Posted: Sun Oct 08, 2006 1:37 pm Post subject: Drill bits

I just ran through about a half dozen drill bits drilling the cotter pin holes in one wheel axle of my RV8A.  That is some tough steel!  Does anyone have a suggestion on what kind of drill bits to use here?  There has got to be something tougher than the "titanium" bits I got at Lowes.

   

  Thanks,

You lubing it?  We drilled those a few weeks ago at Bill’s house and it was a snap.. didn’t take much (same bit for both legs).. also, low speed on the drill would help too.. (eg, I wouldn’t use air drill for that)  

   

From my general experience, cobalt bits lasted longer than hss bits especially if you try drilling any steel parts.

I was lubing it, but I also was using high speed (air drill).  I'll try it a bit slower.

Craig, I used cobalt drill bits, drill slowly - like  200-300 rpm, use oil.  Spinning too fast can further harden the metal in  the hole you are drilling as well as dull your bit.

I found cobalt bits work well.  Keep them  lubed with marvel mystery oil and drill slowely.

Listers,

   

  Thanks for the feedback on drilling hardened steel.  Lessons learned:

   

    Use cobalt bits.  (actually, I started with them but I thought another type might work better and resorted to the Lowes "titanium" bits ..... bad choice)  
Drill slowly.  I was using an air drill and going much too fast.  
Lubricate.  I was using some of my air tool oil, but this was not very good at such high drill speeds.  Thanks for your help.

   

  Craig
