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
Also aluminium is best drilled with a larger point angle. When drilling plexiglass, the risk of cracks when the drill goes through the mate-rial is reduced with a larger point angle. Centering drills usually have a 90Â° point angle.A drill bit needs to have the right lip clearance angle to cut the material.The clearance angle varies from 7Â° to 14Â°.ount the Drill Bit For small drills, up to approx. 8 mm (5/16 ) you can use the special Tormek Magnifier.Turn the drill holder so the bevelled side points towards the machine.The cutting edges should be parallel to the pin in the Magnifier.
