A cetnre punch applied oliquely near the circumference often works too..

The wookshp manual [1] I have alongside me gives the removal method as 
drilling a hole down the middle and then using an easy-out. Does that 
term exist across the Pond? It's a tapered tool with a left-hand thread 
on the otuside. Put it down the hole, turn it anticlockwise with a tap 
wrench [2] and it bites into the sides of the hole and turns the 
shear-head olt anticlockwise too.

I have neve seen RH thread easy-outs for removing ledt-handed shear-head 
bolts, which suggests that said bolts would be a little harder to remove

[1] Yes it's a car manual. The bolts hold the ignition switch/steering 
lock to the column. I have neve seen such bolts used in classic computers

[2] That's tap as in 'tool for cutting female screw theads'
