You want to know all about photo encaustic. You love photography and want to put more of yourself into your work. You want to have fun exploring your images while being more hands-on. I love that too. That is what drew me to photo encaustic. That and the way the light pulls me into the image.
I would like to know why 118 degrees made the standard tip angle for a drill bit.Or for that matter, 135 degrees? 1. Is there anything called standard tip angle? 2. What factors determine the choice of the tip angle? P.S: I posted the same question in Aerospace forum : http://www.eng-tips.com/viewthread.cfm?qid=347077
No center point is needed, as these 135&#176; quick cut points are self&#45;centering and penetrate faster with less pressure. Will not walk or wander at the starting surface. Extremely heat&#45;resistant, these drill bits are most efficient in drills that operate at 1500 RPM or more. Cobalt high speed steel drill bits offer a 12X life rating, compared to standard 118&#176; point drill bits..
