A great addition to any tool box. Excellent quality at a very good price point.

Highly recommend.

I work with appliances and appliance replacement- this item I use when I have to manually thread a random length of black iron. Slap it on my drill to quickly ream our black iron. It works well- the hard black iron hasn’t worn it down and I’ve used it for several jobs now. Knowing how it’s standing up to black iron, this bit would be a beast on straight tin especially considering the price. Has a nice little plastic case it comes with too so can be chucked right into the threading bin or tool box.

Nice quality. I night this to go with the other 3 piece kit that they sell. I’m really happy. Nice and strong. Perfect for electrical work. I’m quite happy.

This is by far the toughest, most durable and best step drill bit I have ever tried. I'm sold. Nothing but these from now on. ... AWESOME!

I needed to enlarge a 0.75 hole to 0.875, but the catch was that it was cutting thru 0.75 thick mild steel on a backhoe. I really thought this bit would just snap.. but it powered thru the task with ease. Two holes completed and just as sharp as new. Thank you, Vevor!

The bits are really good, was able to tap 12 5/8 holes with one of theses bits. It did slow down quite a bit after the fourth hole even with cutting fluid, however for the price they work better than expected

Worked one time only

Great

So far so good
