Highly recommended for contractors, masons, plumbers, and general construction pros.
Introduction: Why the Bosch 11335K Matters
Demolition work is unforgiving. The wrong tool turns a one-day job into a three-day nightmare, wrecks your body with vibration fatigue, and leaves you with a tool that feels more like an anchor than an asset. The Bosch 11335K Jack Breaker Hammer was designed specifically to solve those problems. It sits in the sweet spot between underpowered demolition hammers that struggle with thick concrete and 70-pound pneumatic monsters that require a crew to move.
This is a 35-pound class breaker hammer built around a simple philosophy: give operators the highest possible impact energy for the lowest possible weight. At 38 pounds, it is the lightest and most compact breaker hammer in its class, yet it punches with 22 ft.-lbs. of impact energy and 1,300 blows per minute. That power-to-weight ratio is not marketing fluff—it is the reason this tool has remained a jobsite staple for years.
Whether you are a plumber trenching through a foundation, a mason removing brick, a general contractor prepping a site, or a homeowner tackling a major renovation, the 11335K offers a rare combination of raw force and genuine usability. This review breaks down what makes this tool tick, where it excels, where it falls short, and whether it deserves a spot in your arsenal.
Bosch 11335K Specifications and Technical Breakdown
Before diving into real-world performance, here is what you are working with:
| Specification | Detail |
|---|---|
| Model | Bosch 11335K |
| Motor | 15.0 Amp, 120V |
| Impact Energy | 22 ft.-lbs. (EPTA) |
| Blows Per Minute | 1,300 BPM |
| Weight (Tool Only) | 38 lbs. |
| Chuck Type | 1-1/8 in. Hex |
| Tool Retention | Two-way (accepts Bosch 1-1/8 in. hex steel + standard 1-1/8 in. air steel) |
| Vibration Control | Yes – elongated air cushion in hammer mechanism + shock-absorbing top handle |
| Auxiliary Handle | 360° articulating |
| Housing | All-metal housing and metal tube |
| Carrying Case | Included, with wheels |

The 15-amp motor is the heart of this machine. It draws enough current to deliver consistent power without the voltage drop issues that plague lower-amperage tools on long extension cords. The 22 ft.-lbs. of impact energy is class-leading for a 35-pound tool—most competitors in this weight range deliver 15–18 ft.-lbs., which means the Bosch removes material faster and with fewer passes.
The 1,300 BPM strike rate is well-calibrated. It is fast enough to pulverize concrete efficiently without being so rapid that the bit skates across the surface. The 1-1/8 in. hex chuck is the industry standard for this class, and the two-way retention system is a practical touch—it means you can use Bosch-branded bits or standard air tool steel with a retaining collar, giving you flexibility and saving money on consumables.
Power-to-Weight Ratio: Why 38 Pounds and 22 Ft.-Lbs. Is the Magic Number
The standout specification of the Bosch 11335K is not any single number—it is the relationship between them. At 38 pounds, this is the lightest breaker hammer in its class. At 22 ft.-lbs., it delivers impact energy that rivals tools weighing 50% more. That ratio matters more than most buyers realize.
A heavier jackhammer does not automatically mean better performance. Excess weight increases operator fatigue, makes horizontal work miserable, and limits how long you can run the tool before needing a break. The Bosch 11335K avoids that trap. You can lift it into a truck bed without a crane. You can maneuver it in tight basement corners. You can run it for hours without feeling like you went ten rounds with a heavyweight.
In testing by Bob Vila, the 11335K earned a 5/5 performance rating and a 4.5/5 value score. The tester noted: “When I started this one up I knew it could obliterate anything. It went through concrete, asphalt, everything I threw at it without an effort on my part. I felt like I got the power of an industrial jackhammer without being shaken to pieces.” That quote captures exactly what this tool is about—industrial power, manageable package.
For context, the general rule of thumb for concrete removal is 10 pounds of tool weight per inch of concrete thickness. At 38 pounds, the 11335K is rated for roughly 3–4 inches of standard concrete, but in practice, its high impact energy lets it punch above that weight class. It will handle thicker slabs—you will just need more time and patience. For foundation removal, asphalt trenching, and brick demolition, it is more than adequate.
Bosch Vibration Control: Extended Use Without the Punishment
Vibration is the silent killer of productivity in demolition work. Hand-arm vibration syndrome (HAVS) is a real occupational hazard, and even short of medical concerns, excessive vibration simply wears operators down faster. The Bosch 11335K addresses this with a multi-layered Vibration Control system.
The hammer mechanism itself uses an elongated air cushion that absorbs shock before it ever reaches the handle. The top handle is shock-absorbing and has a “springy” feel when compressed, which further dampens vibration transfer. Bosch claims the system reduces vibration by up to 40%, and while independent verification of that exact figure is difficult, the real-world difference is noticeable.
The 360° articulating auxiliary handle is another ergonomic win. It locks into position at virtually any angle, which means you can maintain proper body mechanics whether you are working vertically against a wall, horizontally on a floor, or at an awkward angle in a trench. That adjustability is not a luxury—it is a safety feature. Poor grip angles force compensatory muscle strain and increase the risk of the bit binding or kicking back.
