BOSCH HS1911 SDS-max hammer Steel 12-In Flat Chisel, Gray

Holy cow this thing is awesome!our old one: We purchased a smaller version at HD for $20 last year when we had to remove a 5x8 space of tile for a pantry. My husband's back was killing him from bending over in practically a hunched kneel and the project took him 3 days of backbreaking labor. And it made so much dust! the cement glue stuff didn't come off at all and the cement was left uneven with many dings left in it. It was horrible. The blade was more like a dull thick piece of metal and the handle was only about 5 inches.The new one: We used the 6x12 inch scraper that we bought from amazon the day we received it. We had to remove 6 1 foot tiles to expand our kitchen cabinets. I half way expected the tile scraper to be as big as a pain and mess as our previous one, but thankfully, I was wrong. In about 10 minutes or less me husband was done. The tile pieces came out with no real effort and the "tile grout glue" was easily removed and the cement was left smooth. My husband was so thrilled that he removed even more tiles, mainly to see how long it would take to do a 5x8 space as to compare to our previous experience. He was done in less than 20 minutes with the whole project, and his back didn't hurt at all! It is wonderful that the blade part is sharper and wider, leaves a cleaner "cut" on the cement. The handle is very long as well so you do not have to bend over awkwardly. There was little dust as well because the pieces came off in pieces and not dusty shards.We plan to redo our tile in the next few months, and I was worried that the project would make living in our home unbearable based off of the first tile removing experience that we had- we were planning on at least 1 month just removing the tile and dust everywhere; I was considering temporarily moving in with my parents while my husband worked on the project! Now with our new tool, however, I know that the project wont be so horrible and the removing process will be greatly reduced.Thank you for making such an wonderful product.

This is the smaller, SDS Max version of the Bosch HS2861 start pointed chisel bit (the HS2861 has the full-breaker sized 1 1/8" shaft and self-sharpening tip").The photo Amazon is using is not the correct photo. Search for the HS 2861. This one, the HS1934, looks very similar the HS2861. Apparently this chisel is somewhat difficult to find, as two very large tool stores in my area (both big Bosch distributors) did not have it in stock, and would have had to order it.This chisel works very well, driving itself through concrete noticeably faster than the HS1904 bullpoint chisel. BUT, I found that when driving through a compacted / compressed area (for example, breaking up an old fence post footing in the ground), this bit got stuck much more quickly and frequently than the bull point. It almost drives itself in and gets stuck too fast. Unless you are careful to pull it up frequently and before allowing it to drive itself in and wedge itself stuck (which I found myself doing more often than with the bull point chisel), you will be wrestling with the hammer (I have the Bosch 11245EVS) to get it unstuck. Having to hold back from allowing the bit to drive itself deep into the concrete, and being more diligent to chip away at the edges to break off smaller pieces, versus in the middle to get larger pieces to break off (in a narrow, confined space, as in an 18" diameter, 2 ft deep hole, where there is consistent, constant pressure on the material, as there is no where for it to "break off", or fall away) was more tiring than it was using the bull point.The lack of market displays, advertising (it only gets a line item mention in the Bosch catalog), availability, etc, vs the spiral self-sharpening version, model HS1936, suggests that Bosch would prefer you buy that model. Perhaps it has less of a penchant for getting stuck. I have one on its way, and will post a follow-up when I try that chisel.For breaking at the edges of a slab / pad (where the pieces will have more room to fall away and separate), this chisel works very well and noticeably quicker than the bull point.

Turn your SDS-MAX rotary hammer into a power shovel.This thing is solid. And does great in cutting through clay.If you need to dig quickly — this will do it.Wish the shank was longer.

I used this bit in a power hammer to dig a trench around the inside of my hose footer. All clay and rock digging. It held up fine, and made the job way easier than digging by hand.

I use this to dig a 30 inch trench 15 foot long for underground piping and it was all rock. I never changedthe bit because you can use it as a chisel can use it to pry and dig. It’s still like new Well worth the money don’t even consider other brands.

I have clay soil with lots of rocks. Trying to dig with a regular shovel is near impossible. When I attached this to my roto-hammer drill, I was able to dig multiple holes for planting fruit trees. I also used it to dig a sump pit for a French drain. It works well in the conditions and it hasn't worn down yet. I've been using it for 6 months and it shows no wear.

Good price for quality name brand.

I had to dig a trench 120 feet and in some places it was over 5 ft deep and I began to hit boulders.I called a local and asked him if a skid steer and a jack attachment would break them up.I was told, you have to dig them out, it would be a waste of time to try and break them up.Challenge accepted.I used the a Bosch RH540M 1-9/16 Inch SDS-Max Combination Rotary Hammer with 5/8 inch and 3/4 Hammer Bit drilled into the boulders and then I split them with some 3/4 Feather and Wedges, those thing are amazing.I also used the Bosch Clay Spade and Chisel Set on the impacted clay.It took about two weeks and it was a lot of work but the drill, bits and spade never let me down and I got the job done and saved a bunch of money not hiring someone with heavy equipment to remove the stones.
