IAP Bushings & Tubes Reference

The IAP Bushings & Tubes app provides a searchable and sortable interface to over 4000 pen kits from most of the major kit suppliers. The app displays detailed tube and bushing specifications and drill bit requirements for every kit in the app database. These kit details can be emailed or printed via Air Print. You can create a favorites list of your most frequently used kits for faster access to those kits rather than searching through the entire app database every time you need to reference those kits. You can also reorder the database by your preferred supplier order.

The app also includes a drill bit converter for converting between inch fractional, inch decimal, metric and gauge drill sizes. Conversions to inch fractional are made to the nearest 1/64" and conversions to gauge drill size are made to the nearest gauge drill size (107-1 and A-Z). An error factor is displayed for inexact conversions to inch fractional and gauge drill size.

A 30-digit, 4-function calculator is included in the app. It has several advanced features not found in many simple calculators including a memory cell and the ability to display data in decimal or scientific notation.

Photos, Instructions and Bushing Drawings are available for most of the kits. When instructions or bushings are available, they may be viewed, mailed or printed.

The app also contains several lists of useful references: Worldwide Suppliers of pen kits with links to take you directly to their web site; Helpful Penturning videos with links that will take you directly to the video; and Penturning Tutorials with links that will download the tutorial to your device for viewing in the app or to email or print.

The app will automatically download database updates and the kit reference files from the IAP server.
