desert_sailing said:Started to remove the bulkhead.. super annoying to get rid of the rivets that are attached to the vehicle and one section of it. I am not having much luck. I used a bit (titanium) to drill it out.. but I was breaking bits.. went to larger size and stilll nothing.. LOL the rivet started to just spin...lol Went and bought one of those rotary tool things thinking I could just cut the head off.. but those damn flimsy cutting wheels that come with it are a joke.. its like a cookie and break at the slightest touch..I even tried a chisel and hammer..that seemed to show the most potential but my chisel is dull and worn down.. maybe a new sharp one would be better?
Any suggestions?
The most common cause of breaking drill bits is you are wiggling the drill, causing the bit to (try to) bend.
Rivets are a bitch to drill out. I use a diagonal cutter to hold a spinning rivet head while drilling with some success.
It is almost impossible to hold a cutting wheel steady enough to cut the head off a rivet. Get a grinding wheel that fits your drill.
Yes, a chisel needs to be sharp. Best to use a file to sharpen. A grinding wheel sharpens quickly (and destroys the temper).
