User questions & answers

Question:	is enrh3203 better than enrh
Answer:	It expands to 3" (or approximately 3.3" inside a 0.35" thickness). So if your phone is 3" or less in width, it will hold it. The bracket swivels, so the phone can be orientated in any desired position.
Question:	How wide is the chisel bit that comes with this drill
Answer:	I wouldn't even call it an installation....it just has two prongs that hold onto a vent louvre. If you want to remove it, just pull and it slips right off, but stays put when in use.
Question:	Can this drill be used with a smaller 3/16 sds plus bit
Answer:	Yes it fits iphone 4 and all manufacturers that my family uses.
Question:	what type oil should I use
Answer:	We are using it with a 7plus and it works great. Our case is not bulky.

User questions & answers

Question:	would I be able to remove floor tile with this
Answer:	Ceramic tile I assume? This is a very powerful hammer drill. I use it to drill or bust thru all kinds of masonry products, poured concrete, blocks, brick, mortar etc.. It would have no problem with the tile, but you would have to be very careful not to damage the subfloor underneath, for tile typically some kind of cement board. This drill would easily punch thru that too. Check with a Home Improvement store or the Internet for a more appropriate tool/ technique. Otherwise I do endorse this product when used for the kinds of jobs designed for.
Question:	Is the case 100% plastic or is the silver part metallic
Answer:	Hello friend. The case is plastic and the silver part is aluminum
Question:	Is this strong enough to breakup the concrete walls of inground pool
Answer:	It possibly could be powerful enough, but it would surely take a long time. Better to rent a commercial tool for a job like this.
Question:	Hi sir, what is the difference between 'chisel' and 'hammer' functions? thanks
Answer:	The chisel doesn't rotate like a drill, but it still has hammer action.

User questions & answers

Question:	what is the difference in the Bosch 11321evs and 11264evs
Answer:	Without actually using each of the others, your question can't be answered. What I can tell you is that my son uses this hammer 12 hours a day alongside other men doing the same job. The others are envious of this hammer because it's so much easier to use than other hammers and doesn't cause as much physical discomfort as others can. When it wears out, it will be replaced with the same hammer. I hope this helps.
Question:	means what
Answer:	Made in China
Question:	Why is there conflicting info between amazon and bosch website on the impact energy. Bosch states 6.1 ft_lbs and amazon states 9.6 ft/lbs
Answer:	No, if your looking for a smooth face. Look for a finishing hammer.
Question:	What is the difference between the 11321EVS and the 11264EVS
Answer:	shipping has a cost. the more it weighs the more it costs.

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.

User questions & answers

Question:	What is the frequency of this hammer 50/60hz
Answer:	The D25951K has a weight of 41.300 LBS ( the whole kit). The tool itself weighs 29.3 LBS.
Question:	this makita include storage case
Answer:	It is a 15 amp motor. To figure out wattage- multiply the amp rating by 120 (in North America). For example, a table or miter saw rated at 15 amps will require around 1800 watts continuous, thus a 2500 watt generator, inverter or transformer would be the absolute minimum, with a larger unit being ideal. Also keep in mind- inverters, generators and transformers have widely differing designs and power quality.
Question:	Frequency of the tool I know it's 110v but what is the frequency 50/60hz
Answer:	The hammer is 29 pounds. Possibly the 40 pounds is referring to shipping weight.
Question:	How much does it cost the shipping and delivery to colombia...?¿.. Bogotá Colombia Latin America. Thnx
Answer:	Yes, the D25951K will include a kit box.

User questions & answers

Question:	Can this brake up a concrete driveway
Answer:	No, 110
Question:	is this exact same as the other red one by Xtremepower that cost more money
Answer:	Mine did not have any instructions or manual, I found some decent videos on youtube that explain how to set up and operate.
Question:	What is the weight of the demolition hammer by itself
Answer:	I was fine using it just under 100'. Rule of thumb ( I am not an electrician) is if you use the same ga. of extension cord as the product you should be ok? 200' is a long way though?
Question:	How many amps? I can't imagine this is really 2200 watts, b/c it wouldn't run properly on a 20 amp circuit
Answer:	Yes there are tamper attachments available. You can find it on Amazon with search terms "demolition jack - tamper shank". Check to make sure it will fit your make and model.

