    Some are made of poor metal.

    not all torx bolts are made of the same materials.....

    Same with Torx tools tbh, I've broken/worn more torx tools than allen keys.

    I find triple square bits easier to drive in than the next size torx.
    I've broken 4 torx bits on (car) disc retaining screws.* Difficult to get a Dremel in the right place to cut a decent slot so used to use a cold chisel but now just go straight for the drill, preferably my left-handed/reverse drill bits as they'll sometimes undo it in the process, but I've mislaid them.
    I assume the monkeys that car repair shops seem to get doing brake work think that the screws are the only thing holding the disc on, rather than the wheels.

    * having used heat and penetrating oil if it looks like they'll be a problem.

    It goes without saying that these footrest fitting will have a thread lock on them of some sort. Even a small amount of heat will release most of them, so a hairdryer would heat it up enough (eventually). You don't need to use a blowtorch but a decent heatgun is right up there in the top ten "tools to have" for a bike workshop.

    Further to this, pouring a kettle full of boiling water over it will be enough to weaken most thread lock compounds.

    How does that work ? I imagine some engine parts get hotter than 100c.

    Different grades of loctite for different applications. Jap bikes generally have white heat releasing compound on brake parts and footrests etc.

    This was in Aldi last week. Only a 12v one but may be powerful enough to cut your slots.

    If you access to a grinder and have a spare larger torx bit try grinding the bit to a taper that just fits but will grip when hammered in. That combined with rotating the fitting at the same time might undo it.

    These are one of best ever purchases. Tap them on with a hammer than turn and the harder you turn, the deeper they cut into the bolt and will move it. Seriously good bit of kit and everyone should have set.

    Remove the footrest hanger ( 2 bolts to left ) complete with heel then get someone to weld a nut onto the end of the bolt
    the heat will almost certainly free the stuck torx screw and you can get a spanner on the nut to turn it before it goes completely cold

    if that fails drill it out and helicoil while you have it off the bike
