Product does the job for which it is designed
Good product and good "bang for the buck." More expensive items may be more durable for someone who uses them often, but for the DYI home shop, these do a good job.

Not durable
I used it once on metal L bars and it worked good for the first 5 holes but after that, it smoked and got dull. If you need something for professional use, this is not it.

Reasonably well made for the money
My set are extremely hard. They cut well enough but may chip the cutting edge

works fine on mild steel. No chatter in my mill.
I used these initially with a hand drill, got some chatter and overall poor finish. Chucked it up in my bridgeport though and cut some 1045 very smoothly and nice. No chatter, very nice finish.

Do what they’re designed for ..... and do it well.
Each item in this set came well machined and with perfectly straight shafts.I have used them on both steel and aluminum with good results. They leave a smooth finish that requires no additional “clean up” and none of the pieces shows any wear so far.I did not rate longevity and durability solely because I haven’t had the set long enough. That said the total lack of wear exhibited by the bits so far strongly suggests to me that durability and longevity are unlikely to be an issue. And, to be honest, given that they perform so well, at this price I’m really not concerned about longevity. (As long as they’re still available if I need to replace them of course!!!)P.S. No inducement received for this review.

Poor quality
Very poorly made, the cutting edges are all very dull and chipped/gouged.

Great Value for a Metal Countersink Set
I got the Countersink Drill Bit specifically to make countersinks is angle iron. The bits specifically state for metal and I was a little suspicious they may not work but for only $14 for a set of 6 it was worth the risk. I used the 16.5 mm to make counter sink for 1/4 screws. I was pleasantly surprised when I was able to drill 4 countersinks with reasonable effort to get the depth I needed. I used a battery powered 20V drill at a lower speed. The #14 flat head screw seated perfectly in the countersink.
