Ingersoll-Rand’s workhorse rock drill is mean. It can drill a 2″ wide hole up to 18” deep into solid rock — perfect for when the s#!$ you need to break is made of stone. And just think how cool you’ll look weilding it!
The JH40C3 comes with an easily-accessible three-position throttle, reversible pawls, and integral muffler — for whatever that’s worth, considering that you won’t be able to hear the engine over the sound of pulverizing rock. It features a 1″ x 4-1/4” shank, so it’ll accept some heavy duty bits. And it includes a 3/4” NPT air inlet — requiring a whopping 115 CFM of air to do it’s damage. But once you’ve connected it to an air source, you get 2,000 blows per minute.
This thing is not for the faint of heart — or wallet. It’ll run you about a dollar for each of those blows, or around $2,000. Just keep some money back for one hell of an air compressor.
