The auto start tip was a great asset and made the hole right on the mark.

You need this mandrel to help turn the bit and it is a pairing. You must have both. It works very well in your drill with both parts, the correct size bit and this mandrel.

Great product !!. First time user. Drilled one 4 1/8 ” inch hole threw 3/8″ marble for shower faucet. This auto start bit made the task very easy. I did do a practice hole on a scrap piece of to familiarize etc.

Works well wet with spray bottle.

I bought this last week with a 4-1/8 inch diamond hole saw to cut a new hole for a toilet. The Anvil and hole saw took over an hour to cut hardened 80 year old concrete with a large gravel component. The plumber really liked this tool in comparison to other tools.

it worked flawlessly
Annabel Mraz (verified owner) –
Well made and reliable product. Clearer instructions on how this mandrel interfaces with the Hole Saw would have been helpful ;; I needed to figure it out through viewing several YouTube instructional videos.
Einar Ryan (verified owner) –
The mandrel was very easy to assemble and use.
Jakayla Ankunding (verified owner) –
Worked well
Nellie Tillman (verified owner) –
Used on very hard, slick, thick tile while using a spray bottle with water and it went right through. I was very surprised and happy how well it worked.
Marcia Stiedemann (verified owner) –
Great system, well built and precise
Gerry Gottlieb (verified owner) –
The hole saw cut through tile easily. The pilot would not bite into the tile surface and slipped. I had to use another drill bit to make a pilot hole for the pilot.
