1. [Shop-talk] Helicoil in aluminum (score: 1)

I'm about to install a helicoil in an aluminum block. The tap calls for drilling a 21/64" hole. Since it is aluminum should I drill the hole just a tad smaller? If so how much? Thanks Bob Nogueira ("

Last one I did (in a TR6 transmission case) I drilled the hole 21/64. Worked just fine for me... Jeff Scarbrough Corrosion Acres, Ga. _______________________________________________ Shop-talk@autox.t

Looks like you ar installing a 5/16-24 Helicoil. Use the 21/64 drill. Trust the engineers that designed them. Greg G. Osseo, MN _______________________________________________ Shop-talk@autox.team.ne

I don't think it matters much. The tap seems to ream the hole out if it is undersize. I've even been known not to drill, if the hole is completely skinned out (and the base metal is soft). -- Randal

...with a brief moment of consideration as to whether one really wants a fine thread in aluminum in the first place, and whether it wouldn't be possible to use 5/16-18 instead. John. ________________
