These high-speed steel (HSS) hole saw cutters drill clean holes for threaded fittings such as water butt taps. The 21mm cutter is described for 1/2" BSP male threads and the 34mm cutter for 1" BSP male threads, with a 27mm size in between.
The product details describe them as suitable for metal alloys, wood and plastic. Choose the cutter that matches the thread of the fitting you are installing.
