I bought this HS1495 short chisel to use with a Bosch 11224VSR SDS rotary hammer. The chisel is decently made in Italy from high quality steel and has an overall length of 5-3/4 inches, but the length is further reduced to around 4 inches when inserted into a hammer, making it suitable for penetrating tight spaces is where a standard SDS chisel would be too long. Together with the Bosch SDS square adapter, the installation becomes even more compact. It seems to work just as well as any other SDS concrete pulverizing bit so I think it was a good buy.
