Just as soon as we learn how ourselves.
Flap can be found lovingly carressing sockets & torque wrenches at tool stalls the length of the country -a very disturbing sight.

Mmmm, tools..............

Tools

AIR COMPRESSOR - A machine that takes power from an oil-fired power station 200 miles away and transforms it into compressed air that travels by hose to an impact wrench that grips rusty bolts last tightened 30 years ago in Birmingham and rounds them right off.
BATTERY ELECTROLYTE TESTER - A handy device for transferring sulphuric acid from a battery to the inside of your toolbox after verifying that your battery is deader than a doughnut, just like you thought.
E-Z OUT (BOLT & STUD EXTRACTOR) - A tool that snaps off in threaded holes and is 10 times harder than any known drill bit.
HACKSAW - One of a family of cutting tools based on the Ouija Board Principle: It takes human energy into a crooked unpredictable motion, the more you try to influence it's course, the more dismal your future becomes.
HAMMER - Formerly a weapon of war, this device is now used to locate expensive pieces and body parts near the object we were trying to hit.
PHILLIPS SCREWDRIVER - Traditionally used to stab the lids on old style paper and tin oil cans in order to splash and ruin our favourite shirts, this device is now relegated to rounding heads on Phillips screws.
PLIERS - Used to round off bolt heads.
MOLE GRIPS - Used to round off bolt heads when pliers won’t do the trick. Also used to transfer the intense heat of welding to the palm of your hand.
SCREWDRIVER - Used to open beverage containers, can also serve as a chisel. Works well for removing skin from hand as well as making random gouges in other things.
WIRE WHEEL - Cleans rust and corrosion from old bolts and flings them somewhere under the workbench at the speed of light. Also good for removing fingerprints (from fingers).

Thought I would add.

There is a fluted type of screw extractor, you drill the hole then hammer the fluted bit in and there is a nut which goes on the flutes and you use a spanner to remove it. I have had far more luck with the flutted ones..

If possible use a drill guide of some sort. the flutted extracors i have came with a set of drill bushings. Grease is good for catching the swarf..

Another thing that often works is a lh drill bit, you can buy them from drill shops but I ground a rh hss drill to cut lh, it had positive rake but it cut enough to grip and unscrew the broken bolt..

The fluted thing's worth knowing -thanks for that. Never had much success with extractors. They usually snap off & cause twice as much hassle trying to remove both them & the stud!

the bit about them breaking if you dont use the proper wrench is correct....I bought some Draper stud extracters the other day and thought "use a proper wrench??? yeah right bol**ks" got them back to the garage first bolt came out great using an ajustable spanner, came to do the second one and snap!!! :-[ :-[ it broke,  not only did it break but the piece that flew off stuck in my arm. so I would recommend using the proper wrenches ....I have bought one now and another set of extracters  ;)
