I'm looking for detailed pricing information on your Impact Driver Bits Set. Could you please provide me with your latest pricing for different quantity ranges? Additionally, I'd like to know if there are any discounts available for bulk orders or if you're running any promotions that might apply. Also, it would be helpful to get an overview of the features and specifications of the bits included in the set. I'm particularly interested in the materials used and any compatibility options with various impact drivers. If you have a catalog or any additional information, please send that along as well!
