Nick Garland Posted February 17, 2006 Report Share Posted February 17, 2006 Right I have an Adamant A1 frame with a steel bolt stuck in it. Its not your normal snap, its at an angle. I have taken it to garages and none will even attempt it as they think the drill will just slide due to the poisitioning of it. I have also taken it to a lawnmower shop and they snapepd 2 drill bits trying due to it just bouncing off. Anyone have any ideas of how to get this out?

Walleee Posted February 17, 2006 Report Share Posted February 17, 2006 (edited) Is that a hollow bolt or just where they have attempted drilling? Where about's on the frame is it?If it's hollow a rat tail file could help to seat the drill by chamfering the internal hole........

Nick Garland Posted February 17, 2006 Author Report Share Posted February 17, 2006 Its the top right magura mount, it isnt a hollow bolt thats just part the sheered off. Quote Link to comment Share on other sites More sharing options...
The enchanted broomstick Posted February 17, 2006 Report Share Posted February 17, 2006 Easy OutsRight im not sure if this is the proper name for them but i have always called them easy outs and a few other people i know. Basically its like a drill bit with a thread on it. You wack the drill in reverse mode with one of these bits in the end. The "easy out" will turn anti clockwise drilling into the remainder of the bolt, you will notice on the picture they are tapered as well. As the drill bit goes further in its threads lock tighter and tighter until VOILA your bolt unscrews.Tool 1: Drill with reverse modeTool 2: "Easy out"Tool 3: Safety specs (remember to stay safe!)stu Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted February 17, 2006 Author Report Share Posted February 17, 2006 Wouldnt they only work if it was a hole bolt? its like the threaded part of the bolt and abit of material. Quote Link to comment Share on other sites More sharing options...
dave33 Posted February 17, 2006 Report Share Posted February 17, 2006 the only way you will drill that is with an end mill not a drill bit so take it to and engineers they you will be able to screw a bolt extractor in to it Quote Link to comment Share on other sites More sharing options...
Synergy Posted February 17, 2006 Report Share Posted February 17, 2006 sorry if im wrong but could you not hit it with a chisel making a | mark then try and unscrue? or is it totally forced in? Quote Link to comment Share on other sites More sharing options...
downhill_rob2@hotmail.com Posted February 17, 2006 Report Share Posted February 17, 2006 file the top down, so its flat, then it will be easier to drill it... Quote Link to comment Share on other sites More sharing options...
the judge Posted February 17, 2006 Report Share Posted February 17, 2006 file the top down, so its flat, then it will be easier to drill it... Good call, that's what I did with mine and it made it loads easier to drill Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted February 17, 2006 Author Report Share Posted February 17, 2006 Well my dad and I have had a bash at it, we have half the bolt out. Snapped 2 more drill bits and blunted a 3rd, filing didnt work, chiseling didnt either didnt have a small enough chisel. My dad had the idea of grinding into it creating a small slot to remove the bolt.The way it will be fixed is by using a "fake" metal pouuring it in, it then bonds with the alu and they drill and re tap, would a small slot significantly weaken the mount at all? This is a back up option if drilling really doesnt work. Quote Link to comment Share on other sites More sharing options...

This is a back up option if drilling really doesnt work.That would probably work, however it would probably be quicker and easier to just helicoil the thread when you have drilled the bolt out (would be a stronger thread as well then) Edited February 17, 2006 by the judge Quote Link to comment Share on other sites More sharing options...
Al_Fel Posted February 17, 2006 Report Share Posted February 17, 2006 cut across it with a hack saw just chop into the frame a bit and get a smallish screwdriver on the go. thats my suggestion. Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted February 17, 2006 Author Report Share Posted February 17, 2006 lol if you saw the state of it after the diamond harden drilled has been at work I would like to see you try to helicoil it, its such an odd shape now. Ill post up when its done. Quote Link to comment Share on other sites More sharing options...
Jaffacakes Posted February 17, 2006 Report Share Posted February 17, 2006 Couldn't you just drill the bolt into the frame or aren't magura mounts hollow? Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted February 17, 2006 Author Report Share Posted February 17, 2006 Normally they are but on this as they are part of a large CNC chunk the tube below is solid. Quote Link to comment Share on other sites More sharing options...
Lawnmowerman Posted February 17, 2006 Report Share Posted February 17, 2006 Take it to somewhere that has a drill press with a clamp. Will drill that out easy peasy Quote Link to comment Share on other sites More sharing options...
Matt_Tupman Posted February 18, 2006 Report Share Posted February 18, 2006 I'd just mig weld a blob onto it myself and then once it's cooled get some moleys onto it and unscrew itbut thats just me Quote Link to comment Share on other sites More sharing options...
