holes up to 1 inch can be don e by hand relatively fast using a two
drill method

rule one make your pilot hole slightly smaller than the web , really
stops the grabbing


rule two use a good Milwaukee 1/2 inch hole shooter hand drill @400 rpm


apply steady starlight pressure to the bit

i like to derake my bits till they just will make a chip but not start a
curl if that makes sense , a good bit of rpm helps


the drill i use has no side handle and i usually only hold it from
rotating lightly most of the pressure is going straight behind the bit


heres another trick

stand on the extension cord keeping it really short length to the tool ,
that way if it grabs it unplugs itself

i drill a lot of 5/8 3/4 and 1/2 holes in machine frames on site and i
can out-do the mag drill guys by 3 to 1

i have successfully run in 5/8 -11 taps by hand drill to , won lunch
that day
