Backbore Comparisons

The table below provides comparisons of some of the more common backbores. They were obtained with a low tech method using pin gauges and a Vernier digital caliper.The data was then imported into an Excel spreadsheet and imported into RhinoCAD as a point cloud, from which the curves are drawn.

Although this is not a sophisticated method, the results are highly reproducible to about 1/1000 of an inch and are consistent when calibrated against known dimensions of Wedge backbores turned on a CNC lathe.

To see two backbores together find the first one along the top row and click on the X corresponding to the row for the backbore to which you wish to see it compared. The image will load without leaving the page.
