albert fuller: Tested these drills on 1/4” mild steel in the drill press no pilot hole needed all but one drilled on size within .010” the 7/8” was utter crap one of the flanks had been ground wrong can’t be bothered to return them.

Aaron I: I paid $39 for this set.

In brief: If you do this a lot, or want to drill something harder than mild steel, or need a nice cut quality, get something better. If you only occasionally make holes, and don't care too much about how they look, then this set is a good choice.

I'm an amateur, but I have various drill bits all the way from harbor freight quality up to made in USA, machine shop quality cobalt bits, so I have some basis for comparison.

These bits fall on the harbor freight quality side of the scale, but at this price, what did you really expect.

What you get:

The bits are not very nice. You can see grinding errors on some of the bits by eye. They come covered in a sticky anti-corrosion substance that doesn't even come off with denatured alcohol, and each bit is wrapped in a weird cellophane wrapper. The case is pretty decent for a cheap set, but a long shot from a proper metal case.

How they perform:

I made 8 holes in 1/4" mild steel with one of the bits, for a total of 2" (with pre-drilling with a smaller bit). The bit survived without chips or damage and still cuts "like new" (which isn't that awesome for this bit, but it...

Ian: The reason for only 4 stars is I haven't used them much yet. I had no problem drilling a1" hole with a 3/16 pilot hole in 3/4" mild steel flat bar at around 200 RPM using lots of cutting oil. For my occasional use only needs which doesn't warrant spending $100's of dollars more for a professional grade set I am sure they will be just fine. Just make sure your drill press has the capacity and slow speeds required to handle the larger sized bits.

DGeweyDGewey: If I could go back in time.. and do it all over again.. would I buy these drill bits in the first place?

Well, of course I did! As a matter of fact, I bought 2 sets of them, which was really confusing because in the future, I ended up buying 2 sets of something that I didn't "yet" know that I already had!

Needless to say.. you'd be had pressed to find a better set of HSS split-point drill bits for the money.. anywhere.. except for right here at this very spot, about.. ohh.. 3 days ago, when I found myself pressing the "add to cart" button for a product that had already been shipped, and was already sitting on the bench in front of me! (Don't ask, it's part of the time traveling machinist paradox).

But that's niether here, nor there.. (Dad joke)

But getting right down to the quality of these bits, and why you'll want to own a set (or 3) of these for your small home shop.. let's start with why other Amazon users will tell you you shouldn't.

To speak to anyone who leaves a bad review of this product, you have unrealistic, and far-too-great expectations.. and hasn't your father ever taught you that, you get what you pay for, and you can't get...
