Power Tools BOSCH 11335K Jack Hammer Review High Impact with Vibration Control

Description

Positive Features of the Bosch 11335K Jack Hammer Kit

Using the BOSCH Demolition Jack Hammer with 1-1/8-Inch Hex, 35-Pound Concrete Breaker (11335K) really impressed me with its power-to-weight ratio. Delivering 22 ft.-lbs. of impact energy while weighing just 38 pounds makes it stand out among heavy-duty demolition tools. The tool’s 15.0 Amp motor packs a punch with 1,300 blows per minute (BPM), enabling efficient removal of tough materials like concrete and asphalt without feeling like I was wrestling a beast. The all-metal housing and metal tube construction add a sense of durability that I could rely on during demanding tasks.

One feature that truly caught my attention was the Vibration Control system. The combination of a longer air cushion inside the hammer mechanism and a shock-reducing top handle made working with this tool surprisingly comfortable. I noticed less fatigue and could work longer stretches without the usual hand numbness or arm soreness that typically come with jack hammer use. The 360° articulating auxiliary handle offered versatile grip positions, letting me adjust for awkward angles, whether I was working horizontally or vertically.

The two-way tool retainer impressed me as well. It accepts standard 1-1/8 inch hex air tool steel with retaining collar or Bosch’s internal-locking combo steel, which gave me flexibility with bits depending on the job. The grease-packed gearbox and hammer mechanism ensured smooth, robust operation without any jerking or stalling, which I found essential for consistent performance. Plus, the Service Minderbrush system automatically reminds you when maintenance is due by shutting the tool down, a clever feature that keeps the jack hammer in top shape.

Key Benefits

• Powerful impact energy with manageable weight
• Effective vibration control for reduced user fatigue
• Versatile bit compatibility via two-way tool retainer
• Durable all-metal construction for tough job sites
• Smart maintenance alert system for longevity

Areas for Improvement on the Concrete Breaker

Despite its many strengths, the jack hammer had some downsides that I couldn’t ignore. The overall weight of 57 pounds (including accessories) might be a dealbreaker for some users, especially if they are not used to handling heavy demolition tools. I found it physically demanding during extended use, particularly for overhead or vertical work, even with the vibration control helping somewhat.

Handling the tool also required a bit of a learning curve. The in-line design, while great for tool balance, means you need to adjust your stance and grip carefully to maintain control during heavy-duty breaking. The carrying case, although convenient with wheels, was bulky and added extra weight when transporting the tool between sites.

I also noticed the price point might not be budget-friendly for casual users or homeowners. This is a tool clearly designed for professionals or serious DIYers who need powerful, reliable performance rather than occasional use. The lack of battery power means you’re tethered to a cord, which limits mobility somewhat, although the corded electric power source ensures consistent power without worrying about battery life.

Drawbacks

• Hefty overall weight challenging for prolonged use
• Bulky carrying case adds to transport load
• Corded power source limits mobility on some sites
• Learning curve in handling in-line design effectively

Versatility and Handling Features

The 360-degree articulating auxiliary handle deserves another mention. It provides ample operator control during demolition tasks, especially in tight or awkward spaces. I was able to position the handle at various angles, which made prying up concrete slabs or breaking sidewalks easier and safer. The shock-reducing top handle paired with this handle meant less vibration traveled to my hands, which helped me maintain a firm grip without excessive strain.

The tool’s compact style, despite its power, made it surprisingly manageable in cramped job sites. Its all-metal housing and tough composite material construction gave me confidence that it could withstand rough handling and harsh outdoor environments without cracking or wearing out prematurely.

I tested the two-way tool retainer feature extensively. Switching between Bosch’s internal-locking combo steel bits and standard hex bits was straightforward, saving me time and effort. This flexibility means you aren’t locked into proprietary bits, which can be an important cost-saving advantage on long projects.

Comparing to Popular Competitors

Checking out other demolition tools like the Makita HM1810 and the DeWalt D25980, the Bosch 11335K delivers a higher impact energy than many rivals, which translates to faster material removal. The Makita, while lighter, doesn’t quite match the 22 ft.-lbs. impact force Bosch offers, which became clear when breaking through thick concrete. DeWalt’s model has a similar power output but lacks Bosch’s Service Minderbrush maintenance system, which I found genuinely helpful for tool longevity.

On the downside, some competitors offer better ergonomics with lighter weights or cordless options, which Bosch does not provide. For example, Makita’s demolition hammer felt easier to maneuver for long hours, while Bosch’s tool shines in sheer power and durability. If portability and weight are your top priorities, a lighter competitor might be preferable, but for raw demolition force and built-in maintenance features, this model stands out.

Price to Quality Ratio

Considering what the jack hammer offers, the price performance feels justified for professionals who need high impact energy and durability. The robust 15 Amp motor and solid all-metal body promise longevity, making it a worthwhile investment if you frequently face heavy-duty demolition tasks. Casual users or those with lighter jobs might find it overkill and better served by smaller, less expensive tools.

The carrying case with wheels adds convenience for transport despite its bulk, and the maintenance reminder system likely reduces long-term repair costs. This tool feels like it was built with contractors in mind, delivering consistent power and durability without cutting corners. In that sense, it provides excellent value for money within its intended user base.

Build Quality and Durability

One thing I can’t stress enough is the solid build quality of this breaker. The all-metal housing and grease-packed gearbox create a machine that feels like it will last through many projects without breaking down. The tool’s composite materials also add strength without unnecessary weight, making it rugged enough for job site abuse.

My coworkers who saw me using it were impressed with the tool’s heft and balance, remarking that it felt like a professional-grade machine built for serious work. The shock-absorbing features also mean less wear on internal components, which should extend its usable life compared to cheaper models.

User Experience and Practical Use Cases

I shared this jack hammer with a friend who runs a small demolition business. He appreciated the ease of switching bits and the vibration control, saying it made tough jobs more bearable. On a recent outdoor asphalt removal project, the tool’s powerful blows made quick work of what would have been a grueling task with lesser equipment.

At home, I tested it on some old concrete slab removal and found the in-line design helped me maintain steady control, although it took some getting used to. The tool’s weight was noticeable, but the handles and vibration reduction features made it manageable enough for shorter sessions. Overall, it’s a beast of a machine that delivers professional performance but demands respect and proper technique to operate safely.

This thorough testing revealed a jack hammer that excels in power, durability, and user-friendly maintenance features but comes with trade-offs in weight and portability. The BOSCH Demolition Jack Hammer 11335K fits the bill for serious demolition work where performance and reliability come first.
