I use these as a mechanic working on heavy duty refuse trucks. These drill through steel fast with no problem. 10/10 recommend

Really good quality drills at a great price. I drill a lot of plastic, and most drills will spit plastic. Not this set. I even used them with a good lubricant to drill some spring steel sheets. Worked great and the drill is still sharp.One of my favorite drill sets now!

Great bits. They stay sharp and I believe they are the exact same set as the my Matco set for more than half the price!

Game changer!! I'm a heavy/ construction equipment field Tech. If I had to be stuck in the middle of nowhere (which I am, several times a week) with only one drill bit set and a serious deadline (it always is), THESE are the bits I'd want. Turns a 2hr job into 20 minutes tops. Never failed me and I've been abusing them for months now.

They work drill excellent time will tell how long they last but the step bit tip helps feed the drill bit through the material

Alright first off I haven't used them long term..but o my gosh they cut butter smooth. Beware- once you use these it'll be hard to go back to something else

I ordered these as an impulse Buy. I have a small shop and do Automotive fabrication. Most of my drill work is done from a press or a mill. In those cases I use centering start bits and step drill to the size required. However I was finding it cumbersome to use that same selection of step bits when working through chassis or body assembly. I've only used these bits a couple times but found them very adequate when using a hand drill and accurately starting holes from a center punch. So far I've only used the smaller size bits, saving myself the time and trouble of Step Drilling. These bits are far more then the I'm a little suspect of the larger diameter bits but to this point they have served their purpose very well.

Excellent bits for cutting through stainless steel. I just wish I could find a source for individual bits to replace the worn out commonly used ones.

Only used 1 bit once, but so far works well. Seems to be the company that Matco rebrands and sells for more than twice the price.
