Oh, Oh! So did you try to drill a big hole all in one pass? Try a small
diameter carbide # 40 or so, slow turning, heavy pressure, cutting oil, &
don't side load the bit to break it. Good luck

Subject: [rebel-builders] Drilling through steel leaf springs:
work-hardening
Hi All,
Tried to drill through my steel tail spring this morning but managed to
render
half the hole "work-hardened" (not enough lube and/or cooling). What do I
do now? Carbide tipped bits? Other bits?
Hope someone can help me avoid buying a new tail spring!!
