I purchased this to install a deadbolt in one of the doors in our house. This bit cut through the wood like butter - a very clean and even circle. It cleared out most of the wood shavings very well. The bit itself feels well-made and strong enough that it will last a very long time.

I used this bit to drill holes in landscape timbers that I used to boarder my driveway. I drove old fence post in the holes to secure the timbers. I used over 50 timbers and at 2 holes per timber thats over 100 holes. The timbers are 2 1/2" thick i believe. It cut just as good on the last hole as it did the first. Just be sure to clear your chips every once in a while when drilling thick material.

Was a little concerned about buying a second hand forstner drill bit, but it was packaged in original wrappings, and worked like a charm. Considerably cheaper than buying a new one (almost 10 dollars). This was a one-use item for me to install a support for a weather station on my deck. My particular drill bit was from an Italian company, but made in China (of course).

Cuts a nice clean hole, I wanted a patio umbrella on the deck without a table, used this to drill a hole in a 2x6 with a single bolt through one end, attached to the top of the deck rail. I used this to drill a hole for the "umbrella" shaft on the other. The 2x6 just swings out for use, then back in when not needed, perfect for rain protection when grilling.

Good quality bit that drilled holes just like it's supposed to. Came in a nice little holder that's reusable to store the bit in if you so choose, and it also had metric bit dimensions on it. I drilled several pretty deep holes in hard maple with this bit, and it didn't even flinch.

This Forstner bit works well and makes clean cuts. It takes a while in my 8" Harbor Freight drill press. It's not as sharp as the same size Porter Cable bit, but for the price...it works very well.

Bit worked as expected. As with most of these bit the shaft was short for the purpose I needed, but since the chuck end is rounded was not easy to use and extension needed for deeper holes.
