Removing a broken bolt easily

Problem: When faced with the inevitable task of removing a broken or sheared bolt, there is a way to make the job easier.

Solution: Keep a small assortment of left-hand drill bits handy and the job will generally be easier. Carefully centre pop the broken stud with a spring-loaded centre punch. This is much more accurate than using a hammer and punch.

Start with a small left-hand drill bit chucked in a variable speed drill turning backwards, and keep working up in bit sizes as required and you will probably find the stud backing out with the drill bit before much time has passed.

It’s a quick and easy solution, and also eliminates the need to find the supply of easy outs (which are usually missing). Remember, start small, be accurate with the first drill bit, and go carefully so you do not break the drill bit off too.
