Thread: DRILLLLLL!!!

Had to punch a hole in my bathroom floor as I am remodeling it right now. As the floor is tile on a six inch concrete slab and my hole size is 1" dia, I went ahead and rented a drill that would do the job fast. Boy did it! This thing went through the floor like it was warm butter on a texas side walk in the summer!

Hilti says it all

Reminds me of a story I heard of two IT guys I knew who had to drill a cabling hole through one of those hefty tiles you get in data centres. One of them got the drill with the hole cutter and started drilling away. It seemed fast at first but slowed down. "Let me have a go" said the second guy. Still seemed slow to cut, so he really put his weight into it. A few minutes later he was exhausted with sweat dripping off his brow. They took turns, and after about half an hour of this they finally broke through. Of course they eventually realised the drill was in reverse!

Used to use a very similar drill with a 20"x3/4" wood boring bit for bolting corbel blocks in pole buildings. If you've never had a drill like that bind up half way through a 16" thick post while you're on a ladder 20' in the air, you haven't lived.

Steve, that sounds like my stepfather's stories. he used to run a big drill for doing electrical. drill through all the studs. monster drill, can't remember the detail now. he said sometimes other guys would try a turn on it, one tmie a guy got thrown off the second story when it bound up.

Thought I was going to break an arm one time doing that sort of thing, a real eye opener!

Hilti are top of the shelf
I have a pro Bosch. It's still very good pro stuff, but not as good as Hilti. I could not afford a Hilti at that time. The Bosch has never let me down, drilling through over a feet of reinforced concrete, hitting the occasional piece of rebar...

Anyway, these days, most of the better class drills have kickback protection that will disconnect the drill shaft from the motorif it jams in the hole.
Someone I used to train with shattered his wrist like that. he was gripping the drill tight, and it was one of those monster sized drills. At one point it jammed, it kicked, andbefore he could let it go, his wrist was kaput.

I wish I could have justified buying it, but I only needed it for one hole so I rented. I can total see why everyone speaks highly of them though.....

Thank the sweet baby jesus I haven't lived.

But Hole Hawgs are so nice when you need them....

And how did I live without a good hammer-drill?

I'm a commercial Industrial electrician and to be honest I refuse to use hole hawgs, they are in my opinion the most dangerous tool made, and they do not come with clutches you have to just hold on and go for the ride.

Unfortunately I have lived.
