Review on Bosch HS1922 Spade SDS Max Shank by Muleme Bollinger

I purchased this tool for use with Bauer 11 Amp 1-9/16 In. Harbor Freight's SDS Max-Type Pro variable speed rock drill is digging in a slope in our yard for a retaining wall. This is perhaps the best accessory I've bought to use with a jackhammer. It does well in mud and clay and has a hard time working with mulch in wet/wet areas, but that's probably the case with all clay shovels. After drilling 180 linear feet in our area at a depth of 12-18 inches, the drill has very few defects. Was able to cut through hidden bricks and tree roots up to 1-1.25 inches in diameter. Larger tree roots required a saber saw. Given the terrain and what I found underground, I expected the clay shovel's leading edge to be more damaged. but Bosch did a great job with this attachment. I would recommend everyone to have it on hand. I've read that people have successfully used a similar fast hole digging device to plant new trees, bushes and dig stake holes. very happy buyer.
