## Description

This product uses an SDS-max shank to ensure tight grip for the toughest jobs. desertcart.com The Bosch HS1911 1-inch by 12-inch flat chisel SDS-Max rotary hammer bit is durable and ready for extreme performance. It uses an SDS-Max shank to ensure tight grip for the toughest jobs. Bosch brings constant innovation to concrete and masonry drilling. From inventing the industry standard SDS system to custom-manufactured carbide and diffusion bonding, the result is better performance and durability.

Review: Excellent chisel - 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 desertcart 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.
Review: So much better than the HD $20 version! - 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 desertcart 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.

### ⭐⭐⭐⭐⭐ Great accessory for dirt and clay... will tackle tree roots too.
*by D***F on August 30, 2020*

I bought this attachment to be used with the Bauer 11 Amp 1-9/16 In. SDS Max-Type Pro Variable Speed Rotary Hammer from Harbor Freight while digging back a slope in our yard to build a retaining wall. This may be the best accessory I have purchased to be used with a demolition hammer. It powers well through dirt and clay, it does struggle in wet/damp mulch areas but this would probably apply to all clay spades. After cutting 180' linear feet across our lot at a depth of 12-18 inches the bit has very few imperfections. Was able to cut through hidden bricks and tree roots upto 1 - 1.25" in diameter. Larger tree roots did require a reciprocating saw. Given the terrain and what I encountered below ground i was expected the leading edge of the clay spade to be more damaged but Bosch has done a great job with this bit. Would recommend for everyone to have on hand. I've read people having success using a similar setup to quickly dig holes to plant new trees, shrubs and excavate for post holes. I'm a very happy buyer.
