Good quality bits. A bit expensive but worth it. Quite useful in DIY stuffs. Material quality is good.

I needed either a step drill bit or a reamer drill bit in order to widen some holes in my squat rack. My squat rack has 1/2" holes and I needed to widen a couple of the holes to 1/2" in order to fit a pair of jammer bars. These drill bits worked exactly as I had hoped. The drill bits are very good quality. I had no problems using them with my electric (corded) drill. The bits cut through the steel of my squat rack easily. The included storage case with the drill bits is definitely a bonus. For me, this kit is a buy once purchase that I will always keep.

> Great set of step bits for the price. Cuts clean and smooth through metal without grabbing, and the size markings are easy to read. The range of sizes is really useful for different projects. Held up well so far and stayed sharp. Nice set to have in the toolbox—would buy again.
