What people don’t love

  • Some users found bits brittle and prone to breaking under harsh conditions.
  • The included case has design flaws, including a wonky latch and non-folding indexes.

Highly recommended heavy-duty drill bit set with excellent cutting performance though a bit fragile and comes in a less-than-ideal case.
