Hiya

Been trying to drill my stupid cleat bolts out of my Winter shoes - I got one off OK but the other three seem to be made of some super metal that refuses to be drilled at all - so much so that it go so hot it started melting the rubber on the sole (I may have f**ked it totally not)

I'm using Bosch metal drill bit (as in a drill bit for metal) so wtf am i doing wrong?!

Cheers all

    drill slowly so you can still see the drill bit turning with medium pressure and use oil i you go full pelt youll just blunt the bit

    You might need a brand new drill bit. First bolt you drilled could possibly have knocked the edge off it. If you keep on trying to drill with a blunt bit you just end up hardening the bolt head.

    Bosch drill bits arent brilliant I got a set with my drill and they dont last replaced them with a set of Titanium coated High speed steel ones from Machine Mart much better.

    I see - got them now, no fingerprints left cos I ve burnt them all off, potentially ruined the shoes anyway (hopefully salvageable with some of those crank bros sole savers), probably ruined three bits....this is why I should nt be allowed tools!

    It appears that the best approach was to get them sertiously hot and then leave them to cool down - when I tried again, three of them unscrewed by themselves in the end

    LBS tomorrow to see if I ve ruined the shoes or not....?

    When drilling into hard metal I always remember what my old drylining tutor told me; "push hard, pull slowly".

    IE get your strong arm behind the drill but keep your finger light on the trigger.
