Are your screwdriver bits milled or forged? Most of the bits are forged for many reasons such as life, performance, prompt delivery and better production. Why is this important? The medium bits are recommended for driving standard (soft) screws and for impact use. Extra hard bits are suitable for driving heat-treated or case hardened screws, such as sheet metal or self-tapping and self-drilling screws.
The screwdriver bits are in the medium hard range and also provide additional flex as needed in some applications such as Torq-Set or Tri-Wing Bits. How do I determine if my bit failed due to being too hard or soft? In general soft bits will round while hard bits will shatter. Sometimes trial and error provides the best information.
