailer without cracking. The cord length is serviceable for most garage or driveway jobs; on sites, I used a 12‑gauge extension for safety and to avoid voltage drop.

Maintenance and durability

This breaker asks for basic care: keep an eye on oil, clear dust from vents, and be ready to swap carbon brushes when performance drops. The spare brushes included make that process painless, and access screws are easy to reach. After one particularly dusty day, I noticed a light oil film around the fill plug—turned out I’d been overzealous with topping off. Keeping the level within the recommended mark and wiping the area before storage solved it.

Heat management has been reasonable. On extended breaking sessions, I gave it a breather every 15–20 minutes while hauling debris, and it stayed consistent without odd noises or loss of impact. The aluminum housing sheds heat better than plastic‑heavy designs, and the motor has held up well so far.

What I liked

• Strong, predictable impact energy for 4–6 inch slab and sidewalk work
• SDS‑hex chuck with positive, tool‑free bit changes
• Rotating handle and useful vibration reduction for better ergonomics
• Thoughtful kit: two chisels, brushes, lubricant, and a wheeled case
• Lock-on switch for long sessions and focused control
• Straightforward maintenance with easy access to wear parts

What could be better

• No power or impact rate adjustment—it's full-on all the time
• Still a heavy, noisy operation; PPE and pacing are mandatory
• The case is bulky; great for protection, but it takes space
• Oil level discipline matters; overfilling can create seepage around the plug

Practical tips from use

• Start with the pointed chisel to create relief cracks, then switch to the flat chisel to lift and shear sections.
• Let the hammer do the work—leaning too hard reduces control and increases vibration and heat.
• For reinforced areas, work around rebar rather than directly at it; a recip saw with a metal blade or cutoff wheel can speed removal of exposed bar.
• Check oil before each major session, and keep the chuck clean to maintain tight bit fitment.
• Wear hearing protection, eye protection, gloves, and a dust mask or respirator. Use a GFCI‑protected circuit and a heavy‑gauge extension cord.

Who it’s for

If you’re a homeowner or small contractor facing periodic concrete, masonry, or compacted soil breaking, this tool hits a smart balance of power, price, and practicality. It’s overkill for delicate tile work or precision chipping, and it doesn’t replace a full-size road breaker for constant commercial use. But for patios, sidewalks, small pads, retaining walls, and trench starts, it’s a reliable, straightforward performer.

Recommendation

I recommend the ENEACRO jack hammer. It delivers real breaking power, a secure and convenient bit system, and enough vibration control to make full days manageable, all in a package that’s easy to transport and maintain. The lack of variable power is noticeable when you want finesse, and you do need to be mindful of oil level and general care. But judged on core performance and usability, it’s a strong value that has handled everything I’ve thrown at it without drama. If your work calls for dependable concrete and masonry demolition without the rental clock ticking, this breaker earns its spot in the kit.
