Title: Dull bits of poor quality materials
Review: I needed a drill bit set offering a large range of sizes. The Pro-Tech Ultimate offered a huge range of sizes with drills made for wood and metal. I have used seven different metal bits and have not been able to create a hole - even through a metal stud. Four of the bits broke with their first use. The case is nice, and the screwdrivers and nut spinners seem OK. I was hopeful that this would be a wonderful set to drill bits turned out to be fairly worthless.
