From the manufacturer

What Is Crystalline Silica?

Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials. The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles. These dust particles are very small and invisible to the naked eye. When inhaled, even in very small amounts, silica dust can cause serious health hazards. Each exposure to silica adds to the lung damage.

What Is Silicosis?

Silicosis is a disabling, irreversible, and sometimes fatal lung disease. When a worker inhales crystalline silica, the lungs react by developing hard nodules and scarring around the trapped silica particles. If the nodules become too large, breathing becomes difficult and death can result. There is no cure for this disease, but it is 100% preventable.

Get Compliant

Whether you are concerned about the health of your employees, your health, compliance or increasing productivity, Bosch has developed PRO+GUARD protection systems. In order to move toward compliancy and protection, it is critical that every component in the system is designed to effectively remove dust. Bosch dust collection systems can reduce airborne dust, helping to create a safer and healthier working environment.

Protect Yourself & Others

The Occupational Safety and Health Administration (OSHA) has issued a final rule to curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in Americaʼs workers by limiting their exposure to respirable crystalline silica. While using power tools with a dust attachment/ accessory and dust extractors with the right filter, exposure to silica can be drastically reduced. The new standard went into effect on June 23, 2016, and employers are required to comply with all obligations of the standard by June 23, 2017.

    Nice machineAwesome piece of equipment! I had preconceived idea that it would not stand up to my expectations being that it runs on 110 volts. It is exactly what I needed. Even with a 50 extension cord, it just keeps doing its job. If you want to tear up a street or something go rent one of those things big ones. but for sidewalks and driveways this thing earns its keep. I have busted up rock trying to digs post holes with it and it is amazing! I got the spade attachment and having seen the size of it I wondered if it would push its weight. It really impressed me. It also does light work and with the chisel bit you can trim concrete. The equipment is worth 5 stars…… It was delivered on time. However, it was not packaged. It was delivered in its own case, and the case has some shipping damage and was delivered to me less its wheels. Looks like they may have been on it at one time,but my problem is that i don’t see any way to contact the shipper…… I also wanted to add that I done some research on pricing to make sure that I was getting a good deal from Amazon. It was competitive but free shipping from amazon made it worth it. But…. The discount that Amazon shows is far from being true. The info says this item lists for over 2 grand but have yet to see a retail price anywhere more than 13 hundred.

    Does the jobI bought the Jack Hammer for two uses, tamping gravel in tight spaces, and driving fence posts. The device works fine for tamping gravel, but is challenging for driving fence posts. Lifting and holding the 40-lb jack hammer on top of a fence post is challenging, but it did drive posts into some compacted, hard dry clay. I would have been lucky to have driven the posts with a hand driver. I found that the shaft between the jack hammer and both the post driver and the gravel tamper is the same, but once it is used in the stake driving head, it was wedged in so tight I couldn’t get it out, and so I to get another shaft for the gravel tamper.

    The Bosch 11335K is a superb tool with multi-function versatility, ease of use, and nearly vibration freeI purchased this Jack Hammer for excavation when I ran into hard shale. Three features were the deciding factor in purchasing this tool.First, the anti-vibration technology is absolutely superb. All you need to do is place the bit where you want to work and hold the handle. You don’t have to push down as gravity assisted with the anti-vibration feature drive the bit into the rock. The hammer is fairly light for such a heavy duty tool.Secondly, using a 20 amp circuit and a heavy duty power extension cord eliminated the need for a heavy duty compressor and air line. This would easily work off of a generator.Finally, the choice of optional bits make this tool a multi-functional solution to many construction problems. I purchase the spoon attachment and in combination with the bit that came with the tool I was able to rapidly move through the shale and clay. I needed to drive a grounding rod and there is an attachment for that. And I needed to compact earth and rock so I purchased the tamper plate and shank. Changing the bits is a breeze.

    Great jackammer !!!this jackhammer is a little beast , ive had it for about four months , and its handled everything ive thrown at it , imho , it works just as good as the bigger electric models , yet its alot easier to hold for the angle cuts/chips , was a little skeptical at first but i just started my buisness a year and a half before buying this, and its what i could afford . It has saved me at least 350 in rental fees . pictured was a project where they had poured multple layers , 3 1/2 with wire mesh , and 1 1./2 por over that , with a heavy duty epoxy coating . ran the bosch all day and it hammered like a champ . i love this hammer , in the case , pick it up with one had , and away we go

    Right size but poor power switch designI’ve use this tool about total 10 hours to break concrete slap of 6″ and granite bolder about 10″ diameter. Tool is well built and the size and weight just perfect for my body (5’5″ 140lb). Can use the tool at 30 – 40 degree to the object and can not do this with the Brute breaker(too heavy for me). One thing I don’t light is the power switch design. It is an on/off rocker switch instead of the momentary switch like one on the Brute. The location is far away from the handle so I have to take one hand off the handle to turn it on or off. It makes controlling the tool hard. One star is removed because of this.

    Super product, which I should have bought soonerI purchased this tool to help make post holes in very rocky ground, after the post hole auger on the tractor was unable to get the job done.I had already rented a larger jackhammer and knew it would be to heavy to lift in and out of the holes. I was looking for something lighter, but could still get the job done.What is nice about this product is that it has turned out to be very useful on the farm, and I find myself using it far more than I thought. It comes in handy for breaking up concrete, trenching in our rocky soil and digging holes to plant trees.Everyone that uses it loves it.

  7. Good2Go

    Works great!I use this to dig fence post holes on my ranch in the hill country of central Texas where we have solid rock under 6″ of dirt. The low profile and light weight makes it easy to get down deep into the hole and pull it back out again. Makes quick work of breaking up granite. NOTE: I purchased separately the 

    Bosch HS2163B5 Narrow Chisel 1-1/8″ Hex Hammer Steel, 5 Piece, 20″

     and I find that I use this bit the most.

    Got my job done.I dug a French drain 50 feet long by 3 feet deep IN PURE ROCK. This hammer worked flawlessly. It is the perfect compromise of tool weight, tool mobility and chisel impact.

    Great tool! Out of the box it seems a …Great tool! Out of the box it seems a little weak but once I read the manual it states it can take a few minutes to warm up to full hitting power. The anti-vibe feature is excellent. Me and my crew ran it for a week straight busting up a slab and everyone was pleased with the performance. Not as hard hitting as the bigger Brute unit but still a great tool for the size.
