I take delivery today of the steel for my power rack project.
75 x 75 x 3mm square hollow section for the framework and solid bar for the safety pins, plate holders etc. I plan on spacing the holes 1" apart. I've been lifting 30+ years and using a wooden power rack with 2" spacings for the last 4. The holes are too far apart for my needs.
Now to the question. I don't have a pillar drill so holes through the box section will have to be drilled on opposite faces separately. This gives me roughly 700 holes to drill for a 7 foot high rack (double it if you count the pilot holes). That's not daunting, but the potential cost of drill bits is! What's the best way to maximise the life of a drill bit? Cutting fluid? Slow drill speed? Better quality bit? I've never drilled this many holes at the one time, so it's an unknown to me.
(Hole size is 10mm diameter)
Thanks
