Not unless it was reasonably loose. Usually when faced with this, I drill into the bolt with a very hard drill bit a tiny bit thinner than the bolt - ie if it's a 3/8 bolt, I drill in first with a 1/8 drill to create a guide hole, then after with a 5/16 drill to cut right through, yet not harm the threads. You have to be very careful to stick to an exactly straight course. After the hole is cleared, I pull the threads left from the bolt out as far as I can, then use a 'clearance' tap of bolt size to re-tap the hole.
I have a pair of very thin, strong, long nose pliers for that .It almost always works for me.
It depends on the drill you use. With diamond drills it can be done in less than two days, but with a cheap, blunt drill, it could take over three weeks.
There are a few ways of doing it depending on the exact geometry, size, and tolerance. You could drill the hole before cutting the profile that results in the partial entry. You could drill very carefully and slowly, stepping up the drill from a small size to the final size, if the smaller size would enter complete. You could make a fixture to fit over the part so the drill is guided into it. There are low melting alloys you can pour around the area to make a complete entry. You then melt the alloy away.
A 40mm masonite drill bit could work using the right drill. But consider using a coring machine instead because its concrete.
It sounds like you need a variable speed drill. There was an item on the market a few years ago that you could plug your drill into and control its speed. I haven't seen one lately since most new drills have variable speed built into the drill. On a drill press all you need to do is move the drive belt to the smallest pulley on the motor and the biggest pulley on the drill spindle.
You will have to drill them out and extract the broken piece so you can thread in new ones
Are you handy with a center punch, and a drill? If so, the best way to do this is to drill a hole in the center of the stud, and along with penetrating oil, an/or heat from a torch, use an easyout to extract the broken stud from the intake.
to extract the oil out of the ground
That is a drill bit designed to remove partial drill bits that have broken in a hole
The purpose of an integrates petroleum company requires it to find, drill for, extract and refine oil and gas. BP (British Petroleum) followed this mandate. They were confident that they could do so in a environmentally safe manner and obtained all required permits.
Remove the broken bolt and replace it with a new one. There are several ways to remove that broken bolt. You can remove the valve cover and weld a nut to what is left of the bolt, wait for it to cool off then unthread the broken bolt. You can also drill out the center of the broken bolt and use an easy-out. You can also drill into the broken bolt with a left handed drill bit, sometimes the drill bit will catch and spin out the broken piece. I would go with the first suggestion.
''Yes'' by one big drill!!!
drill it out 6mm drill to 13mm drill but do not go deeper than 13 mm.
You extract oil (black gold) by pipes, a drill thingy and...mud.Yes, mud. Look it up if you're not sure then!Bye! xx
you can pick up a kit for this at any hardware store. a small drill bit has to be bored through the center of the broken screw, than a reverse-threaded bit backs out the broken piece.
You must extract the bolt end with a drill and an extractor. Do not attempt unless you are a handy-dandy person! It is easy to foul up. Consult someone who has experience. Y-THINK-Y
generally to remove a broken bolt, you will need a drill and an easy out
