E1195 You are buying an 18 drill bit set in the padded nylon case with hook and loop closure. 2-1/4" bits, 2- 3/8" plus 
one each of the following : 5/16, 1/2 , 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, 1, 1 1/8, 1 1/4, 1 3/8, 1 1/2 "

LOOK CLOSELY AT THE PHOTOS.  13/16" BIT WAS USED, I see no evidence that any of the other bits have been used.

These bits are very aggressive with the screw tip, they really grab hard. I'm a retired contractor and have used these in the past.
The holes they make can be rough as a result. These are " boring" bits generally used in rough frames etc.Get it done quickly

Nice case with elastic and sleeves to securely hold the bits. Be safe and enjoy your work.
