Bosch Progressor Cobalt Holesaw 57mm is rated 4.2 out of 5 by 6.
Rated 5 out of 5 by from Quality Holesaw After being told by various plumbers that it couldn't be done I bought this to put a hole in an existing cast iron stack to add a new downstairs saniflow. They all said I'd be wasting my time trying to put a hole in cast iron as I'd just burn out the bit and would have to change the stack for plastic. Well I went with my gut and with the aid of a little cutting compound this Bosch holesaw went through it like butter! Highly recommended!

Rated 4 out of 5 by from Great product Cut a 57mm hole in a cast iron soil pipe which the Erbauer would hardly scratch

Rated 4 out of 5 by from Cast iron soil stack Started using Erbauer Holesaw from a set I already had to install Mcalpine connector boss into old cast iron soil stack. The tool dulled almost straight away. Bought this and completed the job relatively quickly with the tool still fit for further use. Also much quicker to fit or exchange to the powerchange arbor than the Erbauer. Definitely worth the extra money. Wish I had found these first.

Rated 2 out of 5 by from No good for stainless Bought Bosch as always been very happy with their products. Specs says will cut through stainless, it doesn't !. Got it specifically to cut some 1mm stainless all it did was loose its teeth and deform the metal. Maybe good for other materials but a let down with stainless.
