Drilling steel box section

[psycho_fling]

hi all

im in the process of drilling fixing holes for armour, into steel box section. i tried with ordinary bits but they werent up to it so i bought a bosch bit that worked so much beter did 5 hole in 5mins, but at the moment it isnt performing as it did, any tips?

im using oil and a low speed but cant get it to drill productivly

Are you using a pillar drill?

You can rarely produce enough pressure with a hand drill and this cased the drills to blunt quicker.

well its sort of hard to use a pillar drill on most parts, but on the bits i can get to it was easier

Sharpen the drill

i know you can sharpen bits on a bench grinder but ive been told that is difficult, and that there was a drill attachment you could buy that did the same thing

is this true?

You can buy an attachment yes.

Ive never tried one ...always sharpened mine by hand on a bench grinder.
Difficult ....no ...but then Ive been doing such things for Decades.

do you know what it might be clled the attachment?, so i can search for it-yeh thats what i was told its easy when you have done it for ages

thanks
