Broken centre drill recovery

[Gilly]

here's a bit of advice
john S Advice is spot on (forgive the pun) centre drills old hat
when you have broken the end of your c/drill into the the job this then becomes embeded
into the material ,so if you try to remove it the tool will push off toolsteel on toolsteel
hence the banana
so heres what to do get a carbide tool (stronger then toolsteel) low revs and just feed in
slowly until embed toolsteel is removed then you can drill it after
hope this helps
best regards
