RH328VC 1-1/8 Inch SDS-plus Rotary Hammer with Variable Speed, Vibration Control

I use this hammer drill for work (rough & finish carpentry, remodeling). I use it primarily for drilling holes into concrete or masonry block. I've used the chipping only function once to remove some old ceramic tile floor, worked exceptionally well. The anti-vibration is great and easy on your hands. The case is ample sized for bit storage. I also picked up a Bosch SDS-to-adjustable-chuck adapter so I can use the drill only function for large holes in wood my cordless drill is not up for. If you're considering this drill versus a Hilti (like I was), save $200 and get the Bosch. It's made in Germany and has one year less of warranty compared to the Hilti (no biggie, all tools break and you get them repaired). *****update 12-30-2012****** Still using this hammer for my work tasks. It shows that the tool has been worked. The rubber impact cushion on the tip of the SDS chuck has cracked and needs replacing. I've done 3-4 tile floor demo jobs with the hammer in chip mode, so this is probably the reason for the crack. Using a Bosch tile scraper bit, I pry up with the hammer. I've done window, door, and sliding glass door installations. Chipped stucco and concrete. Drilled out 3/4" holes for epoxied 5/8" dai. anchor bolts in concrete tie beams and through wood plates with a long auger bit. I like the size of this drill because it fits into smaller spaces (between floor joists or wall studs) during framing applications and also is easier to install smaller windows with it (think 24" x 24" fixed glass windows or smaller). I use the depth rod quite often. The hard case has held up. I've got it jammed full of bits etc. The cord doesn't kink up and folds away well each time. The drill itself shows signs of wear on the body from being dropped and dragged. None of this effects it's performance. This tool is definitely professional grade.

Needed a hammer drill to bore a few holes in concrete, nothing super heavy duty, just a middle of the line hammer drill. This drill meets all these requirements and quite easily got the job done.. Rated 8 Amps there is little chance of tripping a 15 amp breaker. A medium duty extension can be used, the SDS-plus bits are not too expensive. The auxiliary handle can be adjusted with a twist, the depth gauge can be retracted, the variable speed is built into the on/off trigger. The reverse switch is a plus if/when bits get stuck and flips to either position verily easily. The multi function switch has 3 selections, rotation with hammer, hammer only or rotation only. With the purchas of a SDS-Plus shaft chuck, the drill will function as a normal drill with a 3 teeth 1/2 inch chuck so normal wood boring drill bits can be used. The SDS plus bits fit easily into the drill with just twist and push. A small tube of lubricant is included in the case to be applied to the slots on the SDS bit. A pull down on the chuck releases the bit. It has an integral clutch to minimize torque reaction. This high quality hammer drill meets all requirements without breaking the bank. In retrospect a purchase of a BOSCH SDS "MAX" hammer drill along with a SDS "MAX" to SDS "PLUS" chuck would allow the use of both SDS PLUS or SDS MAX drill bits. By purchasing the SDS PLUS drill only SDS PLUS bits can be used, I know of no adapters allowing for an SDS PLUS to SDS MAX chuck adapter - hope this suggestion is helpful.

I am a professional installer of communication products such as Lasers, Microwave and Millimeter Wave radios. I often mount these units to concrete parapets on buildings as they provide stable support. These mounts MUST be rock solid and reliable. They must be capable of withstanding constant winds of at least 135 mph. I would NEVER want one coming loose and falling on a person below. Needless to say, I sink a lot of Red Heads every day when mounting these devices. (Red Heads are inexpensive, people are not) After using and abusing several high end hammer drills, I will never use one again. They are slow, noisy, vibration prone, lack longevity. I went through 3 last year. The noise is highly intrusive to occupants of office paces and property managers become quite unfriendly. The Bosch SDS Rotary Hammer is the ticket. It's well designed, and cuts through even 4000 psi concrete quickly, quietly, with minimal fatigue. Now property managers love me, I make more money due to less labor costs, and every customer is a reference. I can easily shave an hour off my work day and I use fewer drill bits, with more consistent holes and less fatigue. I have enough vibration on my H-D, I don't need it on the job, too! Coupled with a good concrete epoxy, my mounts provide the quality I need and safety I demand. The Bosch SDS is an outstanding tool.

Muy buena herramienta. Excelente desempeño.

Purchased a few weeks ago and used it to take up 400sq ft of tiled floor. Did the job.

The power rating for this drill is 120volts. Most transformers on the market are 110volts, and quite costly when you factor extension cables. Rather buy the South African model GBH3-28.

Excelente calida de producto y muy durable

all good thanks
