For optimized display, we suggest upgrading your browser to Internet Explorer 7 or newer. You may not get all the dimension formatting possibilities there, because it's a note, but it'll do what you want. The Hole Callout tool adds driven diameter dimensions to holes created by the Hole Wizard or circular cut features. All rights reserved. By selecting the proper tool sequence, the tool life of the carbide drill will increase dramatically. Misalignment can be detrimental to part quality and function.

You can customize these data tables as required. No fillets/rounds/radius. Figure 3-35 illustrates dimensioning chamfers, 45° chamfers, and internal chamfers. By having a 90° countersink step angle in the drill, the hole and chamfer are produced in one operation. The NC spot drill is used as a lead tool prior to drilling to create the 90° included angle. A second file, calloutformat_2.txt, is a simplified version. You can edit either file. Tables.
