Review: Excellent for pipe work through masonry - Needed these for a plumbing task. Excellent quality , they work really well. The drill bit can be used in a standard (non SDS) drill chuck. Have used them a couple of times now and remain very impressed
Review: Very sturdy and did the job - Very well packaged, put to gether well and worked a treat. Used on a slow speed and cut through brick like butter. Only secured with the lug screw so not sure what the bolt was for, but great value for money for the odd use. Not sure how it would be with constant use by a plumber
