Erbauer Bi-Metal Holesaw 70mm is rated 4.0 out of 5 by 36.
Rated 5 out of 5 by from Good Value Holesaw bought because of diameter - 70mm and depth of cut - 38mm. Performed well installing 25 soffit downlights thru 18mm uPVC backed by 12mm exterior plywood. Some snags with offcuts trapped in the barrel requiring arbor removal to unclog, a minor issue that's common to other brands too. Pilot drill and arbor still in good shape and finished holes were smooth with minimal tearout. Great value compared to other brands

Rated 4 out of 5 by from Starrett compatible Needed 70mm hole saw to fit LPG gas inlet on motorhome, cut thro GRP no problem with no splintering or cracking of GRP. Have got a Starrett hole saw set but didn't have 70mm hole saw size, got this for a fraction of the price of a Starrett, it fits/compatible with the Starrett arbour also. Have only used this once so too early to compare with Starrett on quality and longevity but a great price.

Rated 1 out of 5 by from My Own Fault Was originally offered a Bosch branded model in store but was too mean to pay the price just to cut four holes. The assistant found this one for me which I bought. Don't know what it might be like in wood or metal but despite proceeding slowly and carefully cracking occurred adjacent to the cut in heavy gauge plastic. Should have known better, you get what you pay for.
