BOSCH HS1922 4-1/2 In. x 17 In. Clay Spade SDS-Max Hammer Steel Ideal for Digging Applications in General Gardening, Landscaping

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.
