Customers are mixed about the durability of the drill bits. Some mention that it has held up really well, while others say that it isn't super durable, the titanium isn’t strong enough, and the center punch broke on the third use. The metal isn t of the highest quality and they dull somewhat quickly when cutting steel, and it wore out after cutting four holes in a very thin sheet steel.

"...'s definitely worth it and then I've had it a month or it's held up great with daily use. I've used it on up to 3/16 steel, iron" Read more

Customers are mixed about the drill. Some mention that it did drill very well up until the 11/16 step, while others say that it would not drill mild steel at all, is great for drilling thru most metals, and is fantastic for drilling bolt holes in galvanized steel posts that they're using to hang sun. However, some say that the drill clearly states that it cannot be used on steel and that it will not cut through metal thicker than aluminum foil.

"Delivery good, fit drill well and drilled the hole required. Cannot attest to longevity or durability. It worked fine the one time I used it." Read more

"...last or how many holes I can cut with this bit, but it handled the electrical box hole easily and the bit appears unfazed." Read more

96 customers mention46 positive50 negative

Customers are mixed about the sharpness of the drill bits. Some mention that they are very sharp and precise, while others say that they lost their sharpness within the first 10 minutes of use. The case it comes in keeps them sharp longer, but some customers say that the drill settings lost their edge after a couple of uses. They expected better, and the machining on larger diameter edges isn't at all that crisp.

"The sharpness could be much better, but it got the job done that I needed it for. Be prepared to be drilling for a while though!!..." Read more

"...So a hole saw would not work. This cut a 2" 5/8 hole like butter. Very sharp and no heat marks." Read more

"Two of the step bits went dull in nothing flat. I have bought others that have lasted a lot longer than this set. Not impressed" Read more

"...It's clearly not a brand new set. The gold finish is dull and has marks on it. But I'll give it a try next week to see if it does the job!" Read more

Great on thin sheet metal, 1/8” not so much
4 Stars
Great on thin sheet metal, 1/8” not so much
I bought this to drill a 1-1/8” hole in 1/8” inch steel. The description says it will drill up to .20 material. It worked but left a hole with tapered edges, not a 1-1/8” hole all the way through, it left a smaller hole on the backside. Luckily I was able to drill the hole from the backside to make a uniform hole. It enlarged the hole gradually rather than in steps. I think it would be okay for drilling holes in thin sheet metal, but not so great in thicker metal

Reviewed in Canada on February 25, 2023
Wasn’t sure with this being so large how well it would work, but in my Dewalt 20V drill, it went through metal as intended.. the drill did struggle a bit, and watch you don’t break a wrist when it catches the metal, but I managed to get a hole drilled right to the largest size.. 2 3/8”
Not sure I will ever have a use for this large of a hole in metal again, but this did the job for what I needed it to!
