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

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 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.

This is another top notch tool by Bosch. I will admit, I am a homeowner/serious DIY type and not a contractor who uses this tool daily. However, with that said, this is still a quality tool. Very comfortable due to the vibration isolating design. It is somewhat loud though, so if drilling a lot of holes or chipping a lot of tile then ear protection would be good. The side handle is easy to position as is the depth gauge rod. I like that the chuck can be positioned in several different places to allow a chipping blade to be oriented properly. If you've used a regular hammer drill in the past you'll be amazed how fast a rotary hammer drills. I did several 1/2" holes in concrete to a depth of 8" and each one took less than 10 seconds. Granted, this was with a new bit but even still this is fast. A hammer drill would have taken forever, and not really been able to drill that deep efficiently. I've read that rotary hammers are not best suited to a lot of chipping duty, especially regular SDS tools like this. I've used it lightly in this application and I think for small jobs like chipping tile, or some concrete this tool wouldn't be harmed at all. I don't use this tool for regular drilling as it is best suited to hammer drilling and chipping. I have several other regular drills both corded and cordless for drilling so I can't comment on regular drilling capabilities here. The cord is quite long as with most Bosch tools I've purchased lately. Certainly a plus here. The ergonomics are good and the size relatively compact so it can fit into some tighter areas. Made in Germany.

Muy buena herramienta. Excelente desempeño.

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

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

Excelente herramienta hasta ahora, lo he ocupado para demoler un firme de concreto de 8 cm y bien, he ranurado y sin problema.
