This is a great set to keep around the house for small everyday tasks. As long as they work well. I am very happy with the set and loved that they came in a handy storage box.

Only 9 bits out of 13 have a hex shank

I haven't had a chance to use any drill bits so I won't rate their durability or price. But what I think deserves credit is the set's promotional literature. This is incorrect. The ad states that all bits have a hexagonal (triangular) shank. Not so with my set. Only 9 out of 13 bits came with the advertised hex shank; The other four bits came with traditional round shanks.

Pros
  • Twist drill bit
Cons
  • So far so good
