I was thinking the same thing. To think that all these years I've been using that wacky product called "cutting oil". But I'll give the water a try. It can't do any worse (on stainless). Don't know about aluminum bronze. I've never tried to drill that. Howard On 3/22/05 10:18 PM, "IDCLLC@aol.com" <IDCLLC@aol.com> wrote:
Cool!
I've always used oil for dispersing heat when drilling steel, never water. I guess the big thing is keeping the bit cool. Once it's cooked, you are too; no temper, no edge, no go.

Just an aside ....
The trick to drilling stainless is to keep it wet while drilling either by a small stream of water from a garden sprayer for large parts or by being submerged in a water bath for small parts. (Some friends and I built a 55' x 14' houseboat for Lake Powell completely out of stainless ... just imagine how many holes were drilled! Once this trick was learned we never tried to drill stainless without water.)
