Thank you very much Steve, That PDF was very much spot on info I was lookking for. I probably could not find it, because I was bypassing all stuff about guns - because I'm not making one. Logical or not, but that was pretty much I should have been lookking. Drilling lubrication holes on marine diesels is not easily converted to garage level application. The info I got made me feel better. My application should be whole lot more simple, because I need whole lot shorter hole and I'm not going to load this one. This is going to be interesting :coffee: reading some time and then a little bit of application :zap: The only thing I'm worried about is the spindle material. I have very little free machining leaded steel (and dimater is too small) and pretty much the only right size material I have is mystery tempering steel that eats my convetional drills...although turns beatifully with inserts. But one step a time. Thank you, Pekka |

Would it be possible to grind a masonry (concrete) drill to a suitable angle and use that together with a suitable sleeve? In that case you get a carbide tip that well can handle tough stainless. BR /Peter |
