Stipped heads on Front Rotor Countersunk Philips Screw
 

Anyone have a slick removal technique? I can drill and chisel as well as the next guy, but if someone has a slick trick I'm all ears.

First some Kroil several times over 24 hours.PB Blaster or ATF second best choice.
Mig weld a bolt on it ?But you need to be very good at precision welding.Hold the bolt in a fixture in the correct position about 2mm away from the old phillips head.Do not forget to disconnect the battery!!
Left hand thread easy-out ?

You might be able to take a good hard punch and peck it out after the Kroil or PB Blaster.

Heat up with torch, when hot spray with pb blaster, leave overnight. Impact screwdriver. Worker for my rotor screws.

+1 on impact screwdriver, that's how I got mine out. Replaced them with stainless ones from Lowe's and I put a little antisieze on the fir next time. I got the tool from O'Reilly auto parts for around $8-10.

+2 on impact driver

+3 on impact driver. Worked great for me.

Take a cold chisel and whack a slot all the way up to the outer circumference of the bolt. Then, put screwdriver in the slot, angle it and hit it with a hammer so it applies force in a counterclocwise direction.

+4 on the impact driver.

use a dremel and cut a deep slot into the screw head and use a large regular screwdriver. also after cutting the slot into the head be sure to tap the screwdriver deeply into the new cut to ensure a good bite for the blade.

+5 On the impact driver. I've never used one before and wow! The screws came out with a few taps of the hammer, even the stripped ones! Why didn't I know about this tool already? Man that saves a lot of time and work! Thanks folks!

It has been around for decades , I used ones to remove the windscreen screws on my 1978 FJ 40 in the late 70's
