What kind of bit will drill stainless

[Realgun]

I need to get 1 of the 5 bolts out of the tilt cylinder. It was the only 1 that broke off when turning. I tried a regular bit and a left handed bit and it does no good.<br /><br />Force 85Hp 856X8A not that that matters much

I have used a titanium bit with some success. Then used screw extractor of the correct size to remove the bolt. However, if it looks like you might damaage the cylinder, take it to a machine shop. They have all the right tools.

I always use a regular mettal bit. Start of small and work your way up using oil to cool the bit

Hi,i have just drilled out three head bolts out of my 1990 force 50, i had lots of problems then bought some new standard metal drill bits and i found that the drill bit would only bite when i applied lots of pressure and kept the speed low and kept it well oiled and if the bit got blunt then i would put a new edge on the bit and it worked fine... as i am now just clearing away old gaskets and getting ready to rebuild head and exhaust port.good luck...

If you know how to sharpen bits....flatten the angle out a little and bring the point to a drill point and use a cuuting oil on it.

A good Grade of cobalt drill bit will drill out that stainless stud, make sure you have it centered, and keep it lubed.

Just a piont. If you over heat the stud/bolt with a dull drill, you can work harden the stainless.. Keep it cool!
