Mon, 22 November 2004 22:44 If you're going to use an easy out, use the biggest one that will fit inside the broken bolts basic minor diameter with about .5mm of clearance. Always be wary of drill speeds when drilling hard steels (light alloy you can get away with huge speeds but the same on steel will overheat and snap bits). Some recomended speeds (from my black book) are as follows - 5mm bit in tough steel, 700rpm - 6mm bit in tough steel, 580 rpm - 8 mm bit in tough steel, 430rpm, and always use lubricant, try to have an assistant (or apprentice) spray kerosene/wd40 onto the drill bit. Always remember to back off the drill after a couple of seconds of force, not entirely out of the hole just releive some pressure to clear the flutes and to let the bit cool down. Also try not to force the drill to take excessive cuts Finally, nuts and bolts you know will be easily snapped, i.e manifold studs, bath in crc a day before you're going to try to remove them, oxy is rough and i've never had much success getting it to work on bolts that are already exposed to 'heat up/cooldown' situations. Sorry for the lecture, i just get sick of people breaking my drill bits at work EDIT : and punch the hole first... very important [Updated on: Mon, 22 November 2004 22:45] [Report message to a moderator]
