Question: Whats the best spade bit for digging holes with this tool the Bosch 11240
Document: I purchased my last Roto-Hammer in 1977 and it was the best available. This Roto-Hammer cuts 1" holes in old concrete like my old one cuts 1/2" holes. Great tool.
I purchased this for home use and I love it. I've used it for holes, demo and digging. It is a flawless performer. I don't use it daily so I can tell you how it would hold up as a contractor tool.
I bought this to replace my older round hex style Bosch hammer so I would have a wider variety of SDS max bits to choose from. This particular tool is great for medium demo work or drilling holes for electrical or plumbing lines thru foundations. And it's Bosch so it should last forever
I am a serious DIY guy. My latest project required running 1 inch PVC conduit through 2 concrete walls. I purchased the Bosch 11240 SDS-max Combination hammer and a 1 3/8 inch Bosch SDS-max masonry bit. My 2 walls are 8 inch cinder block filled with concrete and one of the 2 walls also has a 3 1/2 inch brick veneer. I was able to penetrate both walls in approx 2 minutes and 3 minutes respectively.
On the product details of seller's description is written: Origin Germany. You must know that this item is made in China. I DONT SAY IS FAKE but i just wanted to mention that. My other bosch tools are made in Germany......anyway.This rotary hammer is very powerful and I believe is the best for its category (13-14 pounds).
I bought this Bosch to tear tile off of concrete floors. It will eat tile up and wear your arms out. I also wanted it to be large enough to demo small areas of concrete and hammer drill larger holes. I am expecting it to work well for this also. Over the years I have used Bosch hammer drills/chisels on the job and found them to be dependable tools.
I used this to drill through 8&#34; of concrete with a 2&#34; bit with no issues. It is very easy on the wrist unlike the older hitachi I have. It also works great as chipping hammer.
VERY, VERY  powerful. When it hogs in you can't hold it back. I use it to drill granite. It is a bit heavy for use in awkward locations. I probably should have chosen the next smaller model.
This is a must have for anyone that needs to remove mortar beds or drill holes in concrete. I never realized how many uses I would have for it until I bought it.
Bosch SDS Max works great!! I have had great out come with there hammer drills as long as they have been in the market.