User questions & answers

Question:	Does any one knows how many joules and watts, I thought the more watts the more power? Thank you
Answer:	This Demo Hammer has 1240 watts but i do not know the joules. Heres some more information on this tool that can hopefully help you.* 110 V, 60 HZ * 1240 Watts * Impact rates: 1400 BPM * 360 degree swivel side handle * Includes: 2 pcs heavy duty chisels, glove, goggle * cord and plug is UL approved
Question:	Could this item be used to remove ceramic tile off concrete subfloor
Answer:	After reading the other answers, I would agree. This would get the tile off, but it is heavy and if you are not careful, damage will be done to the concrete subfloor. I did try this when removing the tile that was in our foyer, which was laid in a mortar bed around 1974. It went right through the tile, through the mortar bed and actually poked a little hole in the wood subfloor. After that, I went back to a hammer and chisel to remove the tiles, and mortar bed. Lot of work, but I didn't risk poking more holes in the wood subfloor.
Question:	It didn't come with a user's manual, where I can get one
Answer:	I do not recall any users manual in the original box . There was a sheet of instructions that dealt with various hazards that could arise as the device was put to use. Nothing more was included.
Question:	Can this jackhammer be used with OZ Post spacer and bit to drive t-4 post anchors into the ground
Answer:	Sorry, not familiar with OZ Post spacer/bit. I have only used the two bits (point and chisel) that come with the hammer, plus the spade (purchased separately). The hammer is heavy duty, and appears to accept standard bits, since the spade has 15/16" (23.8mm) diameter, 1 7/8" (49mm) long shank, below which is a 30 mm hex, 2 1/2" (70mm) long locking section. The locking-section's cut-out is 42 mm long and 4.5 mm deep. Most of my experience has been with the spade, which is driven into hard dry adobe soil very easily, and has saved my arms and back and rental cost several times over. My only complaint, thus far, is the small electrical cord. It is not heavy-duty and will get warm during continuous usage, as well as, shorten the life of the motor's two brushes.

Product features

Toolhounds know the old saying regarding a tool that does only one job, but does it like nothing else can. That’s certainly the case with this demolition hammer from Bosch. It may not be versatile, but it absolutely does its job.

This model is a favorite because it’s so user-friendly, weighing in at under 23 pounds and about as many inches in length – practically diminutive next to its competition. Its power, however, is not at all relative to its size, offering a range of impact energy from 4.4 to 18.4 ft./lbs. and up to 1,890 blows per minute, reducing tough concrete to dust.

Part of the beauty of this hammer is that it actually doesn’t want you to do the work for it; we found that exerting force on it actually slows you down. Instead, firm, steady pressure got us the best results. We particularly like the design of this hammer; instead of the traditional linear approach, Bosch built it more like a pistol, and that may (or may not, we’re not rocket scientists) be part of why so little vibration is felt. The rear handle is generously padded, and the auxiliary handle rotates 360 degrees so you can set it exactly where you need it. Another check in the ergonomics column comes from the electronic feedback system and the soft start it provides, keeping torque to a minimum.

Bit changes are fast and easy with the SDS-max system. Just twist the bit and push it in until it locks into place automatically, and you’re ready to work. The vario-lock is an ingenious feature that lets you position your spade or gouge at exactly the attitude you need. While in the vario-lock setting, you just rotate the locking sleeve to one of 12 positions at 30-degree increments, and an easy twist of the locking sleeve secures the bit in position.

The variable speed dial lets you choose from six speed settings, appropriate for chipping everything from plaster work up to concrete, and the circuitry will keep your set impact rate constant between no-load and load conditions.

It’s an investment, to be sure, but this tool will pay you back in spades.--Kris Jensen-Van Heste
