Erbauer Bi-Metal Holesaw 51mm is rated 4.8 out of 5 by 15.
Rated 5 out of 5 by from Cuts through hardwood I bought this cutter to drill a 51mm hole through hardwoods maple and cherry. I set the cutter up in my drill press and made the cut halfway through from each side. It produced a perfectly smooth hole - I was well pleased. I have to use the cutter on several occasions over the coming weeks so I'll get an idea of its durability. I nearly bought the cutter though without the arbor which is vital to the set up. I only learned that I needed the arbor through one of the Q&As.

Rated 5 out of 5 by from Holesaw Bought this to fit five privacy locks to oak laminated interior doors. Made light work of job, as sharp and efficient on last lock as with the first. Good quality and good value for money.

Rated 4 out of 5 by from The saw, the hole saw and..... Its a hole saw, what can I say? I bought this hole saw to cut one hole so I wasn’t prepared to pay a lot of money. No one else in the area had one of the same size cheaper so I bought this one. I would say that it’s as good as Starrett.

Rated 5 out of 5 by from Cutting Guess what, it does what it was bought for, have only used to cut holes in soil piping but works great

Rated 5 out of 5 by from A cut above This inexpensive hole saw fitted my existing arbor, it even fits inside another cut in the box, so it won't get lost. It does what it's supposed to very well.

Rated 5 out of 5 by from Half the price of Drews! If you don't have it already - you have to use an... Erbauer 11mm Holesaw Arbor 32-152mm (1779H). With this - it works great! Without it - It won't work at all.

Rated 5 out of 5 by from Super cutter (Holesaw) Needed this - along with the auger - as I had to replace two shelvings on my fountain, both of which required an accurate circular whole cut. This did the job VERY EASILY and accurately - especially considering that D.I.Y. is not my forte!!
