    Nice set
    So far, they are very nice — cuts easily, nice package — time will ultimately tell, because durability is paramount.

    Good price, good product
    Pretty decent set of counter sinks. Price is good and the quality was good, I have only used one so far. It chattered pretty good, turned the speed up slowed my plunge and all is good so far.

    Counter sink bits.
    Had to correct the pre drilled holes in steel door magnet mounting plates. Arrived as promised and they are of good quality. Would recommend.

    Cuts steel
    I just finished countersinking ten 3/8 holes in a piece of hot rolled steel. The bit cut just fine & did not seem to get dull during the process. The tenth hole cut just as easily as the first hole. The little storage box is nice also.

    Nice looking tool, and nice storage case.
    Tools look nice and have a good case. Unlike some others that do not have a case these will not get lost nearly as easy as a preventive set I had, that set didn’t have a case.I haven’t used them yet so u cant say how well they will hold up. They look like they are well made.I will update this after I have used them.Thank you.

    Counter sinks
    Not very good. Only good for wood or soft material. Not what O expected.

    Aunqie son de cobalto (supuestamente) y cortan relativamente ràpido, el afilado es bastante deficiente, en definitiva es necesario usar otro avellanador de HSS para darle acabado final.

    I’ve used this a few times now on aluminium and phenolic, and it worked fine. They cut clean, and I like the size variety. I particularly like the long shank on the smaller countersinks, which is handy for doing a quick deburr of small holes by hand.

    Looks very strong and good price, using on stainless steel. Recommend the cobalt set, M35

    Did a good job on stainless steel which had been chewing up standard HSS countersinks. Giving the full 5 stars because it did much better than I expected, to be honest.

    Juste bon pour fraiser du bois mou. Ce n’est surement pas du M35. La 3/4 glisse sur l’acier doux.
