## Machine-readable catalog data (CAM/CAD/tool-library import)
- [Downloads hub](https://robbjack.com/downloads): every machine-readable format in one place — Fusion 360 and Siemens NX libraries, ISO 13399 master catalog (JSON/CSV), per-tool API, CAD, and the Mastercam route.
- [Fusion 360 tool library page](https://robbjack.com/downloads/fusion-360): what's in the native .tools library, the embedded "RobbJack tested" cutting presets, exact import steps (Manufacture workspace → Manage > Tool Library → right-click Local/Cloud → Import Libraries), and troubleshooting.
- [Fusion 360 tool library file](https://robbjack.com/data/cam/robbjack-fusion360.tools): native Autodesk Fusion 360 .tools library — every standard RobbJack end mill and slitting saw with exact geometry PLUS RobbJack's tested cutting data as per-material start-value presets (spindle speed, feed, chip load, stepover/stepdown).
- [Siemens NX tool library page](https://robbjack.com/downloads/nx): what's in the native ASCII tool database, the "RobbJack tested" cutting-data comment rows, exact merge steps (back up tool_database.dat → paste the RobbJack block below the END_MILL_NON_INDEXABLE FORMAT → restart NX → Retrieve Tool from Library), units (decimal inches), and troubleshooting.
- [Siemens NX tool library file](https://robbjack.com/data/cam/robbjack-nx-tool-database.dat): NX native ASCII tool_database.dat format (pipe-delimited DATA records, standard END_MILL_NON_INDEXABLE 35-field layout) — every standard RobbJack end mill and slitting saw with exact geometry PLUS RobbJack's tested cutting data as comment rows (SFM, RPM, chip load, feed, WOC/DOC per material).
- [Master catalog page](https://robbjack.com/downloads/master-catalog): the ISO 13399 story — what's in the JSON/CSV, the shared parameter legend, the parametric saw rule, SHA-256 integrity verification, and per-tool API reference.
- [Mastercam page](https://robbjack.com/downloads/mastercam): the honest answer for Mastercam users — no hand-built .tooldb (closed format, corruption risk); MachiningCloud/ToolsUnited listing in progress; the CSV catalog + per-tool API work in Mastercam today.
- CATIA / TDM / Zoller / WinTool and other ISO 13399 tool-data managers: use the master catalog JSON below or the per-tool ISO 13399 feed — no separate CATIA file is needed.
- [Master catalog JSON](https://robbjack.com/data/robbjack-master-catalog.json): every standard catalog tool with ISO 13399-coded specs (DC, DMM, APMX, OAL, RE, CW…) in both inches and millimeters, plus series, coating, and product-page links. Slitting saws are also described PARAMETRICALLY: any .0001" thickness between a family's thinnest and thickest standard size is a standard orderable part number (the file gives each family's range, step, and part-number encoding rather than enumerating sizes).
- [Master catalog CSV](https://robbjack.com/data/robbjack-master-catalog.csv): the same tools flattened one row per tool (inch + mm columns), Excel-friendly.
- [Manifest](https://robbjack.com/data/robbjack-master-catalog.manifest.json): schema version, generated date, tool count, file sizes, SHA-256 checksums.
- Per-tool live data: https://robbjack.com/api/iso?tool=<partNumber>&format=json (JSON; default is CSV; units=in|mm|both) — works for every catalog tool AND for any in-between saw thickness part number.
