large bore forstner bit (1 3/8) had difficulty with treated 6 x 6 post

Bough these last minute to finish a quick project. Never owned these types of bits before and have wanted to buy a set for awhile. So glad I chose these. They are in a very good case that fits great in my toolbox and so far are great quality.

Garbage. They are not sharp; doesn’t drill through wood or plastic. I’m not even sure if it can drill through butter.

I like the set.My only caveat is after inserting the bit into the drill tighten the chuck as tight as possible because the shaft of the bit that inserts into the drill is smooth and cylindrical- so it will slip when resistance is applied as you bore. Most other accessories intended to be inserted into a drill, the shaft has a hexagon shape so the drill can hold it in place as resistance is applied during bore.

Bought these 11/10/23 to anchor a dowel for a newel post for building stairs.I bought the 6" extension too for a deep hole. Unfortunately, not all of the bits are 3/8" shank as advertised.The 1-1/2" bit is larger. Did not check them all but smaller ones do fit the extension. I have not measured it yet but I estimate it to be about 10mm. .393" instead of .375".

Very poor quality. Burrs, chips and/or dull edges on most cutting surfaces of all five bits. Promptly returned for credit. The old adage applies: you get what you pay for.

They work, but not great
