I am hoping some of you have the answer: bought a used utility trailer. I am installing E Track on the floor. I am finding it nearly impossible to drill the 1/4" holes I need into the steel cross members! The wood floor is attached to the cross members using 1/4 self tapping deck screws. I know from the guy that built the trailer that they drilled a 7/32" pilot hole and then tapped with these screws.

I tried to do the same thing. Broke two bits in the process and still have not drilled a hole! My thought was to drill 1/4" and use bolts to attach. But it doesn’t really matter what approach if I can’t get a dang hole drilled.

Thoughts? Slower drill speed, faster, cutting torch, what?

TIA,
