prechambers mods?
hy there,
a pack of 10 x3mm HSS Cr 0.7 drill bits (those cobalt) maybe cost 15€ i dont think the issue is the cost. and amasing is that the drill bit u can Sharp. use again and again til the bit is over. i went through the same usually ending the hole is tricky thats why u shoul use a hand driller.
the inside hole is 6,7mm on the pre cups marked 606 02.
heating the PC wont do any good, what one could do is heating to where we can distemper the metal and after doing the holes heat treat them again for hardning . something is not so easy to do. simply cause we dont know the cokking temp.
regards
