This one worked much better. I only used it 4 times to cut holes for radiator pipes coming up through the floor, but it cut holes much easier than my old, blunt bits, and still looks in good shape. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good value, worked well. *by G***D on Reviewed in the United Kingdom on 30 November 2023* Worked well, did the Job I wanted it to. Cut through wall tiles with no problems ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Does the job well! *by P***T on Reviewed in the United Kingdom on 28 December 2023* Used to drill hole in bathroom tile during fitting of new toilet.
