Rated 5 out of 5 by from Quick Change, quick job! These are the best holesaws I’ve used. Even cuts through stainless no problem. Long lasting when used in conjunction with cutting lubricant. Quick change arbour saves lots of time when using different sizes. Highly recommended.

Rated 4 out of 5 by from Good at cutting cast iron soil Bought this hole saw and Bosch arbor to cut a 57mm hole in a cast iron soil pipe. It did a good job and cut a clean hole.

Rated 5 out of 5 by from Best on the market Great for cutting thin stainless steel. Just need to make sure that you set combi drill to slowest possible setting to make an accurate cut.

Will this go through cast iron downpipe?

I need to attach a mcalpine mechanical boss connector 40mm to a cast iron downpipe and need a holesaw to do the job.

Does this need the 7.15mm(737HF) or the 8.7mm (737HF) arbour?

Does this need the 7.15mm(737HF) or the 8.7mm (737HF) or ¼" (606KR) arbour from Bosch? Or will they all work fine?
Asked by: uniplumber
Hi Uniplumber. The 7.15mm and 8.7mm both refer to the shank size. The Holesaw will fit on both of them. Thanks, Bosch.

What size bit/arbour

What size arbour does this holesaw require?
Asked by: PBateman
Hi PBateman, all of our arbors are compatible with this holesaw. The only difference between them is in the shank size. Thanks, Bosch.

Hi will this go through cast iron?

Asked by: Mick1982
Hi Mick1982, this is largely dependent on the thickness of the cast iron you wish to cut. Thanks, Bosch.
