Bosch Brushless Rotary Hammer with 4.0 AH Battery- 18 V - 1-in is rated 3.9 out of 5 by 8.
Rated 2 out of 5 by from Quality drill but only 5 min battery life. The drill works really well! ...for 5 minutes at a time. Good quality drill, but the "all day performance" claim they make on the box is misleading at best. You'll find yourself recharging the 4 amp battery constantly if you buy this drill. I confirmed with their help line that my battery was not defective and this is typical output one can expect when using a 1" drill-bit. I'm told they do make an 8 amp battery if you're planning on purchasing extra batteries. Personally, I returned the cordless and picked up the corded version + a 100ft extension cord for $20 less than the cost of the cordless. Hope this helps somebody.

Rated 5 out of 5 by from Working Mans Tool This hammer drill is made for the working man who uses his tools to pay his bills. This drill is on par to the corded 1/2 inch corded hammer drill I already own. The cordless feature makes using it on the job site very convenient. One note it has a SDS chuck and you will have to buy SDS compatible bits. they are worth it as they do not strip or spin when using the hammer function. I have not used it as a chipping hammer but it has that ability, and what I have used it for this feature will help you chip out and break up concrete. The battery holds a charge for quite a bit of work. Plan on buying another battery as soon as I can afford it. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Bosch GBH18v-26DK15 Cordless Hammer Drill Bosch GBH18v-26DK15 Cordless Hammer Drill I have used other hammer drills but I was a bit skeptical about a battery operated version. With the advent of brushless motors and lithium ion batteries, some battery operated tools are more powerful than the corded forefathers. The tool comes with one 18Vdc lithium ion 4.0 Ah battery, a quick charger, a depth set gauge, a second handle, and a carry case. The Battery is an 18 Vdc Lithium Ion 4Ah battery which is a sizable charge but not overly large battery. It should last most homeowners and some handy men more than long enough to do whatever you need to do. If you are drilling a lot of 1” holes in concrete, you may consider a second battery, but for most of us, the one battery is more than enough. A side note: The 18V battery works with the other 18 Vdc Bosch tools, so you can use it with other tools as well. The quick charger is a little large, but fits nicely in the carry case. It will charge the battery to full capacity in just over an hour (65 per the manual). The depth gauge is a easy to use by simply pressing a button and adjusting the depth you need. The second handle is adjustable 360° to make it convenient for just about any job. Since the drill is a bit long, the 2nd handle it handy for stability. The carry case is very durable and has a spot for a 2nd battery if you choose to get one. The tool itself is well made and has a number of options. The brushless motor is very powerful, but very efficient using battery power and has an overheat protection circuit. The drill has an anti-bind sensor to help prevent the bit from binding and having the drill rotate in your hand and injuring the operator. It can help save you from a very painful injury but it can stop the drill without notice. The chuck requires using the proprietary SDS chuck, but there is an adapter to use a standard hex bit. The adapter doesn’t allow the hammer function. There is a switch for hammer only, hammer drill and drill only. The trigger is variable speed and goes from 0 to 890rpms (reversible also). The hammer function provides 4350 pulses per second with 1.9 ft-lb of impact energy making it very effective penetrating masonry. The handle has fairly bright led light for illuminating the drill point. The handle fits in your hands comfortably and makes operating the large trigger easy. Overall the tool is well made, powerful, arrears to be very durable and is backed by Bosch with a 30 money back guarantee and a 3 year cordless tool protection plan. Pros: Hard case included, quick charger, light in the handle, push button easy to use depth gauge, overheat protection circuit, powerful Cons: Required proprietary SDS bits which may not be easy to find, the adapter doesn’t allow the hammer function. For this reason, I only gave it 4 out of 5 stars. Conclusion: I would recommend this tool if you don't mind being locked into the SDS bit system. [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Poor Product Bought this thinking that it would be able to handle making 18 6" deep holes in my concrete pad. Wrong! I charged the battery up as directed and was able to make 4 holes before it lost enough power to stop turning the bit on the 5th hole. Recharged the battery and it lasted 4 more holes. Recharged it and it did another 3 holes. Returned it and got a good wired Dewalt which drilled like butter. Would not recommend this to anyone. Very disappointed.

Rated 4 out of 5 by from If used only as a Cordless Hammer drill 5 stars. I attempted to use this cordless drill as a multipurpose drill in addition to its designed purpose. This rotary tool has a proprietary (SDS-Plus) chuck that will not accept standard hex bits. So I ordered an SDS-Plus adapter chuck. The Adapter allowed me to use my standard drill bits and my 3/8 and 1/2 socket adapters. I assumed this drill would have a decent amount of torque because of the low rotation speed, but "I think" the anti kickback shuts the drill off if it detects a "bind". (in accordance with the instruction manual) NOTE: The SDS adapter shown in the photos is not included. I had no issues using the hammer function but it does require SDS+ bits. (The hammer feature doesn't work with the SDS adapter installed) The carrying case is solid and should hold up well to common abuse. The light is bright and stay on for a few seconds after use. I've been using this as a drill for several weeks. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from So Powerful I cannot believe how much power this hammer has, I was skeptical at first but Bosch core battery seems to do the job with ease, Im a fan

Rated 5 out of 5 by from Powerful I replaced a 30 year old hammer drill and was stunned at the power of this. No cord is the best! Love it, buy one now. [This review was collected as part of a promotion.]
