Pilot Bearing Welded to crank?

Pilot Bearing Welded to crank?
So I'm doing some work for a guys Camaro. 99 z28 M6. Im swapping in an ls7 clutch, tick master and a ram slave. I got the trans and all out but im having extreme trouble with this pilot bearing. The trans input shaft has soo much play it destroyed the pilot bearing and now I cant get it out to replace it. It seems like it just got soo hot that it welded itself to the crankshaft. I tried using the pilot removal tool and broke one of the fingers. I tried another and still no luck. It grabs behind the pilot but when I use the pulley to pull it out, it slowly just grinds off the metal and doesn't budge the bearing at all. I feel like my only option left is to try using a die grinder, but I don't want to risk messing up the crank. Does anyone have any suggestions? anyone deal with this before?
No chucks came out, only metal dust.

Mine was pretty similar. Also broke a finger off the puller. Used a carbide bit and cut into it and used a chisel and once I broke that tension it came out. Now when I was cutting into it I did get into the crank a small amount. I deemed it ok and drove the new bearing in and been like that for years and a bunch of track passes.

I found this blind hole puller from AutoZone loan a tool worked very well....although my pilot bearings have not been like OP's
the cut/chisel method may be needed but if the tool is available near you, worth a shot

Same here I had to chisel mine out too. Seems common for the needle pilot bearings. I went with the pilot bushing when I replaced mine so I could use the blind hole puller next time.

Awesome thanks fellas! it ended up coming out fairly easy after I grinded off one side then I used a chisel. No damage to the crank.
