    One thing I like about the case made by Irwin is that it has a clear top that shows what's inside, the bits stay in place and the case closes and locks.


    I used a hand drill to work on stainless steel, but it didn't work very well, but I think it will work well for my application.


    A great set of countersink bits for various diameters. Came ready to use and will last a long time.


    They are very sharp and cut easily into basic steel, making them a good option for anyone who uses drill, electric or battery.


    These countersinks are made of a harder material than wood, so they can be used on soft metals, but they are not as hard as the ones made exclusively for wood.

    Question & Answers

    Q:

    I am wondering if anyone is having issues with slipping.

    A:

    I've had them for a while and they're still sharp, but I think the issue of slipping is more related to the quality of your drill.

    Q:

    Are they better off just buying disposable Harbor freight or will they age up and I'll have to buy more expensive ones?

    A:

    Personally I'd prefer using a different tool when working with stainless steel, they are HSS.

    Q:

    Is this a two step process compared to the quick-change 5-pc set?

    A:

    It's two steps, the first one is to drill a hole and the second is to countersink a spot for the screw head.

    Q:

    What is the difference between this set, set 1882076 sold at Lowes, and set 1877791?

    A:

    The difference between metal and wood is not as great as it used to be.

    Q:

    Is it good for 1/2 steel?

    A:

    I think these would work equally well on steel and aluminum, with the proper rpm, feed rate, and lubrication.
