| Many applications for Dura-Bar end up having a hole machined through the center. Often this is one of the longer machining steps. To help speed the machining process, Dura-Bar offers Dura-Tube, trepanned bars from a variety of round bar stock sizes to meet a wide range of customer tubing applications. |  |
| The Dura-Bar trepanning process and modern equipment assures customers of the most precise and accurate trepanned products to meet exact specifications. All tubes are left with sufficient stock for clean-up in most applications.
Many Dura-Tube sizes are available from stock. Many others can be custom ordered. |
Minimum Dimensions:
| 0.000" - 3.000" | 0.562" | 1.215" |
| 3.001" - 6.000" | 0.625" | 1.250" |
| 6.001" - 12.000" | 0.687" | 1.375" |
| 12.001" - 16.000" | 0.750" | 1.500" |
Example: Wall thickness minimums are based on actual O.D. and I.D.
Example: 3.000" as-cast x 2.000" I.D.
Actual: 3.110" O.D. x 1.750" I.D.
Overall wall thickness: 3.110" - 1.750" = 1.360"
Single wall thickness: 1.360" / 2 = 0.680"
