The Bosch 11335K jack breaker hammer delivers 22 ft.-lb. of impact force for the best material removal rate in its class. The 11335K has an excellent power-to-weight ratio at just 38 lb., and has an all-metal housing and metal tube for long-term durability. This breaker hammer is ideal for heavy-duty applications, such as breaking up asphalt and foundation removal. This breaker hammer features two-way bit retention and accepts Bosch 1-1/8 in. hex steel bits, as well as 1-1/8 in. air steel bits, for versatility.

How The Bosch 11335K Jack Breaker Hammer Compares To Other Demolition Hammer Options

Contractors evaluating how to handle concrete and asphalt breaking work usually face this question: should I stick with a lighter combination hammer for occasional chipping, step up to this lightweight, fast-cycling 35 lb. Jack breaker, or move to a heavier 63 lb. Brute-class breaker for maximum impact energy?

Here's the honest comparison:

Feature SDS-Max Combination Hammer (Light Chipping) Bosch 11335K Jack 35 Lb. Breaker Hammer Bosch Brute-Class 63 Lb. Breaker Hammer
Weight Lightest, under 27 lbs. 38 lbs., built for a strong power-to-weight ratio 63 lbs., heaviest of the three, built for maximum output
Impact Energy Lower, suited to light chiseling and drilling 22 ft.-lbs. of impact energy, best material removal rate in its class 35-43 ft.-lbs. of impact energy, higher raw power for the heaviest jobs
Cycle Rate Higher rpm/bpm range for drilling versatility 1,300 bpm, tuned for fast material removal at this weight class 1,000 bpm, geared toward maximum per-blow force
Portability Lightest, easiest to carry all day Wheeled carrying case keeps it fully mobile despite the added power Typically moved via a hammer cart rather than carried
Vibration Control Basic vibration mitigation Longer air cushion in the hammer mechanism plus a shock-reducing top handle Active Vibration Control with shock-absorbing or shock-mounted handles
Handle Design Auxiliary handle, limited articulation 360-degree articulating auxiliary handle for angled, horizontal, and vertical work Fixed ergonomic handles suited to a heavier, more stationary stance
Best Suited For Precision drilling with occasional light chipping Fast-paced outdoor asphalt work or indoor foundation removal needing mobility and speed Maximum impact energy for the heaviest foundation and pavement demolition

Why The Bosch 11335K Jack Breaker Hammer Is Worth The Investment

This isn't just a smaller breaker hammer, it's a purpose-built middle-weight option that delivers the best material removal rate in its class, giving contractors serious concrete-breaking speed without the bulk of a heavier Brute-class tool.

The 11335K specifically addresses the needs of contractors who need to move quickly between work areas on outdoor asphalt or indoor foundation jobs without sacrificing the impact energy those jobs demand.

Turns Fast Cycling Into A Faster Removal Rate. At 1,300 bpm and 22 ft.-lbs. of impact energy, this tool achieves the best material removal rate in its class for a hammer weighing just 38 lbs., letting contractors clear concrete and asphalt quickly without handling a heavier tool all day.

Built For Comfort On Long Demolition Runs

  • The Vibration Control system's longer air cushion in the hammer mechanism, paired with a shock-reducing top handle, cuts down on operator fatigue
  • A 360-degree articulating auxiliary handle provides a wide range of movement for angled, horizontal, and vertical work
  • All-metal housing, metal tube, and case add durability without adding unnecessary weight

Engineered For Reliability And Mobility On The Jobsite

  • Grease-packed gearbox and hammer mechanism deliver smooth, robust operation without jobsite lubrication guesswork
  • Service Minder brushes shut the tool down when brush replacement or preventative maintenance is needed, protecting the motor from damage
  • The included wheeled carrying case keeps the hammer, chisel, auxiliary handle, and grease tube fully mobile between job areas

Real Savings

  • A lighter, faster-cycling tool reduces operator fatigue and can speed up smaller-to-medium demolition jobs compared to a heavier breaker
  • Grease-packed components and Service Minder brushes reduce the ongoing cost of unplanned downtime
  • The included star point chisel, auxiliary handle, and wheeled case mean no separate purchases are needed to get started
  • Free shipping and no sales tax through Summit Forge Supply keeps the total cost down compared to buying elsewhere and paying tax and freight separately

The Bottom Line Contractors who need fast, mobile demolition power without the bulk of a heavier breaker can't rely on a light-duty combination hammer for outdoor asphalt or indoor foundation removal. The Bosch 11335K Jack Breaker Hammer is built with a fast 1,300 bpm cycle rate, vibration-reducing handles, and a wheeled carrying case, so it delivers the best material removal rate in its class at just 38 lbs. For anyone who needs speed and mobility without giving up real breaking power, this is the Jack built to handle it.
