Frustrating for

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…

Fantastic drill set, much better than most

I bought these drills because I needed to refine my choice of metric units but didn't want to mess with one of the extremely expensive big brands. until I get a feel for which sizes I need more than others (replacing each as needed).

Pros
  • Great for a small home
Cons
  • Questionable purchase for seniors

Jobber drills are worth every penny

I bought these a few months ago partly because they're pretty expensive thinking they're the best for the job or they're going back to Revain. I didn't have to worry. I didn't think I'd need them for carbides, but I need a metric set because that's what I mostly work with. And when I realized that they are measured in millimeters and a half millimeters, I was impressed. This makes them better suited for English size screws, tap holes, through holes, etc. What I didn't expect is that they work…

Pros
  • Durable finish
Cons
  • Damaged
