The 43-piece set with Extra Hard screwdriver bits and nutsetters is a good choice for general tasks. Screwdriver bits made of S2-modified steel, manufactured in an optimised heat treatment process, offer above-average hardness for high performance with all kinds of tasks. The conical torsion zone of the bits handles torque peaks well, as it absorbs forces and vibrations during use. In addition, the bits are colour-coded for a quick overview and identification of the correct bit type. It has a 1/4 inch external hex shank for general tasks involving screwdrivers and drill drivers.

The 43-piece set with Extra Hard screwdriver bits and nutsetters comes in a practical and robust storage box that offers both a good overview as well as safe storage and transport.

    Fantastic kit, been using mine for several years
    One review mentions the bits fall out, this definitely isn't true, they are kept secure in the case & have never fallen out.
    Also not sure if it's impact rated, but use mine exclusively with impact driver without issue.
    The 3 sockets are really handy too, especially the 10mm 👌
    Next price up on Amazon is £30
    Have some heat op 🔥

    73 percent discount from Amazon is misleading

    1 I wish they would quantify extra hard, using a HRC scale, or whatever is appropriate. Most of these bits from various manufacturers claim to be S2 steel, so if paying a premium, I want to know how this is better.

    2 The typical Bosch bits on Screwfix get similar customer review scores to other brands.

    3 There are cheaper bit sets at Screwfix, but I think this Bosch set could be good value if you need all the sizes in the box. Screwfix have something almost identical in a slightly different box for £32.99.

    Some of the images on Amazon show these are poor quality.

    More bits ordered... sually i get dewalt but these look good. they'll be great in an impact driver.

    Generally good reviews but seem to be some saying these are quite soft and break/round off quite easily. I don't need this set, but still want it . Anyone else used it with negative experience?

    Just delivered, better presented than a box of chocs. Am off to the garage for a play.

    Good price, they do seem to have changed the build quality of the storage case, I have 2 other similar sets and the clasp is spring loaded, and the black is more rubberised, here it’s hard plastic and a sliding clasp. Heat op

    You can have metal that is very hard but it can also be brittle. It seems that this set has not got the right ratio of hardness and toughness.
