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.

Amazon.com

The Bosch 1-1/8-Inch SDS-plus Rotary Hammer offers the ideal combination of power, impact energy, drilling speed, and comfort. It features vibration control for superior performance, and an excellent power-to-weight ratio for fast chiseling and drilling. It also provides three modes of operation--rotary hammer, hammer only, or rotation only--and an integral clutch to make this tool more versatile. The hammer comes with an auxiliary handle and a carrying case.

Two-Step Vibration Control
The rotary hammer provides vibration control without compromising performance. It reduces vibrations via a two-step process, originating from the impact mechanism and progressing to the handle, which features rubber dampening elements on the top and bottom.

Excellent Power-to-Weight Ratio with Variable Speed Trigger
Powered by an 8-amp motor, the hammer weighs 7.7 pounds and provides 2.6 ft./lbs. of impact energy, making it the one of the best rotary hammers in its class.

For better control and accurate bit starting, the rotary hammer boasts a variable speed three-finger trigger (0-4,000 bpm; 0-900 rpm).

Three Modes of Operation for Versatile Use
The rotary hammer offers three modes of operation. Use the multifunction selector to choose rotary hammer, hammer only, or rotation only mode. An integral clutch helps minimize torque reaction, and a 360-degree auxiliary handle further enhances project flexibility.

Warranty Information
The Bosch 1-1/8-Inch Rotary Hammer is backed by a manufacturer's one-year limited warranty.

What's in the Box
Rotary hammer, auxiliary handle, and carrying case.

WOW! I can't believe I've lived without a hammer drill this long!
5 Stars
WOW! I can't believe I've lived without a hammer drill this long!
I had never used a real hammer drill before. Not sure why. I wanted to split an overhanging end of a granite step, so I ordered some 1/2" feathers and wedges and borrowed a neighbor's Bosch Bulldog drill. OMG! That was so easy I couldn't believe it. I just had to get one for myself.I didn't do too much research, but I did discover that the "1-1/8" size is the maximum drill bit size that the drill is rated for. I don't know what material they rate that, but it's all relative, so the larger the more powerful the drill is. This drill seemed like a good price point for me and I liked the vertical format over the horizontal of the Bulldog.I've now drilled and split a number of granite blocks, some 10" thick using this drill and a 1/2" carbide bit (Bosch HCFC2081 1/2-Inch by 4-Inch by 6-Inch SDS-plus X5L Drill Bit) that I also got from Amazon. I've also drilled and split a number of foundation stones in front of my barn. Those were difficult to split, but each hole took about 30 seconds to drill.Let me assure you that this drill and a 1/2" carbide bit will drill a six inch hole in a stone or a block of granite in 30 seconds. I drill 18 holes down the middle of a six foot block in a matter of minutes. What's more, there's no need to push on the drill. I just hold it upright and let the weight of the drill and the hammer action do all the work! This means you can work for hours drilling with no fatigue.I also used the chisel action to remove a 100 square foot area of pavement with an asphalt/stone underlayment. For that i used a chisel (Bosch HS1470 SDS Plus Viper Long Life Chisel) that I got from Amazon. I think this was pushing it for the drill. It's not really a jackhammer, of course. I got the job done, but it took quite a while and was a tiring job. The chisel bit sacrificed its life for the job, as well. My neighbor says it should have been easier with a pick, but it's too late for me to know. I don't think you should expect a drill this size to handle hard code chiseling demo work.The SDS PLUS chuck is "ok". It's a bit tricky to get the bit seated, but it's not enough of a problem to influence my recommendation. I didn't realize there's an SDS MAX chuck. Not sure if it's just in more expensive drills, but it might be worth a look for you. I suspect bit price and availability should play a big role in your decision of chuck, though.
