what's the maximum size masonry bit this will take?

Asked by

June 1, 2014
I need a hammer drill that can accept a 1.5" carbide bit for masonry. This one actually -
Bosch HC5091 1-1/2-Inch x 16-Inch x 21-Inch Wild Bore SDS Max Rotary Hammer Bit.

I know this is 1-1/8inch - and I'm assuming that means max of 1-1/8 in bit size. Just want to be sure.

Thanks.

Answer: 
1-1/8 is the recommended drill size, but you can fit a larger hole coring bit.
The SDS is a universal chuck from smaller to larger units. The 1-1/8 is the recommended largest drill size.
if you look at different size bits the chuck end is always the same.
there are SDS, SDS plus, SDS MAX and Spline drive.
SDS bits will work in SDS plus
SDS max is larger and not interchangeable.

Answer: 
According to the owner manual, the rated capacity is 1-1/8" with a solid bit, and 3-1/4" with a thin-wall core bit. You are correct in that the chuck size of a rotary hammer dictates it's maximum solid bit capacity.

Answer: 
Thank you for your question. The Bosch RH328VC will not accept the HC5091 bit, this model accepts SDS Plus shank bits will drill up to a maximum 1-1/8" diameter hole. To use the HC5091 bit, we offer the 11264EVS that can drill up to 1-5/8" diameter and 11263EVS that can drill up to a 1-3/4" diameter hole into concrete.

Answer: 
this drill will be too long if you can only have 9" including the drill and bit. I believe the drill itself is over 9". If you want to go a little larger this is a nice unit for its size.

The RH328VC is designed for drilling into concrete. If you are using one of our SDS-Plus bits those are designed for drilling into concrete so they would not work well for wood. For drilling into wood you would need the optional 3 jawed chuck adapter 1618571014. This adapter converts an SDS-Plus hammer drill into a regular drill for drilling into wood and metal. Read More

Answer: 
It does have a rotation-only mode, so you could. You would need either the Bosch 3-jaw chuck that is an optional accessory for this rotary hammer, or some other form of chuck adapter with an sds-plus shank.

