How long did it take you to drill

[DaffyXJ]

SO seldom do I waste time with cutting oil. too damn messy. I save it for tapping.:gee:

With out some sort of oil, even wd40 if need be, it will take 300 lbs to get it done. THink about your drill press, are you pulling 300#s or even 50#s of force to go through a 1/4 inch plate. Oil the bit, keep it cool, it will cut better and last longer.
my $.02.

new 5/8 bit ( ~ $ 19 ) , Medeival snap on air drill ( with 150 psi of shop air ) , and 1 shot of pb blaster . went through it like it wasnt there . 3 minutes or less .
i didnt need to apply a whole lot of pressure , as the bit fed itself in quite nicely .

why is everyone paying so much for drill bits? My workplace furnaces all the bits i could ever want LOL When I drilled mine it took about 1 minute. Oil and sharp bit.
