Review on High-Performance Metric Cobalt Twist Stainless Drill Set - 1.5mm to 6.5mm by Richard Jarvis

Bought these as a gift for my dad, he does a lot of DIY projects and loves tools, he mentioned the necessary bits made to go through stainless steel so I'm over them and those Stumbled upon reviews I thought they would be a great addition to his tool arsenal. After using them he told me one of them broke and it didn't affect the stainless steel he was trying to drill through. So sad that this happened and I looked like I bought him poor quality tools and now he's sticking with them. I hope to get her back