Rated 4.6 out of 5 by 13 reviewers.
Rated 4.0 out of 5.0 by Bosch Like this rotary hammer, very easy to handle and powerful. August 9, 2016
Rated 5.0 out of 5.0 by Thor Can Have His Hammer – I Have This Hammer Drill This is one of the best tools I have ever gotten. And I am not exaggerating one bit. I recently completely a project where I put down a sand based patio in my backyard which is fenced in. In order to put down the track for the pavers to sit in, I had to get rid of concrete that my fence posts were planted in for stability. I took out this hammer drill, bought a SDS chisel bit, and went to work. First off, the hammer drill comes in its own carrying case which is really nice and convenient. Setup and usability was a breeze. I read through the instructions but basically just inserted the SDS bit in directly, hooked it up to power, and started going through each setting to get a feel for it. It has multiple settings of operation, from drilling alone, hammering alone, and drilling and hammering together. It also has rotation feature to get the chisel in the correct axis for you. And it has a forward and reverse spinning gear to switch over to. This hammer drill went through the concrete posts like it was nothing. It literally just pummeled the concrete into pieces. It was almost effortless. It was so effective that I drilled out extra concrete just for fun. Nothing slowed the hammer drill down – it was fantastic. The tool isn’t overly heavy and feels like it is built to last. It’s not too noisy and is plenty powerful. So powerful in fact that I actually got the bit stuck when I went too deep into one of the concrete blocks. This was not the tool’s fault – it was my own user error since I chiseled in too deep and actually got it lodged in the wood base of my fence. The special vibration handle dampens a lot of the harsh vibration so you can continue to use the tool for awhile. It does require a SDS bit, but if you feel the need you can buy a 3 jaw chuck for it so it can be a little more versatile. Again, what a great tool. The true testament to this tool is that my father, who isn’t usually a fan of “fancy” new technological tools, absolutely loved it. He continued to praise it and said it was the most impressive tool we bought for the entire patio project (and we bought many, many good tools). Well done, Bosch. July 26, 2015
Rated 5.0 out of 5.0 by Rotary Hammer Has Good Ergonomics, Anti-Vibration and Power If you are in the market for a mid-sized rotary hammer, look no further than the Bosch SDS-Plus 1 1/8 Inch Rotary Hammer, Model RH328VC. The first thing I noticed is how well balanced the tool feels and easy to use. At 7.7 lbs and 14.5 inches wide, along with a very effective anti-vibration system, it’s designed for all day use. I am very impressed with the tools ergonomics, features and performance. The Bosch RH328VC Rotary Hammer has a powerful 8 amp variable speed motor, delivering 0-900 rpm, 0-4,000 bpm, and 2.6 ft-lbs of impact energy. It has a capacity of 1 1/8” hammer drill bit and 3” concrete hole saw. The RH328VC includes an all metal gear case and mechanical clutch to protect the motor in case the bit binds. It includes three modes of operation: rotation only, hammering, and drilling and hammering. It also has a mode for accurately adjusting a chisel style bit when hammering. A side handle is also included which has an integral depth adjustment rod. It took only a few seconds to drill 3/8” holes through 4 inches of concrete. Overall, I am very pleased with the Bosch 1 1/8” Rotary Hammer. It’s small enough to be very comfortable performing small jobs, yet large enough to perform the vast majority of tasks most users will ever encounter. May 30, 2015
Rated 5.0 out of 5.0 by THIS DRILL ROCKS! AWESOME! 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 in (concrete?), 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). I've also drilled and split a number of foundation stones in front of my barn so that I could cozy a large granite landing up to the sill. . Those were difficult to split, but each hole only took about 30 seconds to drill. I bought a longer carbide drill for future rock work. Let me assure you that this drill and a 1/2" carbide bit will drill a four 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). 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 think bit price and availability should play a big role in your decision of chuck, though. July 26, 2013
Rated 5.0 out of 5.0 by Superb (relatively) quiet hammer drill The excellent little piece of machinery is easy to use. It's very quiet (well, as hammer drills go...). Truly. Quite easy to install the bits The shock absorbers work really well. This hammer drill does NOT vibrate your hands off. We used the hammer drill to drill holes in brick to install anchors for a porch roof and kitchen cabinets. We used it on a large block of slate for anchoring a piller. September 8, 2015
Rated 5.0 out of 5.0 by Great product Great drill and works as expected. Used it only one time so far and drilled holes in block wall like cutting through butter September 8, 2015
Rated 5.0 out of 5.0 by Works like a charm Powerful and yet feels comfortable to the grip, this rotary hammer works like a charm. The usual Bosch quality I can trust. I expect many years of good service from this Bosch rotary hammer. July 14, 2015
Rated 5.0 out of 5.0 by Work Smart With The 1-1/8 Inch SDS-Plus Drop Down Rotary Hammer Drill. As the old saying goes, you can work hard, or work smart! I've been re-tiling my house, and was killing myself with the old fashioned hand scraper to remove old tile that were really stuck in place. I got this Bosch 1-1/8 Inch SDS-Plus Drop Down Rotary Hammer Drill Model RH328VC and my life just got a lot easier! Paired up with the Bosch Tile Chisel, this beast tears up tile like nothing I have ever used before! Bosch makes a whole bunch of other SDS-Plus accessories that I now look forward to trying out, including the Bosch 1618571014 SDS-plus Shank 3 Jaw Chuck so I can use my regular drill bits in this drill. I really love the extra large trigger on this hammer drill, and the simple to use controls. The depth gauge was a nice addition to it as well. Even the carrying case is well-built and has enough room to store extra bits. All in all, I love this beautiful beast! Thanks Bosch, and Home Depot! May 29, 2015