After several hours of continuous use, the difference between the 11335K and a non-vibration-controlled breaker hammer is stark. Your hands do not go numb. Your shoulders do not ache. You can work longer shifts with less recovery time, which translates directly to higher daily output and lower long-term injury risk.
Build Quality and Durability: All-Metal Construction for Real Jobsites
Demolition tools live hard lives. They get dropped, kicked, rained on, and coated in concrete dust. The Bosch 11335K is built to survive that reality. The housing is all-metal. The hammer tube is metal. Even the carrying case is a hard-shell design with metal latches and wheels.
The grease-packed gearbox and hammer mechanism are sealed against debris ingress, which is critical because concrete dust is abrasive and will destroy unprotected internals. The Service Minderbrush system is a smart addition—it automatically shuts the tool down when the brushes wear to a point where maintenance is required. That prevents catastrophic motor damage and gives you a clear signal that it is time for service rather than letting the tool fail mid-job.
The wheeled carrying case is genuinely useful, not an afterthought. At 56.5 lbs. total weight with the case, it is still manageable to roll across a jobsite or lift into a truck. The case dimensions (17″ x 17″ x 20″) are compact enough that it does not dominate your vehicle or storage space.
One note on durability: the all-metal construction adds weight compared to plastic-housed competitors, but it is weight well spent. Plastic housings crack. Metal dents and keeps working. For a tool that is going to get knocked around, metal is the right call.
Real-World Performance: Concrete, Asphalt, and Brick
The 11335K ships with the HS2861 Star Point Chisel, which is the right bit for general concrete and asphalt breaking. The star point design concentrates force at the tip, creating fracture lines that spread outward with each blow. For floor tile removal, you would want a flat chisel (not included). For trenching, the included bit works well, though a moil point chisel might be preferable for very hard aggregate.
In concrete removal applications, the 1,300 BPM strike rate combined with 22 ft.-lbs. of energy produces a removal rate that is genuinely impressive for this weight class. You are not going to match a 70-pound Makita or a pneumatic jackhammer on sheer speed, but you are also not going to need a second person to help you move the tool or hold it steady. For residential foundations, driveway sections, sidewalk slabs, and pool deck demolition, the 11335K is fast enough that the time savings from easier handling often outweigh the slightly slower material removal compared to heavier tools.
For asphalt work, the lighter weight is actually an advantage. Asphalt is softer than concrete but stickier, and a heavier tool can bog down and require more operator effort to reposition. The Bosch bites in, shatters the asphalt, and moves on without fighting you.
Brick and masonry removal is where the in-line design really shines. Because the tool balances well at angles, you can use it horizontally against walls or at 45 degrees for stair demolition without the bit wandering. The articulating handle lets you brace the tool against your body for control without absorbing full vibration.
What Is Included in the Bosch 11335K Kit
The “K” in 11335K stands for kit, and Bosch includes everything you need to start working (minus extension cords and additional bits). The kit contains:
- The 11335 breaker hammer tool
- One HS2861 Star Point Chisel
- One 360° articulating auxiliary handle
- One grease tube for maintenance
- One wheeled carrying case
The star point chisel is a good general-purpose starting point, but most users will want to invest in additional bits. Flat chisels for tile and surface removal, moil points for hard concrete, and spade bits for trenching are common additions. The two-way retention system makes bit swaps quick and accepts both Bosch proprietary steel and standard 1-1/8 in. air tool steel, so you are not locked into expensive OEM consumables.
Bosch 11335K vs. Competitors: How It Stacks Up
The 35-pound demolition hammer category has several strong entrants, most notably the Makita HM1307CB. The Makita is a 14-amp tool with variable speed and soft start, and it is a respected machine in its own right. However, the Bosch 11335K holds advantages in impact energy (22 ft.-lbs. vs. lower figures in comparable Makita models) and the integrated Vibration Control system.
Where the Makita may appeal is in price—Bosch tools typically command a premium, and the 11335K is no exception. You are paying for German engineering, the power-to-weight ratio, and the durability of the all-metal construction. For occasional users, a lower-priced alternative might make sense. For professionals who run a breaker hammer weekly or daily, the Bosch pays for itself in reduced fatigue, faster job completion, and longer service life.
The XtremepowerUS and other budget brands offer lighter, cheaper options, but they lack the sustained power and build quality for commercial work. The 11335K sits in a tier where it is professional-grade without being industrial-overkill.
Who Should Buy the Bosch 11335K?
This tool is ideal for:
- General contractors who need a reliable breaker hammer for varied demolition tasks
- Plumbers trenching through concrete slabs and foundations
- Masons removing brick, stone, and mortar
- Asphalt and paving contractors doing repair and patch work
- Serious DIY homeowners with major renovation projects (foundation work, driveway replacement, pool removal)
It is overkill for occasional light-duty use. If you are removing one small patio slab every five years, rent a tool or buy a lighter demolition hammer. The 11335K is an investment, and it only makes sense if you will use it enough to justify the cost and storage space.
It is also worth noting that this is a 120V corded electric tool. You need a proper power source—ideally a 20-amp circuit, though it will run on 15-amp household circuits with a heavy-gauge extension cord. For remote jobsites without power, you will need a generator capable of handling the 15-amp startup draw.
