Another thing that works well for off center holes is called an "annular cutter". They look like a hollow end mill, are not meant for side milling, but drilling holes. I've seen the used with mag drills many times. As you say, a drill bit is the wrong, and dangerous tool -- 73 de KG2V Charlie _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
